Resize an image to 400×400
This page resizes your photo to exactly 400×400 pixels — the right size and dimensions for a profile avatar or app icon. Everything runs in your browser — your image is processed on your own device — and the on-screen preview is the same file you download, so the size is exact, never an estimate.
Resize an image to 400×400
- Open your image — drag it onto the tool, choose a file, or paste from your clipboard.
- It's preset to 400×400 — the width and height are already filled in for you.
- Check the preview — the before → after readout shows the exact new size and file weight.
- Download — save the resized image, ready to upload.
Tip: start big, then resize down
Resizing a large image down to 400×400 keeps it sharp. Enlarging a small image past its original size can't add detail, so begin with the highest-resolution copy you have.

Frequently asked questions
What size is 400 × 400?
400 × 400 is 400×400 pixels. This tool resizes your image to exactly that, for a profile avatar or app icon.
How do I resize an image to 400×400?
Drop your image above — the width and height are already set to 400 and 400. The resizing happens in your browser, and the preview is the exact file you'll download.
Will it lose quality?
Resizing down looks crisp and is effectively lossless to the eye. Re-encoding also strips EXIF/GPS metadata. If your source is smaller than the target, enlarging can look soft — start from the largest original you have.
