How to Compress a PDF to Under 100 KB — Free

Some government portals, job applications, and insurance forms require PDFs under 100 KB. Achieving this requires both maximum compression and smart preparation.

1

Step 1 — Remove Unnecessary Pages First

Before compressing, go to pdfeditor.onl/organize-pdf and extract only the pages you need. Removing pages reduces size more than compression alone for multi-page documents.

2

Step 2 — Apply Strong Compression

Go to pdfeditor.onl/compress-pdf. Upload the trimmed PDF. Select Strong compression. Click Compress Now.

Tip: For a single-page text-only PDF like a resume, Strong compression typically brings the file under 50 KB.

Step 3 — Convert via JPG If Still Too Large

If the PDF still exceeds 100 KB after Strong compression, convert it to JPG at pdfeditor.onl/convert-pdf, then convert the JPG back to PDF. This forces re-encoding at much lower resolution.
