About the bot

Frequently asked questions
Is it free?
Yes. A merge counts as one of the 20 free PDF operations a day.
In what order are the pages?
In the order you sent the files; pages inside each file stay as they were.
One of my PDFs has a password. Will it work?
No. The bot can't open password-protected PDFs: remove the password and send the file again.
Can I make the merged PDF smaller?
Yes. Send it to the bot on its own and tap 🗜 Compress this — the bot shrinks the images inside.
