How to Compress PDF to 100kb/200kb Without Losing Quality

Published on July 7, 2026 | Written by PDFHj Team

Many online job application portals, university admission systems, and government websites have strict file size limits. They often require you to upload PDF documents that are no larger than 100kb or 200kb. Attempting to compress these files manually often results in blurry text or unreadable images. Here is how you can achieve perfect compression quickly and securely.

Why Do PDFs Get Too Large?

PDF documents can grow significantly in size if they contain high-resolution scanned pages, embedded fonts, or complex color graphs. To make them smaller, compression algorithms need to optimize images and discard redundant metadata without affecting the visual quality of your text.
