How to use it
- Choose your photo or drop it into the box.
- Keep 820 × 312, or type another width and height.
- Pick how the picture should fit, then download the result.
Why 820×312?
820×312 is a popular size for Facebook cover photos. Uploading the exact size avoids blurry automatic scaling and unexpected cropping by the website.
Choosing a fit mode: "Crop to fill" keeps the frame full and trims the edges, which is best for photos. "Fit inside" keeps everything visible, which is best for logos and screenshots. "Stretch" forces the shape and can distort faces, so use it only when you must.
Quality note: shrinking a picture keeps it sharp, but enlarging a small picture cannot add detail, so very small originals will look soft at large sizes.
Questions
How do I resize an image to 820×312 pixels?
Choose your picture, check that the size boxes show 820 and 312, and press the picture button. Then download the resized file.
What happens if my photo is not the same shape?
Pick a fit mode. "Crop to fill" cuts the extra edges, "Fit inside" keeps the whole picture and adds white bars, and "Stretch" changes the shape of the picture.
Is my image uploaded?
No. Resizing happens in your browser and nothing is sent to a server.
Can I use other dimensions?
Yes. Type any width and height in the boxes, up to 8000 pixels.
