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
Is WebP smaller than JPG?
Often yes, but the final size depends on the image and quality setting.
Does the file upload?
No. The JPG is converted locally in the browser.
Can every app open WebP?
Modern browsers can, but some older apps still prefer JPG or PNG.
