Frequently asked questions
What's a safe size for email attachments?
Most providers cap attachments around 20-25MB (Gmail is 25MB), but many corporate inboxes are stricter — 10MB is a safe target if you're not sure.
Can I combine multiple files before compressing?
Yes — add them all, they'll merge into one PDF before compressing to your target size.
Does this tool email the file for me?
No — it only compresses. Download the result and attach it to your email as usual; nothing is uploaded in between.
