Compress PDF for Email: what you need to know
Email services cap attachment sizes — Gmail allows 25 MB and Outlook.com 20 MB, and many work mail servers allow even less. A large scanned contract or photo-heavy report can easily exceed that. FilesForU opens this page with Strong compression selected, which gives the biggest reduction for scans and photos.
Text stays sharp because only images are recompressed. If the file is still too large, split it into two PDFs with Split PDF and send them separately.

Questions & answers
What size should a PDF be for email?
Under 10 MB is safe for almost everyone; Gmail accepts up to 25 MB and Outlook.com up to 20 MB.
Will the person receiving it notice lower quality?
Text and lines look the same. Photos are slightly softer on Strong, which is rarely noticeable on screen.
What if it's still too big?
Use Split PDF to divide it into parts, or remove pages you don't need with Remove Pages.
Are my files uploaded to your server?
No. This tool runs entirely inside your browser, so your files stay on your device. FilesForU never receives, stores or sees them.
Is it really free?
Yes. Every tool is free with a free account — no daily limit, no watermarks, and files up to 500 MB.
