Why Use Luleit's PDF Compressor?

Frequently Asked Questions

How much can I reduce my PDF file size?+

Results vary depending on the PDF content. Documents with embedded fonts and unused objects typically see 20%–60% reduction. Image-heavy PDFs may see less reduction since images are preserved at original quality.

Does compression reduce quality?+

No. Luleit's compression removes unnecessary data like duplicate fonts, unused objects, and metadata — the visual content of your PDF remains identical.

Is my PDF uploaded to a server?+

No. All compression happens locally in your browser using JavaScript. Your file is never sent anywhere.
