PDF Under 100KB for Passport

Use RatPDF's free PDF compressor — Ghostscript-powered, no signup required.

Submission portals reject more applications for file size than for content errors. This page covers pdf under 100kb passport with a checklist you can follow in under five minutes.

Portal requirements

Upload fields often show "Max 100kb" without explaining whether that is KB or MB. Right-click your PDF → Properties (Windows) or Get Info (Mac) to read exact byte size before uploading.

Preparation checklist

Scan at 150 DPI greyscale unless colour is mandatory.
Crop empty margins in Preview or any image editor.
Compress with RatPDF PDF Compressor — start Recommended, then Extreme.
Verify text remains readable at 100% zoom.
Rename file per portal instructions (no spaces if forbidden).

If rejection persists

Split multi-page PDFs and upload only required pages. Some passport flows want one JPEG per photo — export with PDF to Images if PDF is not accepted at all.
