Reduce file size while optimizing for quality in your browser. Secure, no signup, no watermark.
PDF compression works by optimizing images, removing duplicate object streams, and subsetting embedded fonts. Choosing the right preset depends on your use case:
| Preset | Image Resolution | Expected Size Reduction | Best For |
|---|---|---|---|
| Low (Max Compression) | 72 DPI | Up to 80% | Quick web uploads, low-bandwidth viewing |
| Medium (Standard) | 150 DPI | Up to 50% | Everyday sharing, job applications, resumes |
| High (Print Quality) | 300 DPI | Up to 25% | Printing, official legal documents |
No, vector text, shapes, and layouts are preserved in high quality. Only bitmap images inside the PDF are resampled and compressed.
