About Our Compression Method
- Structure Optimization: This tool provides a basic level of compression by optimizing the PDF's internal structure and removing redundant data.
- Image Handling: It currently focuses on structure rather than heavy image re-compression, which preserves visual quality but may offer milder size reductions for scanned documents.
Your Privacy is Our Priority
This tool runs entirely in your browser. We do not upload, store, or analyze your files. Everything you process stays on your device. Period.
FAQ
How do you compress the PDF without uploading it?
Our tool runs directly in your browser. It rewrites and optimizes the PDF's internal structure locally on your computer. Your file is never sent to a server.
How much will my file size be reduced?
The reduction amount varies greatly depending on the original PDF. Documents with redundant data or inefficient structures will see significant savings. However, already optimized PDFs may see little change.
Will compressing the PDF reduce its quality?
Our basic compression method primarily removes unused objects and optimizes the document structure. It does not re-compress images or alter visible content, so the quality should remain largely unchanged.
