Compress PDF
Reduce your PDF size without wrecking the quality. Pick a compression level, see how much you save, then download. This PDF compressor runs in your browser, so your file is never uploaded.
Three compression levels, your call
Pick from three levels: "Recommended" for the best balance, "Strong" for a smaller file with a slight quality drop, and "Maximum" for the smallest file to share. Match the level to the job.
See the savings before you download
After it runs, the tool shows the new size next to the original, so you know exactly how much you saved and can switch levels before you keep the file.
Shrinks the parts that make PDFs heavy
Most of a big PDF's size comes from photos and scanned pages. This tool squeezes those down for a real size drop, not the kind of trick that trims a few hidden extras and barely changes the file.
Your text and pages stay intact
Compression recompresses the images, so your text stays sharp and selectable and the page count does not change. You get the same document, only lighter.
Your PDF never leaves your device
The file is compressed inside your browser and is never uploaded, stored, or scanned. There is no size cap, so large scans open at once, and a contract, ID, or medical record stays with you.
Free, with no watermark on the result
No account, no email, and no payment. Your downloaded PDF carries no watermark. It is your document, only smaller, with nothing stamped on the pages.
How to compress a PDF
Add your PDF
Drag your PDF into the box above or pick it from your device. It opens straight in your browser. Nothing is uploaded to a server.
Choose a compression level
Select "Recommended", "Strong", or "Maximum". Each level shows the trade-off between a smaller file and image quality, so you can match it to the job.
Compress and compare
Start the compression and see the new size next to the original. If it is not small enough, switch to a stronger level and try again.
Download your smaller PDF
Save the compressed file to your device. It keeps the same pages and text, with no watermark added to your document.
PDF compressor questions
When to reduce your PDF file size
Send it by email
Email providers cap attachments, often around 25 MB, and a photo-heavy report or scanned contract can sail past that. Compress the PDF first and it slips under the limit, so you can attach and send it without splitting it up or setting up a file-sharing link.
Get past an upload form
Job portals, visa applications, and government forms often reject a PDF that runs over a few megabytes. Drop your file in, pick a level that brings it under the cap, and download a version the form will accept, without redoing the scan.
Save space and share faster
Scanned documents eat storage on your phone, laptop, and cloud drive. Compressing them frees space and makes every upload and download quicker. It is a fast way to tidy a folder of bulky PDFs before you archive or share them.
