Make PDF Files Smaller Without Losing Clarity

Large PDFs get rejected by email servers, upload forms and application portals. This compressor reduces the file size of scanned documents, presentations and forms while preserving the layout, fonts and embedded images, so the document still looks exactly as it should. You control the compression level, and the tool shows the file size before and after so you can see exactly how much you saved.

How to use it

  1. Click Upload and select your PDF.
  2. Choose a compression level that balances size and quality.
  3. Compress and download the optimized file.

The whole process runs in your browser — there is no server and no upload, which keeps confidential documents private and makes compression almost instant. It is built for professionals, educators and anyone who manages large PDF documents, and it is free with no watermark and no sign-up.

Frequently Asked Questions

Will compressing my PDF reduce its quality?

You choose the compression level. The tool is designed to shrink the file while keeping text and images clear and the original formatting intact.

Is my PDF uploaded anywhere?

No. Compression happens entirely in your browser; your document never leaves your device.

How much smaller will my file get?

It depends on the file — image-heavy PDFs shrink the most. The tool shows the before and after sizes so you can check the saving before downloading.

Does it add a watermark?

No watermark, no sign-up and no cost.
