Frequently Asked Questions

What are typical email attachment size limits?

Gmail: 25MB, Outlook: 20MB, Yahoo: 25MB, ProtonMail: 25MB. Many corporate email systems have even stricter limits (5-10MB).

Will recipients be able to open compressed PDFs?

Yes! Compression doesn't change the file format - it just optimizes the content. Any PDF reader can open compressed files.

What if my file is still too large?

Options: 1) Use maximum compression, 2) Split into multiple smaller files, 3) Use cloud storage links (Google Drive, Dropbox) instead of attachments.

How much can I reduce the file size?

Typically 40-70% reduction depending on your PDF content. Documents with many images compress more than text-only files.
