How to resize an image for Facebook cover
- Select Choose files and pick your photo, or drop it on the box.
- The tool fills a 820×312 frame and trims equally from the longer side, so the middle of your photo stays. The file keeps the format of your original.
- Select Download and upload the result.
About the 820×312 size
A Facebook page or profile cover is a wide banner that is commonly published as 820×312 pixels for desktop at the time of writing. Phones crop it differently, so check how Facebook shows it before you finalise.
820×312 is a 205:78 landscape frame (width divided by height is 2.628) with 255,840 pixels, or 0.26 megapixels. At roughly 2.63 to 1 the cover is wide but not extreme. A landscape photo keeps most of its width and loses some height.
What happens to your photo
The table shows how common source images are treated when the tool fills 820×312.
| Source | Scaling | Part of the picture kept |
|---|---|---|
| 4000×3000 phone photo | reduced to 21 percent | 51 percent |
| 3024×4032 portrait photo | reduced to 27 percent | 29 percent |
| 1920×1080 screenshot | reduced to 43 percent | 68 percent |
| 1080×1080 square | reduced to 76 percent | 38 percent |
Sources smaller than the frame are enlarged because the output size is fixed, which can look soft. Platforms change their guidance over time, so check Facebook cover requirements before you publish.
Tips
- Keep faces and text near the centre. Phones show a narrower slice than desktop.
- Use a source at least 820 pixels wide, or the image is enlarged and soft.
- Large files upload slowly on mobile. Run the result through the image compressor if needed.
