Quick Tips
- 📄 For 100KB target with 10+ pages, use Low quality - that's only ~10KB per page!
- 📊 Use % Reduction mode when you don't need exact size - easier for large PDFs.
- ⚡ Processing time depends on page count. 20+ pages may take 30-60 seconds.
How to Use PDF Optimizer
📤 Step 1: Upload PDFs
Drag & drop or click to select PDF files up to 50MB each. Multiple files supported for batch compression.
🎛️ Step 2: Choose Mode
Target KB: Set exact file size (100KB, 200KB, etc). Best for
strict upload limits.
% Reduction: Reduce by percentage (50%, 70%, 90%). Easier when you just
need "smaller".
⚙️ Step 3: Select Quality
High: Best visual quality, larger files. Medium: Balanced (recommended). Low: Maximum compression, some quality loss.
🎯 Understanding Limits
A 10-page PDF targeting 100KB = 10KB per page. That's very aggressive! If you can't reach target, the tool will get as close as possible and show a suggestion.
✨ Step 4: Compress & Download
Click "Compress All" and wait for processing. Progress shows current page and time estimate. Download individually or use ZIP for batch.
🔒 Privacy & Security
100% browser-based. Your PDFs never leave your device - safe for contracts, IDs, bank statements, and confidential documents.
