Compress PDF to 1 MB

Make a PDF smaller than 1 MB for email or an upload form. The file stays under 1,000,000 bytes, so it passes however the website counts.

Before you start

A limit of 1 MB is common on upload forms and for email attachments. Big scans, colour photos pasted into documents and PDFs saved from phone apps are the usual reasons a file goes over.

Websites count 1 MB in two ways: 1,000,000 bytes or 1,048,576 bytes. SafeResize keeps your file under 1,000,000 bytes, which passes both.

Tips

Questions and answers

Does 1 MB mean 1,000 KB or 1,024 KB?

It depends on the website. SafeResize aims for under 1,000,000 bytes, so the file is accepted under either rule.

Can I compress a PDF with a password?

A PDF that needs a password to open cannot be changed here. Open it in your PDF app, save a copy without the password, then try again.

Is there a page limit?

No fixed limit, but very long PDFs take more time and memory, especially on older phones.
