Image Format Converter FAQ
Do my images get uploaded?
No. Files are decoded, converted, previewed, and downloaded locally in your browser. Nothing is sent to a server.
Which formats can I convert between?
You can import PNG, JPEG, WebP, AVIF, and GIF files and export PNG, JPEG, WebP, AVIF, or GIF when your browser supports the target encoder.
What happens to transparency?
PNG, WebP, AVIF, and GIF can preserve transparency. JPEG has no alpha channel, so transparent areas are composited over the selected background.
How does it stay responsive with large files?
Inputs above 500KB are processed in a Web Worker so conversion work stays off the UI thread.
