Social Media Image Size Tools
Every social media platform has its own image dimension requirements — and they change frequently. Using the wrong size can result in images that are cropped, stretched, blurry, or visually off. These tools resize your images to the exact pixel dimensions each platform recommends.
Why Image Dimensions Matter on Social Media
Social platforms re-process uploaded images to fit their display grids. If your image is the wrong aspect ratio, the platform will crop it — sometimes removing important parts of the composition. If it is too small, the platform may upscale it, producing blurry results. Uploading at the correct native size gives you full control over what gets shown.
Platform Image Size Reference
| Platform | Image type | Recommended size |
|---|---|---|
| Profile photo | 170 × 170 px | |
| Cover photo | 851 × 315 px | |
| Shared image | 1200 × 630 px | |
| Square post | 1080 × 1080 px | |
| Portrait post | 1080 × 1350 px | |
| Story | 1080 × 1920 px | |
| Twitter / X | Profile photo | 400 × 400 px |
| Twitter / X | Header image | 1500 × 500 px |
| Twitter / X | In-stream image | 1600 × 900 px |
| Pin image | 1000 × 1500 px | |
| YouTube | Channel art | 2560 × 1440 px |
| YouTube | Thumbnail | 1280 × 720 px |
These sizes are correct as of early 2026 but may change as platforms update their display systems.
Tips for Social Media Images
Use the highest quality source you have. Resizing down from a larger original always produces better results than scaling up from a smaller one. Start from the original photo or export, not from a previously compressed version.
Save as JPG for photographs, PNG for graphics. Photos compress well as JPG without visible quality loss. Graphics with text, logos, or flat colours look sharper as PNG because JPG compression introduces artefacts around edges and text.
Check cropping on mobile. Profile photos are displayed as circles on most platforms. Make sure your subject is centred so it isn't cropped by the circular mask.
Frequently Asked Questions
Why does my profile photo look blurry after uploading?
Blurriness usually means the uploaded image was smaller than the platform's display size, causing it to be upscaled. Upload at or above the recommended resolution for your platform.
Should I upload images at exactly the platform's dimensions, or larger?
Uploading at exactly the recommended dimensions is ideal. Uploading somewhat larger (up to 2× the display size for retina screens) is also fine — the platform will downsample it. Uploading smaller than the display size will always risk blurriness.
Do these tools upload my images to a server?
No. All resizing is done by your browser using the Canvas API. Your images are never sent anywhere.
