Compress a PDF so you can email it
Get under the attachment limit without uploading your file anywhere.
Most email providers reject attachments over 20 to 25 MB, and a single photo-heavy PDF can blow past that easily. Shrink it here first. The compression runs in your browser, so the document is never uploaded, and you can see exactly how much smaller it gets before you download.

Why compress before emailing, privately?
The documents you email are often the private ones: contracts, reports, scans. Compressing them locally means you solve the size problem without first handing the file to a compression service.
Frequently asked questions
How small can it get?+
It depends on the file. Scanned and image-heavy PDFs shrink the most with the stronger levels.
Will the text still be readable?+
The light level keeps text crisp and selectable. Stronger levels trade some sharpness for a much smaller file.
Is my file uploaded to compress it?+
No. Compression happens in your browser, so the file never leaves your device.
Is it free?+
Yes, with no sign-up.
