How to Resize Images for Social Media — All Platform Sizes (2026)
Every social media platform has its own preferred image dimensions. Upload the wrong size and your image gets cropped, stretched, or re-compressed into a blurry mess. This guide lists the correct dimensions for every major platform and shows how to resize any image to fit — for free, in your browser.
Why Image Dimensions Matter on Social Media
Social media platforms do not simply display images at any size — they fit images into fixed display areas determined by their interface layout. If your image does not match that area's aspect ratio, the platform either crops it (cutting off parts of the image), letterboxes it (adding bars around it), or stretches it (distorting the content).
Beyond aspect ratio, platforms also re-compress uploaded images to reduce bandwidth. Starting with the correct dimensions means less re-processing and better final quality. A 5,000-pixel-wide image that gets scaled down to 1,080 pixels by Instagram will be compressed more aggressively than one you already sized to 1,080 pixels before uploading.

How to Resize to the Right Dimensions
- 1
Open the image resizer
Go to the free image resizer tool. No account required — the tool works in your browser and nothing is uploaded to a server.
- 2
Upload your image
Drag and drop your photo or click to select it. The tool accepts JPG, PNG, and WebP files.
- 3
Enter the target dimensions
Type the width and height in pixels from the table above. Enable the aspect ratio lock if you want to scale proportionally, or disable it to set exact dimensions.

Download and upload to the platform
Download your resized image and upload it directly to the social media platform. No more unexpected cropping.
Tips for Better Social Media Images
- Always start with the largest version
- Resize down from a large original rather than resizing up from a small one. Scaling up creates a blurry, pixelated result.
- Compress after resizing
- Resize to the correct pixel dimensions first, then compress to reduce file size. This order gives the best quality result.
- Use PNG for graphics, JPG for photos
- Profile photos and thumbnails with text benefit from PNG quality. Natural photos upload faster as JPG.
- Keep safe zones for profile crops
- Profile photos are often cropped to a circle. Keep faces and important content in the centre third of the image.
- Test on mobile before publishing
- Banner and cover images look different on desktop vs mobile. Check on both before going live.
- Re-upload if quality looks poor
- If a platform re-compresses your image heavily, try uploading a version that is closer to the platform's display size to reduce the compression ratio.
