Common questions

Image Format Converter FAQ

Which image formats are supported?+

JPG, PNG, WebP, and AVIF are available as output formats. JPG, PNG, WebP, GIF, and BMP files generally work well as browser-supported inputs.

Does converting to WebP reduce quality?+

WebP is a modern format that often produces smaller files than JPG while preserving equal or better visual quality at similar settings.

Can I convert multiple images at once?+

Yes. You can drag in multiple files, pick one output format, and convert them all in one run.

Why can I not select the same format?+

When all selected files share the same format, that output option is disabled to prevent no-op conversions.

Will transparency be preserved?+

Transparency is preserved when converting to PNG or WebP. Converting to JPG will replace transparency with a white background.
