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
What kind of watermark can I add?
The first version supports text watermarks with opacity, size, single placement, and tiled mode.
Can I watermark private drafts?
Yes. The image is processed locally and is not uploaded to ImageToolDeck.
Can the watermark be removed later?
The downloaded output has the watermark drawn into the pixels. Keep your original file separately.
