Compress PDF

Reduce PDF file size — fast, free, no watermark.

A free online tool to compress PDF files and shrink their size while keeping the document readable. Reduce reports, scanned docs, ebooks, and image-heavy PDFs to fit email and upload limits. No signup, no watermark.

  1. Upload your PDF — Drag and drop your PDF onto the page or click to browse and select it. Zebra handles scanned documents, reports, ebooks, and image-heavy files.
  2. Pick a quality preset — Choose low, medium, or high compression. Higher compression makes the smallest file, while a higher quality preset preserves more detail for sharp text and images.
  3. Compress the file — Zebra reduces the file size while preserving readability so your document stays clear and easy to read.
  4. Download the smaller PDF — Save the compressed PDF to your device. It is ready to attach to email, upload to a portal, or store with less space.

Is the Zebra PDF compressor free?

Yes. Compressing PDFs on Zebra is completely free with no signup required and no watermark added to your file.

Will compressing reduce the quality of my PDF?

Zebra reduces file size while preserving readability. Pick a higher quality preset to keep more detail, or a lower one for the smallest possible file.

Can I compress a PDF to fit an email attachment limit?

Yes. Compression is great for fitting common limits like Gmail's 25MB and Outlook's 20MB caps, as well as portal upload limits. Try the medium or low preset if you need a smaller result.

What kinds of PDFs can I compress?

Zebra works with scanned documents, reports, ebooks, and image-heavy PDFs. Image-heavy and scanned files usually see the biggest size reduction.

Do I need to install anything or create an account?

No. The compressor works right on the page — nothing to install, no account to create. Just drop your PDF and download the smaller file.

How do I choose the right compression preset?

Use high quality when you need crisp text and images, medium for a balance of size and clarity, and low when you need the smallest file to meet a strict size limit.
