Why File Size Matters

Many online portals, government websites, email providers, and application systems enforce strict file size limits. When a file is too large, uploads fail silently or get rejected with unhelpful error messages.

If you need to compress pdf to 100kb without losing quality, your target is typically used for: **government portals, application forms, ID uploads**. Significant compression — fine for documents, may reduce image sharpness.

Size vs Quality: Understanding the Trade-Off

File compression works by removing redundant data. For PDFs, this means down-sampling embedded images, removing metadata, and flattening transparent layers. For images, it reduces pixel information per area.

GenZDoc offers multiple compression levels. For text-heavy documents, even High compression retains perfect readability. For image-heavy files, choose Medium or Low compression to preserve visual fidelity.
