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
Will JPG to PNG improve quality?
No. PNG will preserve the pixels from the JPG, but it cannot restore detail already lost in the JPG.
Is the image uploaded?
No. The conversion runs locally in this browser tab.
Why is the PNG larger?
PNG is lossless, so a photo saved as PNG is often larger than the original JPG.
