What Filee does for PNG → WEBP
WebP is ideal for websites: photos get much smaller than JPG and graphics keep their transparency. The WEBP preset saves at quality 85, a good balance for the web.
- Built in: works right after installing Filee, with nothing else to download.
- Engine: ImageMagick.
- Adjustable quality for JPG, WEBP and AVIF: JPG saves at 90 % by default, and a JPG 70 % preset makes smaller files.
- Resize while converting, by percentage (for example half size) or to a maximum long edge.
- Batch: one file or hundreds, converted in parallel; a failure never stops the rest.
- Private: files are converted on your PC and never uploaded, even without internet.
- Saved next to the original, or in a folder and with a file name pattern you choose.
