In short

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. Text and pages stay the same. If the file can't get any smaller, the try isn't counted.

## 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.

**Do I need Telegram Premium to use @PhotoToPdfMakerBot?**

No. @PhotoToPdfMakerBot works for everyone, with or without Telegram Premium. Free: 20 PDF actions and 10 document conversions a day.
