Why do email and portals limit PDFs to 1MB or 2MB?
Small attachments keep inboxes and government servers fast. A scanned PDF from a phone app can easily be 10MB or more, so it needs compressing first.
How long does it take?
A few seconds for most files. Very long PDFs with 50 or more pages can take longer on older phones.

Questions people ask
Can I compress a 20MB PDF to 1MB?
Often yes, if it is a scanned document. Try it and see; the result shows the final size.
Is it free?
Yes.
Is my PDF uploaded?
No. It is processed on your device.
How much smaller will my PDF get?
Scanned PDFs and PDFs full of photos often shrink by 50 to 90 percent. PDFs that are mostly typed text are already small, so they shrink less.
Will the text stay sharp?
Recommended keeps text easy to read on screen and in print. Extreme makes the file much smaller, but fine print can get soft, so check it before you upload.
