Are my images uploaded?
No. The conversion happens inside your browser with the Canvas API, so your pictures never leave your device.

Frequently asked questions
What happens to transparent areas?
PNG, WebP and GIF keep transparency. JPG and BMP do not support it, so transparent pixels are filled with the background color you choose.
Is there a limit on the number of files?
No fixed limit. Very large batches are only limited by your device's memory.
