Social media image sizes, all in one place
Every network crops pictures differently. Upload a landscape photo to an Instagram Story and heads get cut off; post a tall image as a YouTube thumbnail and it gets black bars. This resizer has the recommended upload size for each format built in. Choose a preset, drag the photo to frame the important part, and download a file that fits exactly. You can also export every size for a platform at once as a ZIP.
How to resize an image for social media
- Drop a photo above or paste it with Ctrl+V.
- Choose the network, then the format — for example Instagram → Portrait post.
- Leave Fill (crop) on and drag the photo to frame it, or pick Fit + blur to keep the whole picture with a soft blurred background.
- Download as JPG for photos or PNG for graphics with text.

Networks change their layouts from time to time, but these sizes are safe starting points: they are large enough to look sharp and use the ratio each feed displays.
Tips for better-looking posts
- Portrait (4:5) beats square on Instagram — it takes up more of the screen as people scroll.
- Keep text and faces away from the edges of Stories and Reels, where app buttons cover the picture.
- Profile photos are shown as circles, so centre the face and leave space around it.
- For YouTube thumbnails, use big, high-contrast text; add it with the watermark tool. Need a custom shape? Use the image cropper.
Frequently asked questions
What size should an Instagram post be?
1080 × 1350 pixels (4:5 portrait) gives the biggest post in the feed. Square posts are 1080 × 1080 and Stories and Reels are 1080 × 1920.
What is the YouTube thumbnail size?
1280 × 720 pixels, a 16:9 ratio. Keep the file under 2 MB; the JPG option here usually produces a file far smaller than that.
How do I stop my photo being cropped on social media?
Resize it to the exact size of the format before uploading. If you want to keep the whole photo, choose Fit + blur or Fit + white so nothing is cut off.
Can I resize one photo for every platform at once?
Yes. Choose a platform and press Download all sizes to get every format for that network in a ZIP file.
Does resizing reduce quality?
Not noticeably. Images are scaled with high-quality smoothing and saved at high JPG quality. Start with a photo at least as large as the size you need for the sharpest result.
Are my photos uploaded?
No. Everything happens in your browser, and your photos are never sent to a server.
