About Compress PDF
Large PDFs are hard to email, upload to government or university portals, or send on WhatsApp. MyPDF Compress PDF shrinks your file by re-encoding images and removing unused data, while keeping text sharp and searchable. Choose Basic for everyday documents or Strong when you need the smallest possible file.

Frequently asked questions
How much smaller will my PDF get?
It depends on the file. PDFs with many photos or scans often shrink by 50–90%. Files that are mostly text are already small and may not shrink much.
What is the difference between Basic and Strong?
Basic keeps images sharp enough for reading on screen. Strong makes the file as small as possible by lowering image quality further.

Are my files safe?
Your PDF is sent over an encrypted connection, processed automatically and deleted from our server within 1 hour.

Does it work on my phone?
