Compress PDF for ATO Uploads: Keep Files Under 2 MB, Readable for Audit

Reduce scanned PDFs to under 50 MB or smaller for ATO uploads. No signup, no watermark, files deleted after one hour.

    Runs the same engine as our Compress PDF tool.

    ATO document uploads accept PDF and cap file size at 50 MB. If your scan exceeds that, compress it here. GekiPDF rewrites the file using Ghostscript presets — Light (~200 DPI), Recommended (~150 DPI), or Extreme (~96-120 DPI). The text layer stays intact, so records remain searchable and readable for audit.

    A 16-page scan typically processes in about 1 second. Metadata is stripped, which can help with privacy. Files are deleted after one hour, and you get up to 40 conversions per hour per IP. No signup, no watermark.

    Frequently asked questions

    Will compression make my ATO documents unreadable?

    No. Use the Recommended preset (150 DPI) for most scans; text remains legible. Only use Extreme if file size is still too large. Test a page first.

    How small will my PDF get?

    Depends on original content. A 300 DPI colour page drops from ~1.2 MB to ~150 KB at 150 DPI greyscale. Total reduction can be up to 95%.

    Is there a limit on file size or number of files?

    Yes. Each file must be under 50 MB. You can do up to 40 conversions per hour per IP address.
