Compress a 30 MB PDF from PowerPoint to under 5 MB

Reduce a 40-slide deck exported to PDF from 30 MB to under 5 MB. Free, no signup, no watermark. Up to 50 MB per file.

    Runs the same engine as our Compress PDF tool.

    A 40-slide deck exported to PDF is often 30 MB because every slide keeps its images at full resolution. That size blocks email attachments and slows uploads. GekiPDF's compress-pdf tool rewrites the file using Ghostscript presets, dropping image DPI while keeping the text layer intact.

    Choose Light (~200 DPI) for near-original quality, Recommended (~150 DPI) for most uses, or Extreme (~96-120 DPI) for the smallest file. A 16-page scan takes about 1 second; your deck will take longer but still finish in seconds. Files up to 50 MB are accepted, and everything is deleted after one hour.

    Frequently asked questions

    Will the text become blurry after compression?

    No. The text layer is kept as vector data, so it stays sharp. Only the embedded images are downsampled to the chosen DPI, which reduces file size without affecting readability.

    What's the difference between the three presets?

    Light (~200 DPI) gives the best image quality but less reduction. Recommended (~150 DPI) balances size and clarity. Extreme (~96-120 DPI) creates the smallest file, but images may look pixelated when zoomed in.

    Can I compress multiple files in a row?

    Yes, you can run up to 40 conversions per hour per IP address. Each file must be under 50 MB. There's no queue; just upload and download each result directly.
