About this tool
Gmail and Outlook.com reject attachments over 20–25 MB, many company and government mail servers stop at 10 MB or less, and the recipient’s mailbox may be stricter still. This page aims for 5 MB, which gets through almost everywhere. Images are compressed first so the text stays sharp and selectable; pick a smaller limit if your mail server needs it.

Frequently asked questions
What is the attachment limit for Gmail and Outlook?
Gmail allows 25 MB per email and Outlook.com 20 MB, counting all attachments together. Company servers often allow less, so a smaller file is safer.
Should I zip the PDF instead?
Zipping saves very little because PDFs are already compressed. Compressing the images inside the PDF shrinks it far more, and the recipient can open it directly.
Are my files safe?
Yes. There is no server that receives your files; everything is processed in your browser and stays on your device. You can confirm it in the Network tab of your browser’s developer tools.
Is it really free?
Yes. Every tool is free with no daily limits, no sign-up and no watermark on your files.
Does it work on phones?
Yes, it works in any modern mobile or desktop browser, and you can install it as an app from the browser menu.
