Reduce PDF size — fit email and upload limits

Need a PDF small enough for Gmail (25 MB), Outlook (20 MB) or a portal that caps at 10 MB? Krymp reduces PDF size locally by re-encoding embedded images at a quality you pick. Preview the new size before downloading — and the file never leaves your browser.
