Blur Image
Apply an adjustable gaussian blur across a whole image.
What it does
Blur Image works on JPG, PNG, WEBP and HEIC images and writes a new file; the one you dropped in is untouched. Soften an image or hide detail.
When you need it
Usually because something downstream has an opinion: a profile photo that must be square, a marketplace that rejects anything over a certain width, a print that needs the right proportions, or a phone photo that arrived rotated.
Limits and caveats
Enlarging an image cannot add detail that was never captured, so scaling up softens it. Saving to a lossy format re-encodes the pixels, which is worth doing once rather than repeatedly on the same file. Everything happens in your browser, so the file never leaves your device.

Frequently asked questions
- Can I blur just one area?
- Not yet — this blurs the whole image. Pixelate works well for hiding details.
- Do my files get uploaded?
- No. This tool runs entirely in your browser, so the file never leaves your device.
