Why compress PDF files?

Large PDF files are difficult to share via email, slow to upload, and take up storage space. Compressing a PDF reduces its size while maintaining readability, making it easier to share and store.

How does it work?

Our compressor finds images embedded in your PDF and recompresses them at a lower quality level. You can choose between low, medium, and high compression. The text and layout of your PDF remain unchanged.

Compression levels

Low compression (80% quality) slightly reduces file size while maintaining near-original image quality. Medium compression (60%) offers a good balance. High compression (40%) maximizes size reduction but images may show more artifacts.

FAQ

Is the compression secure?

Absolutely. Your PDF is compressed directly in your browser and is never sent to any server.

Will text quality be affected?

No, only embedded images are recompressed. Text, fonts, and layout remain unchanged.

Why is my PDF not getting smaller?

PDFs without images (text-only documents) will see minimal size reduction. The compression primarily targets embedded images.

What is the maximum file size?

You can compress PDFs up to 25 MB for free. With the Pro plan, the limit goes up to 100 MB.
