Why 100KB? Where It's Required
Many Indian government portals — UPSC, SSC, Railway recruitment, banking exams, and university admissions — require uploaded documents under 100KB. Email attachments also benefit from smaller PDFs that load instantly.
Step 1: Upload Your PDF
Go to our free PDF compressor and drag-drop your PDF file. We support files up to 50MB.
Step 2: Select Maximum Compression
Choose the "Maximum Compression" level. This applies aggressive optimization:
- Removes hidden metadata (author info, creation date, software tags)
- Downsamples images to web-friendly resolution
- Optimizes font subsets (only keeps characters used in the document)
Step 3: Enable All Optimization Options
Toggle on:
- Remove Metadata — strips 5-20KB of hidden data
- Optimize Fonts — reduces embedded font size by 30-50%
- Compress Images — the biggest size reducer for scanned documents
Step 4: Download Your Compressed PDF
Click download and verify the size. Most text-based PDFs compress to well under 100KB. Scanned documents may need additional image quality reduction.
What If It's Still Over 100KB?
For image-heavy PDFs:
- Convert to grayscale before compressing (reduces file size by 40%)
- Reduce the scan DPI from 300 to 150
- Split multi-page documents into individual pages using our PDF Splitter
Tips for Specific Use Cases
Government Form Uploads (UPSC, SSC, IBPS)
These portals often accept only PDF format under 100KB. Scan your document at 150 DPI, save as PDF, then compress with our tool.
Email Attachments
While email allows larger files, 100KB PDFs load instantly on mobile. Your recipients will thank you.
WhatsApp Document Sharing
WhatsApp compresses images but not PDFs. A 100KB PDF shares and opens faster than a 5MB one.
