Frequently asked questions
Can it crack an unknown password?
No. You need the open password; FlashFile only removes protection from files you can already open.
Is the Unlock PDF tool free?
Yes. It is completely free, with no sign-up, no watermark and no daily limit.
Are my files uploaded to a server?
No. FlashFile processes your files entirely inside your browser, so they never leave your device.
Is there a file size limit?
There is no fixed limit. Files up to about 200 MB work on most computers; very large files depend on your device memory.
