Compress PDF for ELSTER and German Authority Portals

Reduce PDF size to under 10 MB for ELSTER and German authority uploads. Free, no signup, no watermark. Files deleted after one hour.

    Runs the same engine as our Compress PDF tool.

    ELSTER and many German authority portals accept PDF attachments only up to a certain size limit, often 10 MB, and reject files with encryption or passwords. If your scanned document is too large, you need to compress it before uploading. GekiPDF's compress-pdf tool rewrites your PDF using Ghostscript presets (Light ~200 DPI, Recommended ~150 DPI, Extreme ~96-120 DPI), which drops metadata but keeps the text layer so it stays searchable.

    Upload a file up to 50 MB and choose a preset based on your needs. For a typical 16-page scan, the process takes about 1 second and can reduce file size by up to 95%, depending on the original resolution. The output has no watermark and requires no signup. Your file is processed in memory and deleted from our servers after one hour, so you can attach it to your ELSTER submission without worrying about privacy.

    Frequently asked questions

    What is the maximum file size I can upload?

    You can upload files up to 50 MB per file. After processing, the compressed file will be smaller, often well below the 10 MB limit that ELSTER typically accepts.

    Will compression remove the text layer?

    No. GekiPDF's compression keeps the text layer intact, so your PDF remains searchable and selectable. It only removes metadata like author or creation date.

    Does GekiPDF add a watermark or require an account?

    No watermark and no signup needed. The service is free, and you can make up to 40 conversions per hour per IP address.
