Frequently asked questions

Are my files uploaded?
Your files are processed on your device and are never uploaded to any server.
Does it work on my phone?

Will the quality go down?
Stronger compression turns pages into images, so text may look slightly softer. Use the lighter setting if you need crisp text.
