Frequently asked questions
Is Flatten PDF free to use?
Yes. Every tool on Pdflify is free and needs no account.
Is my file uploaded anywhere?
No. This tool reads and rewrites your file inside your browser tab using JavaScript, so the document itself never leaves your device.
Does it work on a phone?
Yes. The workspace is responsive and works with touch, though very large files depend on your device's memory.
What if my PDF is password protected?
Encrypted files cannot be opened in the browser. Open the file with its password in your PDF reader, save an unprotected copy, then try again.
