Reduce PDF file size below 100KB when portals block submission entirely over the cap. This page uses the same target-size compressor with guidance for scans, photos, and multi-page documents that need aggressive shrinking.

If still over 100KB, remove cover pages, crop scanner margins, or convert color scans to grayscale before compressing again.

How to use this tool

Upload, pick 100KB target, download, confirm size in OS file properties, repeat with fewer pages if needed.

Worked example

Example: portal error 'file must be under 100KB'—compress, verify size, resubmit same day.

When to use this

  • Portal hard-rejects over-limit files.
  • Consulate or licensing uploads.
  • Legacy systems with very small caps.

Common examples

  • 2.1 MB job-application PDF → 200 KB preset for a 250 KB portal cap.
  • Scanned syllabus at 4 MB → 500 KB preset before LMS upload.
  • One-page invoice PDF → 100 KB preset for legacy email gateways.
  • Portfolio PDF with photos → 500 KB then manual review of text sharpness.
  • Government form scan → 200 KB with readable 10 pt body text.

How it works

Upload a PDF, pick a target size (100 KB, 200 KB, or 500 KB), and compress via the same secure server pipeline as our standard PDF compressor. The result shows actual file size versus your target and notes when the target cannot be reached.

Limitations

Compressed files are stored temporarily and deleted automatically. Results depend on PDF content; scanned pages may not reach aggressive targets.

FAQ

Frequently asked questions

Same as compress PDF to 100KB?

Yes—same tool with intent-focused guidance for sub-100KB requirements.

Merge then compress?

Merge related PDFs first if allowed; otherwise compress each part separately.

Quality too low?

Try 200KB preset if portal allows—100KB is aggressive for photo scans.
