How it works

How to compress a PDF to reduce file size

  1. 1

    Upload your PDF

    Drop the PDF onto the uploader. The original file size is displayed so you can gauge how much reduction to expect.

  2. 2

    Choose a compression preset

    Select Web for maximum size reduction, Reading for a balanced result, or Print for high-quality output with moderate compression.

  3. 3

    Download the compressed PDF

    Click Compress. The tool re-renders pages as optimized JPEGs and rebuilds the PDF locally, then downloads the result to your device.

Large PDFs slow down email attachments, fill up storage, and frustrate recipients on mobile connections. The PDF compressor in PDFsuite reduces file size by re-rendering each page as an optimized JPEG at the quality level you choose. The three presets - Web, Reading, and Print - give you a straightforward way to balance file size against visual quality depending on how the document will be used.

Compression runs completely offline in your browser. Sensitive documents like tax returns, medical records, or client contracts are processed locally and never uploaded to any server. There is no account required and no limit on how many times you can compress a file. The tool works page by page, so even a 500-page document is handled without crashing the browser tab.

For most office documents and scanned forms, the Reading preset cuts file size by 50-70 percent while keeping text crisp enough for comfortable reading on screen or in print. The Web preset pushes compression further - useful when you need to attach a PDF to an email with a strict size limit. The Print preset is best for design work or documents where image fidelity matters.

FAQ

Common questions

How much will compression reduce my PDF size?
Results vary by content. Scanned image-heavy PDFs compress most - often 60-80 percent. PDFs with mostly vector text compress less, typically 20-40 percent depending on the preset chosen.
Is PDF compression free and private?
Yes to both. Compression is free with no file-size caps. Your PDF is processed entirely in your browser - no upload, no server, no data stored anywhere.
Which preset should I choose?
Web is best for email or web sharing where small size matters most. Reading is the all-purpose default. Print is for high-quality output when the document will be printed or displayed at large size.
