Why switch from LightPDF to FreeConversion?

LightPDF (https://lightpdf.com) is a popular tool, but it has significant limitations. The main difference with FreeConversion is privacy: unlike LightPDF which sends your files to remote servers, FreeConversion processes everything locally in your browser using WebAssembly technology.

This means your sensitive documents (contracts, resumes, bank statements) never leave your computer. Additionally, FreeConversion is 100% free with no file limits, no registration, and no ads.

Frequently Asked Questions

Is this PDF compressor free?

Yes, our PDF compressor is completely free. No hidden fees, no registration required, and no file size limits.

Can I compress multiple PDFs at once?

Currently, you can compress one file at a time. However, the process is very fast and you can compress as many files as you want consecutively.

What's the difference between compression levels?

Low compression (10-30% reduction) preserves maximum quality. Medium (30-50%) offers a good balance. High (50-70%) significantly reduces size with slight image quality loss. Maximum (70-90%) creates the smallest possible file.

Can I use FreeConversion for professional documents?

Absolutely! FreeConversion is perfect for professional documents. Since all processing happens locally in your browser, your confidential documents remain 100% private.
