Local processing
Your selected file is read by the browser and processed with Canvas or a small lazy-loaded library. ImageToolDeck does not upload the file to a processing server.
Honest limits
Very large images can hit browser memory or canvas size limits. HEIC and WebP support depends on the browser. JPG output cannot preserve transparency.
Questions
Does PNG to WebP keep transparency?
Modern browsers can export WebP with transparency for many images.
Is this processed on a server?
No. Canvas exports the image inside your browser tab.
When should I keep PNG?
Keep PNG for exact graphics, screenshots, or compatibility with apps that do not accept WebP.
