Image Tools
These tools use the browser's own canvas to decode an image, alter its pixels or its encoding, and write a new file. That means the formats available are the ones your browser can decode and encode, which in practice is PNG, JPEG and WebP.
Because the work happens on your device, large photographs are limited by memory rather than by an upload cap, and no copy of the image is kept anywhere after you close the tab.

How these tools behave
- Converting an image with transparency to JPEG flattens the transparent areas, because JPEG has no alpha channel.
- Compression is lossy for JPEG and WebP: re-compressing an already compressed image degrades it further.
- Face blurring uses a face-detection model served from this site, not from a third party.
Frequently asked questions
Which formats are supported?
PNG, JPEG and WebP. AVIF, HEIC and RAW camera formats are not supported, because they depend on decoders the browser does not reliably expose.
Does compressing an image twice halve the size again?
No. Lossy compression discards detail that cannot be recovered; a second pass mostly adds artefacts for very little further saving.
