FAQ
What formats can I use?
JPG, PNG, WebP, GIF, BMP โ all the usual suspects. If your camera or phone can save it, we probably handle it.
Are my images uploaded anywhere?
Never. Everything happens inside your browser. Your photos stay on your device.
Is there a file size limit?
For the smoothest experience, keep images under 10 MB. Larger files usually work too, just might take a moment longer.
Can I process multiple images at once?
One at a time for now, but batch mode is on our roadmap.
Will my images lose quality?
For conversions, you control the quality slider. We default to a sweet spot between size and clarity.
Does it work on phones?
Yes โ and you can pick images straight from your camera roll.
