Sample workflow: choose a JPEG, PNG, WebP, or GIF on this device, then Process.

An avatar that should look like the CSS, but the destination only accepts a flat image. CSS radius is still better on the web.

A marketplace that wants a “soft” thumbnail but has no CSS. This page masks pixels. On the web, border-radius is still the right tool.

Square first: cropper. Smaller file: compressor. Watermark: image watermark.

Icons, not ID-photo specs

Rounded avatars and a thin border are cosmetic. Passport and visa photo sizes are the cropper and resizer plus the agency’s PDF. JPEG will flatten transparency so corners may go white. Favicon sizes are a different generator (32 / 180 / 192 / 512).

How to use it

  1. Drop a photo. Prefer PNG out if corners must be transparent.
  2. Set the radius. Download.
  3. Check the destination background color if you used JPG.

FAQ

Why did the corners turn white?

JPEG has no alpha. Use PNG, or pick a fill that matches the destination background.

True circle avatar?

Only if the source is square and the radius is half the side. Crop to square first if needed.

Can I keep CSS instead?

Yes, and you should on a site you control. This page is for hosts that flatten images.

Is this a collage?

No. One image. Tiles are the collage tool.

Is the image uploaded?

No. About 32 MB typical.
