GekiPDF

Compress PDF under 25 MB for Gmail, Outlook, and corporate email

Free online PDF compressor – no signup. Reduce any PDF to under 10 or 20 MB in seconds. Files deleted after one hour.

    Runs the same engine as our Compress PDF tool.

    Gmail rejects attachments over 25 MB, Outlook often caps at 20 MB, and many corporate mail servers stop at 10 MB. Upload your PDF to GekiPDF's compress tool, pick a preset (Light, Recommended, or Extreme), and download a smaller file that fits the limit. No signup, no watermark, files up to 50 MB per upload.

    The tool uses Ghostscript to rewrite your PDF and drop metadata while keeping the text layer selectable. A 16-page scan takes about 1 second to compress. Choose Light (~200 DPI) for near-original quality, Recommended (~150 DPI) for most email needs, or Extreme (~96-120 DPI) when you need the smallest size possible.

    Frequently asked questions

    What is the maximum file size I can upload?

    You can upload files up to 50 MB each. The compressed output will be smaller than your original, but if your source is already under 30 MB, you'll likely get it under 25 MB.

    Will my text still be searchable after compression?

    Yes, the text layer is preserved. Compression only downsamples images and removes metadata; it does not rasterize text.

    How long are my files stored on your server?

    Uploaded and processed files are deleted automatically after one hour. You don't need an account, and nothing is kept longer.
