Compress PDF to 1 MB

Under 1 MB clears most email attachment limits and web forms while leaving plenty of headroom for image quality.

How to do it

Upload your PDF.

Pick the Recommended level (Strong for very large files).

Download the compressed PDF, now under 1 MB.

Most everyday PDFs drop under 1 MB at the Recommended level with no visible change. Only long, image-dense documents need the Strong level.

Is 1 MB enough for email?

Yes. Most mail providers allow attachments of 10 MB or more, so a sub-1 MB PDF sends without trouble.

Do I lose quality?

At the Recommended level the change is not visible on screen. The text layer is never altered.

Any watermark or sign-up?

Neither. The tool is free to use.

How long are files kept?

They are deleted automatically about an hour after compression.
