FAQ

Image Tools — frequently asked questions

Which image formats can I convert?

The converter supports WebP, PNG, JPEG, AVIF, SVG, and the Netpbm family (PGM, PPM) plus BMP. Compression and resizing accept any browser-supported image format.

Does image compression reduce quality?

You control the quality with a live slider and see the resulting size before downloading. Values around 70-80% are usually indistinguishable from the original to the human eye.

Are my images uploaded to a server?

No. Every image tool here processes files locally in your browser — nothing is uploaded, including for batch compression and conversion.
