Questions
Is Convert images really free?
Yes. Every Sheetfold tool is free with no sign-up, no watermark and no limit on how many files you do.
Are my files uploaded?
No. The work happens inside your web browser on your own device. Your files are never sent to Sheetfold or anyone else, and we can't see them.
Does it work on my phone?
Yes. Sheetfold works in modern browsers on iPhone, Android, Mac, Windows and Chromebook.
Is there a file size limit?
There's no set limit. Very large files (hundreds of MB) depend on how much memory your device has.
