Good to know
Which images can I convert?
Anything your browser can open: JPG, WebP, AVIF, GIF, BMP and PNG itself. Each image is decoded and saved again as a lossless PNG. Animated GIF and WebP files keep only their first frame.
Expect larger files
PNG stores every pixel exactly, so photos usually get several times bigger than as JPG, WebP or AVIF. Use PNG for logos, screenshots and images you plan to edit; for photos you just want to share, JPG is far smaller.
Does the PNG keep transparency?
Yes. Transparent areas of WebP, AVIF, GIF and PNG images stay transparent. JPG and BMP images have no transparency to keep.
Are my images uploaded?
No. The conversion runs inside your browser, so your images stay on your device. Files are only uploaded if you choose to optimize them with Arche, and those are deleted within 48 hours.
What is Arche?
Arche makes JPEG, PNG and WebP images smaller without changing their format or pixel size, and strips metadata such as EXIF location. It is free without an account; Pro raises the batch limits.
