PDF Compressor
Make PDFs small enough for email, WhatsApp and form uploads. Compress many files, hit an exact size limit, then download as PDF or ZIP

Up to 20 files. Everything stays on your device.
- Light: keeps text selectable and recompresses photos gently. Best for documents you will print
- Balanced: keeps text and shrinks large photos more. A good default for email
- Strong: turns every page into an image. Use it for scanned documents. Text will no longer be selectable or searchable
- Target size: for portals with a limit such as 200 KB or 1 MB. It tries gentler settings first and stops when the file fits
- If the result is not smaller, your original file is returned, so you never get a bigger file
- A PDF with only text is already small. Strong can even make it bigger
- Compress several files at once and download them together as a ZIP
- Password protected PDFs must be unlocked first
- Very large files take time on phones. Use Cancel if you want to stop

PDF Compressor FAQ
It reduces PDF file size significantly while trying to keep the document readable.
- Upload your PDF.
- Choose the compression level if offered.
- Start compression.
- Download the smaller PDF.
Text stays readable, but images inside can look softer at higher compression. Keep your original file in case you need full quality later.
Some PDFs are already optimized, or contain mostly text. Files with many photos or scans shrink the most.
Compress it, check the size, and if it is still too big compress again at a stronger level or split the PDF into parts.
