Why compress PDF under 25MB?
The 25MB Gmail attachment limit is something almost everyone hits eventually. Reports, presentations, portfolios, and multi-page scanned documents routinely exceed this limit. Rather than switching to Google Drive links (which recipients sometimes can't access), just compress the PDF to fit. AskPDF makes this a 10-second process.
