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
How does JPG compression work?
The browser re-exports the image at a lower quality setting, which usually reduces file size.
Can I target an exact size?
Not in v1. Use the output size comparison and adjust quality if needed.
Is the JPG sent to a server?
No. Compression runs locally in this browser tab.
