Frequently asked questions
Are my photos uploaded?
No. The conversion runs on a canvas in your browser, and your photos never leave your device.
What is the difference between Natural and Flat?
Natural weights red, green and blue the way the eye perceives brightness (Rec. 709), so greens come out lighter and blues darker, as in a classic black-and-white photo. Flat takes a plain average of the three channels, which can look duller.
How do I make a scanned document or signature pure black and white?
Choose Pure B/W and adjust Threshold (1–254). Pixels brighter than the threshold become white and the rest black, so raise it if faint text disappears and lower it if the paper shows black specks.
Is the result a true grayscale file?
The pixels are gray, but the image is saved as a normal JPG, PNG or WebP with color channels, not as an 8-bit or 1-bit grayscale file.
Is transparency kept?
Yes, when you save as PNG or WebP; Same as input keeps PNG files as PNG. JPG has no transparency, so transparent areas become white.
Which format do HEIC or GIF files get?
With Same as input, JPG, WebP and AVIF keep their format, while HEIC, GIF, BMP and other files are saved as PNG. Animated GIFs are processed from their first frame only.
