Social Media Image Resizer
One photo, every platform — exact sizes for Instagram, X, YouTube, link previews and more.
Every platform wants a different image shape: Instagram feeds like 1080×1080 or 1080×1350, stories need 1080×1920, YouTube thumbnails are 1280×720, and a link shared anywhere pulls a 1200×630 Open Graph image. Upload the wrong shape and the platform crops it for you — usually straight through someone's face. This tool resizes any image to the exact dimensions of nine common formats, with you in control of how it fits.
Two fit modes cover every case: Fill scales the image to cover the whole frame and crops the overflow evenly from the edges (best for photos), while Fit shrinks the entire image into the frame and pads the rest with a color you choose (best for graphics, screenshots and logos where nothing may be cut off). The preview shows the final result before you download it as JPG or PNG. Processing is local — unpublished campaign assets never leave your browser. Need a crop positioned somewhere other than center? Do a precise cut with the crop tool first, then resize here.
How to use the Social Media Image Resizer
- Drop your image onto the tool.
- Pick the platform preset — Instagram post/story, X, YouTube thumbnail, Open Graph, LinkedIn, Pinterest or Facebook cover.
- Choose Fill to crop to the frame, or Fit to pad the image with a background color instead.
- Check the preview and click Download. Repeat with another preset for the next platform — the image is already loaded.
Frequently asked questions
What size should an Open Graph (link preview) image be?
1200×630 pixels (a 1.91:1 ratio) is the safe standard — Facebook, LinkedIn, Slack, Discord and iMessage all render it well. It's the image your og:image meta tag should point to.
Should I use Fill or Fit?
Fill for photographs — it covers the frame edge-to-edge and trims the sides evenly, which usually looks natural. Fit for anything with text, logos or UI screenshots, where cropping would cut off content; you pick the padding color that surrounds it.
The crop cut off the important part of my photo. What can I do?
Fill crops from the center outward. If your subject is off-center, first cut the image to roughly the right ratio with the crop tool (which lets you position the box anywhere), then run it through the preset here for exact dimensions.
Which format should I download — JPG or PNG?
JPG for photos: platforms re-compress uploads anyway, and JPG keeps files small. PNG for graphics with text or sharp edges, where JPG artifacts are visible — YouTube thumbnails with big text often look better uploaded as PNG.
Are the platform sizes up to date?
The presets reflect each platform's current recommended upload sizes. Platforms occasionally change specs, but they scale good-quality uploads gracefully — an exact-ratio image at these resolutions will always render cleanly.
