How does exact KB compression work on PDF documents?

ToolKB analyzes the internal streams of your PDF. It first removes redundant metadata and duplicate fonts. If the file is still above the target limit, it adaptively scales high-resolution scanned page images until the file fits within your specified KB threshold.

Will text remain selectable after compression?

For standard documents that achieve target size via stream optimization, vector text remains intact. For scanned documents or heavy image PDFs compressed to very small thresholds like 100KB, pages are re-encoded as high-contrast images to ensure they pass portal upload limits.

Can I use this for SSC, UPSC, and state PSC portal uploads?

Yes. Many Indian government portals require certificates, disability documents, or category proofs to be uploaded strictly under 100KB or 200KB. ToolKB is calibrated specifically for these limits.

info

Exact-KB Scanned Document Optimization:When compressing to strict government exam limits (e.g. 100KB or 200KB), document pages with large raster scans are re-encoded. Text inside rasterized scans becomes part of the page image. Always inspect your download before portal submission.
