Image Resizer has 5 dedicated pages, each pre-configured to one specific job with its own verified dimensions: #### Resize Image for YouTube Thumbnail URL: https://freemytools.com/image-resizer/youtube-thumbnail/ Output: 1280×720 pixels, 16:9, file size under 2 MB. Specification verified 2026-08-05 against https://support.google.com/youtube/answer/72431 (confidence: high). YouTube thumbnails have two requirements, and most tools only handle the first. The dimensions are 1280×720 at 16:9 — but there is also a hard 2 MB file-size cap, and uploads over it are rejected outright. A high-quality photo scaled to 1280×720 will often land above 2 MB, which is why so many creators get a resize that looks right and still will not upload. Why 1280×720: 1280×720 is the smallest size that stays sharp everywhere YouTube shows a thumbnail — from a 4K TV grid down to a phone search result. YouTube requires a minimum width of 640 pixels, but thumbnails at that size look soft on large displays. Going bigger than 1280×720 rarely helps: YouTube re-encodes and downscales anyway, and larger files push you toward the 2 MB ceiling for no visible gain. Caveats: - The 2 MB limit applies on mobile uploads. Desktop allows up to 50 MB, but staying under 2 MB is the safe target since it works everywhere. - Text near the bottom-right gets covered by the video duration badge. Keep the corner clear. - Thumbnails are displayed as small as roughly 246×138 in sidebar suggestions — check yours is readable at that size. - JPEG almost always beats PNG here. PNG keeps every pixel and blows past 2 MB fast; JPEG at 85% quality is visually identical at this size. Questions this page answers: Q: What is the maximum image size for a YouTube thumbnail? A: 2 MB. Uploads above that are rejected, and it is the most common reason a correctly-sized thumbnail still will not upload. This tool compresses to stay under the limit automatically — lower the quality slider if a detailed photo is still too large. Q: How do I reduce the file size of a YouTube thumbnail? A: Export as JPEG rather than PNG and lower the quality setting. At 1280×720, JPEG at 80–85% quality is visually indistinguishable from the original but typically a fifth of the size. This page shows the resulting file size before you download, so you can check against the 2 MB limit. Q: What image size is best for a YouTube thumbnail? A: 1280×720 pixels at a 16:9 ratio. That is YouTube's own recommendation and it stays sharp from a 4K television down to a phone search result. The minimum accepted width is 640 pixels, but thumbnails that small look noticeably soft on larger screens. Q: Does YouTube compress thumbnails? A: Yes. YouTube re-encodes every thumbnail and generates several smaller versions for different placements. That is why uploading something far larger than 1280×720 gains you nothing — it gets downscaled regardless, while costing you file-size headroom against the 2 MB cap. Q: Can I use a PNG for a YouTube thumbnail? A: You can — YouTube accepts JPG, PNG, GIF, and BMP. But PNG is lossless, so a photographic thumbnail can easily exceed 2 MB. Unless your thumbnail is flat graphics or text with hard edges, JPEG will give you the same visible quality at a far smaller size. #### Resize Image for Facebook Cover Photo URL: https://freemytools.com/image-resizer/facebook-cover-photo/ Output: 851×315 pixels, ≈2.7:1, file size under 100 KB. Specification verified 2026-08-05 against https://www.facebook.com/help/125379114252045 (confidence: high). A Facebook cover photo is 851×315 pixels — an unusually wide 2.7:1 strip that matches nothing else on the platform. The complication is that Facebook does not display the whole image the same way everywhere: desktop shows roughly 820×312, while mobile crops to about 640×360, cutting in from the sides. Anything important near the left or right edge disappears for mobile visitors, which is most of them. Why 851×315: 851×315 is the size Facebook stores and serves from. Supplying exactly that avoids any resampling, which is where cover photos usually lose their crispness. Facebook also recommends keeping the file under 100 KB — above that it applies heavier compression of its own, and text and logos are the first things to visibly degrade. If your cover is mostly flat colour or text, a PNG under 100 KB will stay sharper than a JPEG. Caveats: - Mobile crops the sides, not the top and bottom. Keep logos and text within the middle ~640px or they will be invisible on phones. - On desktop, your profile picture overlaps the lower-left corner. Leave that area clear. - Facebook compresses hard above 100 KB. For text-heavy covers use PNG and stay under the limit. - The minimum is 400×150. Anything smaller gets upscaled by Facebook and looks blurry. Questions this page answers: Q: What size should a Facebook cover photo be? A: 851×315 pixels. That is the size Facebook stores and displays from, so supplying it exactly avoids resampling. It displays at roughly 820×312 on desktop and crops to about 640×360 on mobile, so keep important content centred. Q: Why does my Facebook cover photo look blurry? A: Usually one of two things: the source was smaller than 851×315 and Facebook upscaled it, or the file was over 100 KB and Facebook compressed it heavily. Resize to exactly 851×315 and keep the file under 100 KB — this page shows the output size before you download. Q: Why is my Facebook cover photo cut off on mobile? A: Mobile crops in from the left and right, showing roughly 640 pixels of the 851 wide. Anything near the edges is hidden on phones. Keep logos, text, and faces within the central portion of the image. Q: Should I use a JPEG or PNG for a Facebook cover? A: PNG if your cover contains text, a logo, or flat colour — it keeps edges crisp and Facebook's compression is kinder to it. JPEG if it is a photograph. Either way, aim to stay under 100 KB, above which Facebook applies its own heavier compression. Q: What is the minimum Facebook cover photo size? A: 400×150 pixels. Facebook accepts it but upscales to fill the space, which looks soft. Use 851×315, or 1702×630 if you want extra sharpness on high-density displays. #### Resize Image for LinkedIn Banner URL: https://freemytools.com/image-resizer/linkedin-banner/ Output: 1584×396 pixels, 4:1, file size under 8 MB. Specification verified 2026-08-05 against https://www.linkedin.com/help/linkedin (confidence: medium). A LinkedIn profile banner is 1584×396 pixels — a 4:1 letterbox that is wider and shallower than almost any other social header. The practical difficulty is not the resize, it is the layout: your profile photo sits over the lower-left of the banner on desktop, and mobile crops the visible area down to roughly 1350×220. Designs that look balanced in an editor routinely end up with their headline hidden behind an avatar. Why 1584×396: 1584×396 is LinkedIn's stated size and it maps cleanly to a 2× render of 792×198, which is why it stays sharp on retina laptops — the audience most likely to be viewing your profile. LinkedIn accepts files up to 8 MB, which is generous enough that compression is rarely the constraint here. The constraint is composition. Caveats: - Your profile photo overlaps the lower-left on desktop. Keep that corner empty. - Mobile shows roughly the central 1350×220. Anything outside that is cropped away. - A personal profile banner (1584×396) is not the same as a company page cover (4200×700). They are different pages and different sizes. - Fine text under about 24px at this size becomes unreadable once LinkedIn scales the banner down on smaller screens. Questions this page answers: Q: What size is a LinkedIn banner? A: 1584×396 pixels for a personal profile, a 4:1 ratio. This is different from a company page cover image, which is 4200×700. Using the wrong one leaves you with visible letterboxing or a heavy crop. Q: Why is my LinkedIn banner cropped? A: Mobile shows only the central portion — roughly 1350×220 of the 1584×396. On desktop, your profile photo covers the lower-left corner. Keep text and logos inside the central safe zone and away from that corner. Q: What is the LinkedIn banner safe zone? A: Roughly the central 1350×220 pixels. Content inside that area is visible on both desktop and mobile. This page includes a 1350×220 preset so you can check your composition against it before uploading. Q: How do I stop my LinkedIn banner looking blurry? A: Supply exactly 1584×396 rather than letting LinkedIn upscale something smaller. Export as PNG if the banner contains text or a logo. LinkedIn allows up to 8 MB, so there is little reason to compress aggressively. Q: Can I use the same image for my LinkedIn banner and company page? A: Not without resizing. A personal banner is 1584×396 (4:1) and a company page cover is 4200×700 (6:1). The ratios differ, so reusing one crops or letterboxes the other. #### Resize Image for Instagram Story URL: https://freemytools.com/image-resizer/instagram-story/ Output: 1080×1920 pixels, 9:16. Specification verified 2026-08-05 against Third-party consensus; Meta publishes no organic pixel spec (confidence: medium-high). Instagram Stories are 1080×1920 — a 9:16 vertical frame that fills a phone screen edge to edge. The same dimensions apply to Reels covers and Story Highlights, so one correctly sized image covers all three. What trips people up is not the resize but the interface: Instagram overlays your profile name at the top and the reply bar at the bottom, and both sit on top of your image. Why 1080×1920: 9:16 matches the aspect ratio of essentially every modern phone display, so a 1080×1920 image fills the screen with no letterboxing. 1080 pixels wide is Instagram's maximum served width — supplying more gets downscaled with no benefit, and supplying less gets upscaled and looks soft. If file size matters on a slow connection, 720×1280 keeps the same ratio at roughly half the pixels. Caveats: - Keep text within the central ~1080×1420. The top ~250px and bottom ~250px are covered by Instagram's own interface. - Reels and Story Highlights use the same 1080×1920, so one image works for all three. - Instagram re-compresses everything on upload. Starting from a clean 1080×1920 gives the best result; upscaling a small image first makes it worse. - Uploading a non-9:16 image gets letterboxed with blurred bars or cropped — neither looks intentional. Questions this page answers: Q: What size is an Instagram Story? A: 1080×1920 pixels, a 9:16 vertical ratio. This fills a phone screen completely. The same size works for Reels covers and Story Highlights, so one export covers all three formats. Q: How do I resize an image for Instagram without cropping? A: Resize to 1080×1920 with the fit option, which scales the whole image to fit inside the frame and pads the remaining space rather than cutting anything off. Use fill instead if you would rather crop the edges and have the image cover the whole screen. Q: What is the Instagram Story safe zone? A: Roughly the central 1080×1420. Instagram places your profile name across the top and the reply bar along the bottom, each covering about 250 pixels. Keep captions and calls to action inside the middle band. Q: Is an Instagram Reel the same size as a Story? A: Yes — both are 1080×1920 at 9:16, so an image sized for one works for the other. The interface overlays differ slightly, with Reels adding caption and button elements along the right side and bottom. Q: Why does my Instagram Story look blurry? A: Almost always because the source was smaller than 1080×1920 and got upscaled, or it was heavily compressed before upload. Instagram re-compresses on its side too, so start from a clean 1080×1920 original and let it do the compression once. #### Resize Image for Twitter Header URL: https://freemytools.com/image-resizer/twitter-header/ Output: 1500×500 pixels, 3:1, file size under 5 MB. Specification verified 2026-08-05 against Third-party consensus; help.x.com blocks automated access (confidence: medium). A Twitter/X profile header is 1500×500 pixels at a 3:1 ratio — narrower than a Facebook cover and deeper than a LinkedIn banner, so nothing carries across between them. Like the others, the real constraint is what covers it: your profile picture sits over the lower-left, and on mobile the header crops in from the top and bottom rather than the sides. Why 1500×500: 1500×500 renders sharply across the range of widths X uses for headers without being large enough to trigger heavy compression. The 3:1 ratio is unusual and is the reason a repurposed Facebook cover always looks wrong here — at 2.7:1 it is close enough to seem like it should work, and far enough to visibly crop. Caveats: - Your profile photo overlaps the lower-left. Keep that corner clear. - Mobile crops the top and bottom, not the sides — the opposite of Facebook. Keep content vertically centred. - Keep the file under 5 MB; X compresses harder above that. - A 2.7:1 Facebook cover is not close enough to 3:1 to reuse. It will crop visibly. Questions this page answers: Q: What size is a Twitter header? A: 1500×500 pixels, a 3:1 ratio. It is displayed at various widths depending on the device, so supplying the full 1500×500 keeps it sharp everywhere. Files should stay under 5 MB. Q: Why is my Twitter header cropped? A: On mobile, X crops the header from the top and bottom rather than the sides. Keep important content vertically centred. On desktop, your profile photo also covers the lower-left corner. Q: Can I use my Facebook cover as a Twitter header? A: Not without resizing. A Facebook cover is 851×315 at roughly 2.7:1; a Twitter header is 1500×500 at 3:1. The ratios are close enough to look reusable and different enough to crop visibly. Resize properly instead. Q: What is the maximum file size for a Twitter header? A: 5 MB. Larger files are compressed more aggressively, which shows up first in text and logos. At 1500×500 a JPEG at 85% quality will normally land well under the limit. Q: Should my Twitter header be JPEG or PNG? A: PNG for graphics, logos, and text — it keeps edges crisp. JPEG for photographs, where it produces a much smaller file at the same visible quality. Both are accepted, and both should stay under 5 MB. --- ### Remove EXIF Data From JPG Without Uploading URL: https://freemytools.com/exif-remover/ Published: 2026-08-05 · Updated: 2026-08-05 Remove EXIF data from a JPG or PNG without uploading it anywhere.
