To compress a PDF on your phone, send the PDF on its own to the free bot @PhotoToPdfMakerBot and tap 🗜 Compress this — the bot shrinks the images inside and sends back a smaller PDF, showing the size before and after.

Frequently asked questions
How much smaller will my PDF get?
It depends on the pictures inside: scans and photos shrink a lot, a PDF that is only text barely changes.
My PDF is over 20 MB. What can I do?
Bots in Telegram can download files only up to 20 MB, so split the PDF first or export it again with smaller images.
Can I compress a PDF I just made from photos?
Yes. If the finished PDF is heavier than 5 MB, the bot shows 🗜 Compress this right under it.
Is my file stored?
No. It is processed on our server and deleted after the reply.
