Compress PDF Without Losing Quality — Free & Private
If you need to share a PDF that will be printed, presented, or scrutinized closely, quality matters. Our Best Quality compression mode reduces file size by 20–40% while keeping text sharp and images visually indistinguishable from the original at normal viewing sizes. Your PDF is never uploaded — it is compressed entirely in your browser.
Recommended setting: Best Quality — Use Best Quality if you are compressing a portfolio, presentation, or document that will be viewed at 100% zoom or printed. Use Balanced for documents shared over WhatsApp or email where screen quality is sufficient.

Frequently Asked Questions
Can you compress a PDF without any quality loss?
Lossless PDF compression (which removes metadata and redundant data without touching images) typically yields only 5–10% reduction. Our Best Quality mode uses very light JPEG compression that is visually lossless for most practical purposes, achieving 20–40% reduction.
Which compression level preserves the most quality?
Best Quality is the recommended setting if quality is your priority. It applies the lightest compression and the highest image fidelity. Balanced is next — it is imperceptible on screen. Maximum Compression applies the strongest compression and is best for file size targets, not quality preservation.
Will the compressed PDF print correctly?
With Best Quality mode, yes. The output PDF prints at a quality that is visually equivalent to the original for most documents. If you are printing large format or at very high DPI, use the original file.
