About This Tool

Government portals like DigiLocker, NSDL, and income tax portals have strict file size limits, often 1–2 MB. Scanned PDFs frequently exceed these limits.

Our PDF Compressor renders each page at reduced quality using your browser's canvas engine — no server upload needed, completely private.

  • Works entirely in your browser — zero server upload
  • Adjustable quality and scale settings
  • Supports multi-page PDFs
  • Shows exact before/after file size comparison
  • Free, no watermark added

Frequently Asked Questions

How much can this tool reduce my PDF size?
Results vary depending on the content. Image-heavy PDFs typically achieve 40–80% reduction. Text-only or already-compressed PDFs may see less reduction. Using "Low" or "Minimum" quality gives the smallest output.
Will the text still be readable after compression?
Yes, at "Medium" or "High" quality settings, text remains very readable. At "Minimum" quality, there may be slight blurring — suitable for submission purposes but not for printing. We recommend Medium for the best balance of size and quality.
Is my PDF uploaded to any server?
No. This tool uses PDF.js and jsPDF — both JavaScript libraries that run entirely in your browser. Your PDF file never leaves your device. It is completely private and secure.
What is the maximum file size supported?
The tool supports files up to 50 MB. Very large files (30–50 MB) with many pages may take a minute or two to process. Processing speed depends on your device's CPU and RAM.
