Frequently asked questions
- Are my images uploaded anywhere?
- No. Conversion happens locally in your browser using Canvas.
- Why is the JPEG larger than the PNG?
- PNG is lossless and can be smaller for flat graphics; lower the quality slider for smaller JPEG or WebP files.
- Does WebP work in every browser?
- WebP encoding works in all modern browsers; if unsupported, choose PNG or JPEG instead.
