Compress PDF to 1 MB
A 1 MB limit is common on portals and small enough for any email. Many documents reach it with little visible change.
Rebuilds your PDF as compact images so it lands under the size you need. Best for scanned documents and photos; text won't stay selectable.

When to keep your original
If your PDF has selectable text and is close to 1 MB, it may be better to export it again from Word or Google Docs with a smaller size setting. That keeps the text selectable. Use this page for scans and for files you can't export again.

Frequently asked questions
Is my file uploaded?
No. Everything runs inside your browser, on your device. Nothing is sent to a server, so private documents stay private.
Why can't I select the text afterwards?
To guarantee the size, each page is rebuilt as an image. Text can no longer be selected or searched, and form fields and links are lost. Scanned documents lose nothing, because they are already images.
What if my PDF is already small enough?
The tool tells you and offers your original file unchanged, so text stays selectable.
Is it free?
Yes, with no watermark and no sign-up.
