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
Why is PNG hard to compress?
PNG is lossless. For photos or screenshots, WebP or JPG can be much smaller.
Will transparency remain?
PNG keeps transparency. WebP can also keep transparency in modern browsers.
Does this upload the PNG?
No. The selected PNG is processed locally.
