About This Tool
Ten megabytes is the invisible wall of corporate life - Outlook attachments, expense systems, legal portals, and client uploads all cap out around there, and a design-heavy PDF sails past it without trying. Unlike brutal downsampling, hitting 10MB rarely costs visible quality: Low or Medium compression trims the fat while the document looks identical. This tool gets any PDF under 10MB in your browser, no signup, no watermark.

Frequently Asked Questions
Why do corporate systems cap attachments at 10MB?
Mail servers and document systems cap attachments to control storage and bandwidth across thousands of users. Ten megabytes is the most common corporate ceiling.
Will my slide deck still look sharp under 10MB?
Almost always. Decks compress well because slides repeat fonts and graphics; charts and photos stay crisp at Low or Medium compression.
What if my PDF is hundreds of megabytes?
Start with Medium, then High if needed - image-heavy files drop 80-90%. For multi-hundred-megabyte manuals, consider splitting chapters with the Split PDF tool as well.
