Compress PDF for Gmail

Shrink a PDF before you attach it in Gmail. Gmail rejects attachments over 25 MB. This page starts on our smallest setting. We do not send the email for you.

How to compress a PDF for Gmail

  1. Choose the PDF you want to attach, or drop it into the tool.
  2. Add more files or rotate pages if you need to, then open compression levels.
  3. Leave Extreme compression selected for the smallest attachment, or pick balanced quality.
  4. Download the smaller PDF and attach it in Gmail. Server copies are deleted after 60 minutes.

Features

Built for Gmail's 25 MB cap

The job is the same Compress PDF compressor. This page starts on the smallest setting because Gmail blocks attachments larger than 25 MB.

We do not send mail

You download the file and attach it yourself. MyPDF does not connect to your Gmail account.

Still too large?

A long scan can stay over 25 MB even at Extreme. Split the PDF or use a Drive link instead of an attachment.

Deleted after 60 minutes

We keep the upload and the result only long enough for you to download them.

No watermark

The file you attach does not get a MyPDF stamp. Free accounts get 5 jobs a day.

Other inboxes

Outlook and most providers use a similar 20–25 MB range. Compress PDF for email is the generic version of this page.

Make a PDF small enough for Gmail

Gmail's attachment limit is 25 MB per message. That is why people land here. MyPDF compresses the file with Ghostscript on the server, then you download it and attach it in Gmail. We do not send the email and we do not ask for Google account access.

This page pre-selects Extreme compression (level 3). That is the smallest quality we offer. A presentation with photos may still be large. If it is, split the PDF or share a Drive link instead of an attachment.

Working files are deleted after 60 minutes. There is no watermark. Free accounts get 5 jobs a day. If the original is over 25 MB, use Pro, Team, or a $5 day pass before you upload.
