Image Format Converter — Frequently Asked Questions

What is AVIF and why use it?

AVIF is a next-generation image format based on AV1 video codec. It offers about 50% smaller file sizes than JPEG at the same quality. It is supported in Chrome 85+, Firefox 93+, and Edge 85+.

What is the difference between lossless and lossy WebP?

Lossless WebP preserves every pixel of the original — no quality loss, but larger files. Lossy WebP uses compression to reduce file size, with adjustable quality. Toggle Lossless WebP on when you need pixel-perfect output.

Can I convert SVG to PNG?

Yes. Just upload your SVG file and select PNG (or JPG/WebP/AVIF/BMP) as the output format. The SVG will be rasterized on a canvas at its native dimensions.

Does JPG support transparency?

No, JPG does not support transparency. If your source image has transparent areas (PNG, GIF, WebP, or SVG), the converter will fill them with the background color you choose. White is the default.

What quality setting should I use?

For Web use, 80-92% offers a good balance between quality and file size. For archival purposes, use PNG or Lossless WebP (lossless). The presets — Maximum (100%), Excellent (92%), Good (80%), Standard (60%), and Minimum (30%) — help you choose quickly.

Are my images uploaded to a server?

No. Everything runs locally in your browser using the Canvas API. Your images never leave your device.
