Is the PDF Compressor free to use?

Yes, our PDF Compressor is completely free with no hidden charges, subscription fees, or registration requirements. You can compress as many PDFs as you need without any limitations.

What compression modes are available?

We offer two compression modes: 1) Lossless Recompress - preserves original quality with moderate size reduction, and 2) Smart Rasterize - converts pages to optimized images for maximum file size reduction. Both modes process files securely in your browser.

Is there a file size limit?

Our tool can handle PDF files up to 100MB. There are no page count restrictions. For very large documents, we recommend using the Smart Rasterize mode for optimal compression results.

Are my PDF files secure during compression?

Absolutely! All compression happens directly in your browser. We never upload, store, or access your PDF files on our servers. Your documents remain 100% private and secure on your device.

How much compression can I expect?

Compression results vary based on file content: Text-heavy PDFs can reduce by 50-70% with lossless mode, while image-heavy documents can reduce by 80-90% with rasterization. The tool shows real-time size comparisons.

What is Smart Rasterize mode?

Smart Rasterize converts PDF pages to optimized JPEG images and embeds them back into a PDF. This mode offers the highest compression rates, especially for scanned documents and image-heavy PDFs, with adjustable quality settings.

Does compression affect PDF quality?

Lossless Recompress mode maintains original quality. Smart Rasterize mode offers adjustable quality settings (40-100%). We recommend testing different quality levels to find the optimal balance between file size and visual quality.

Can I compress multiple PDFs at once?

Currently, our tool processes one PDF file at a time. This ensures optimal compression results for each document. You can compress multiple files sequentially, and your compression history is saved for reference.
