Shrink a PDF so it fits your email provider's attachment limit.
Temporarily unavailable
A program this tool depends on isn't available on the server right now, so it can't run. Other tools may still work — try the tool directory.
Most email providers cap attachments — Gmail at 25 MB, Outlook.com
around 20 MB, and many corporate mail servers lower still. A large, image-heavy PDF can
bounce or get rejected. This tool compresses the PDF by re-encoding its embedded images so it slips
comfortably under those limits while the text stays sharp.
Pick a quality preset, or set an exact target if your mail server is strict. If a file is still
too big after compression, splitting it or sharing a link is often better than forcing extreme
quality loss — see our guide on compressing files for
email. Files are processed privately and deleted right after.
Frequently asked questions
What size should I aim for to email a PDF?
Under your provider's limit with headroom — for Gmail's 25 MB, aiming for well under that is safest since encoding adds overhead. For strict corporate servers, try a few MB. You can set an exact target in the box.
Will compressing make the text blurry?
No — only embedded images are re-encoded; text and vector graphics stay crisp. Heavy compression mainly softens photos and scans.
My PDF is still too large — now what?
Lower the target or the maximum image dimension, split the document into parts, or share it via a cloud link instead of an attachment. Forcing a huge scan to a tiny size rarely looks good.
Is it safe and private?
Your file is uploaded over HTTPS, processed on our server, and the upload is removed right after. The generated result is cleaned up automatically by a periodic job. We never share your files and no account is needed. See our Privacy Policy.
