About Compress PDF

Compress PDF offers two different trade-offs. Basic rewrites the PDF structure and removes metadata while preserving selectable text. Smart renders pages as JPEG images, which can reduce size but removes text selection and can affect links, forms, and accessibility. Keep the original and inspect the result before sharing. Processing takes place in your browser.

Compress PDF — Frequently Asked Questions

How much can TinyPDFs compress a PDF?
Savings depend on the original document and settings; there is no guaranteed percentage. Already optimized PDFs may become larger. Compare the original and output sizes shown after processing.
Will compression blur my images?
Smart mode rasterizes every page. Lower quality settings may blur images and small text, and text is no longer selectable. Basic mode preserves text selection but may achieve little reduction.
Is there a PDF size limit?
Available device memory limits processing. Large or image-heavy files can fail, especially on phones. Try a smaller document and keep the original if processing fails.
Is it free and safe?
Yes. It’s free with no sign-up, and the compression runs locally — your PDF never leaves your device.
