Resize Image to 820×312
820×312 — Facebook's recommended cover-photo dimensions.
Facebook displays profile and page cover photos at 820×312 on desktop and 640×360 on mobile. Sticking to 820×312 avoids the awkward auto-crop you get from a mismatched aspect ratio.
The resizer pins the output to exact 820×312. Drop an image and the resizer applies the dimensions immediately.

Frequently asked questions
- What is 820×312 used for?
- Common uses: Facebook cover photos, banners with a strong horizontal aspect ratio. Pinning the output to exactly 820×312 avoids the auto-crop that platforms apply when the source aspect ratio doesn't match what they expect.
- Will the image get stretched?
- No. The resizer crops to 820×312 rather than stretching — the centre of the source image is kept and edges that don't fit the target aspect ratio are trimmed. For full control over the crop region, use the dedicated crop tool linked below.
- Is anything uploaded?
- No. The resize runs entirely in your browser using the Canvas API. Your image is processed and downloaded locally — nothing touches a server.
- What format does the output use?
- By default, the resized output uses the source format (JPEG in, JPEG out). Use the dedicated converter tools to change format afterwards — convert to WebP, JPG, or PNG depending on the destination.
- Can I resize to a custom dimension instead?
- Yes — the main resize tool lets you set any width and height, including non-standard sizes. This page is just a one-click preset for 820×312.
