Pick a platform, upload your image, and download it at the right size. Instagram, Reels, YouTube thumbnail, Pinterest and more.
The Social Media Image Resizer is a free online tool that resizes any image to the right size for Instagram posts, Reels, YouTube thumbnails, Pinterest pins, Facebook and LinkedIn. Pick a platform, upload your image, choose fill or fit and download it. It is made for designers and creators, and it runs in your browser.

Every platform crops images in its own way. Post a landscape render on Instagram and the sides get cut. Post a square on Pinterest and it gets lost in the feed. Using the right size from the start keeps your work looking sharp.
For Instagram, portrait 4:5 takes more space in the feed than a square, so it gets more attention. For Reels and Shorts, 9:16 is the only size that fills the screen. Pinterest likes tall 2:3 pins.
Fill crops the edges so the image covers the whole frame. Fit keeps the full image and adds a background color around it. Use Fit for renders where nothing should be cut, like a full room or a product.
1080 x 1350 px (4:5 portrait). It shows bigger in the feed than a square post.
1280 x 720 px, 16:9 ratio, under 2 MB.
No. Resizing happens in your browser and the file stays on your device.
The table on this page lists every size the tool supports, so you can also use it as a quick size guide.
Use it before you post a render, a product photo or a design on social media. It is most useful when one image needs to go to several platforms: make a 4:5 version for Instagram, a 9:16 version for Reels and Shorts, and a 2:3 version for Pinterest, all from the same file.
Tip: keep important text and faces away from the edges. Many apps cover the top and bottom of Stories and Reels with buttons and captions.
Making an image bigger than its original size can soften it. Start with the largest version of your image you have.
PNG keeps full quality. If a platform has a file size limit, you can convert it to JPG afterwards.
Use Fit when nothing should be cut, like a full room or a product. Use Fill when the edges are not important.
Not yet. It works on one image at a time. Pick the size, add the image and download, then repeat.
Writing the text for your pin too? Try the Pinterest Pin Title & Description Generator. Need the visuals themselves? See graphic design or AI product video.
