Compress PDF
Reduce PDF file size without losing quality — entirely in your browser. Nothing is uploaded to any server.
How PDF Compression Works
PDF compression reduces file size by optimizing internal structures like fonts, images, and metadata. Our tool processes everything in your browser — your files never leave your device.
The algorithm removes duplicate font subsets, downsizes embedded images to web-optimized quality, strips unnecessary metadata, and recombines stream objects to eliminate redundancy.
Unlike server-based compressors, browser-based compression means zero upload time, no file size queues, and complete privacy. Very large files (100 MB+) may run slower on low-powered devices.
Why Compress PDFs?
Email providers typically limit attachments to 20–25 MB. Compressed PDFs fit within these limits without splitting documents. Freelancers sending invoices and contracts benefit from smaller files that download instantly for clients.
Smaller PDFs also load faster on mobile devices and consume less storage. Archiving years of business documents with compression can reduce your total storage footprint by 40–70%.
