Compress PDFs Under 200KB Without Blurry Text
Most web compressors render your documents into blurry low-resolution images. Our premium engine dynamically balances custom high-DPI scaling and vector optimization to ensure 100% original print fidelity.

How OptiPDF Prevents Blur
1. Local Multi-Pass Solver
Instead of arbitrarily lowering quality, our app runs a lightweight preview pass. It computes the absolute highest possible rendering density (DPI) and quality factor that fits exactly inside your chosen target file size.
2. Vector Font Alignment
For pure vector documents, choose Lossless mode. It strips redundant page layouts, stream parameters, and invisible metadata tags without touching the core shapes or embedded typography.
3. High-DPI Re-scaling
Scanned documents are rendered up to 300 DPI, processed with pixel-preserving sharpening, and output in full dimension to ensure printing or zooming reveals clean lines, instead of gray pixel blocks.
Frequently Asked Questions
Is my data secure?
Yes, entirely. Your document never leaves your machine. All calculations, vector processing, rendering, and rebuilding of the compressed file take place in memory directly inside your browser tab using native JavaScript.
What is the difference between “High-Fidelity” and “Lossless” modes?
High-Fidelity (scanned mode) works incredibly well on images, paperwork, receipts, and hand-marked PDFs, re-rendering them using high-DPI scaling. Lossless focuses on pure vector PDFs (like invoices generated by systems, word-processor exports) by rebuilding internal metadata structures to shrink file sizes perfectly without altering text sharpness.
Can I guarantee it lands under 200KB?
Yes. By enabling the Target File Size Limit Auto-Solver and moving it to 200KB, the engine will run compression trials to find the correct DPI and compression variables. Keep in mind that extremely long documents (e.g., 50+ pages) may require lower DPI settings to fit under 200KB.
