how to compress pdf for email
- drop the pdf you want to email.
- keep the 5 mb target, or pick a smaller size if you are attaching several files.
- press compress pdf, then download the result.
- attach the downloaded file to your email as usual.
gmail allows 25 mb per email, outlook.com 20 mb, and many company mail servers only 10 mb. the limit covers the whole message, and attachments grow by about a third when they are sent, so a 19 mb pdf can still bounce from a 25 mb inbox.
we start this page at a 5 mb target, which gets through almost every mail server and is quick to download on a phone. if you are sending several files, set a smaller target for each one so they fit together.

frequently asked questions
what size should an email attachment be?
under 10 mb is safe for nearly every inbox, and under 5 mb is friendly for people reading on phones. the 5 mb default on this page works almost everywhere.
gmail says my file is too big, will this fix it?
yes, as long as the pdf is mostly scanned pages or images, which is the usual reason for large files. compress it to 5 mb or less and attach it again.
is this safer than an online compressor?
your pdf never leaves your computer: the compression runs in your browser. upload-based sites copy your document to their servers.
