Frequently Asked Questions

How does this PDF compressor work?
It reads the PDF, extracts embedded images, re-renders them at a reduced quality, and repackages the result. This is a client-side approach ideal for image-heavy PDFs.
Will I lose text quality?
No. Text elements remain intact. Only embedded images are recompressed, so your text stays crisp and clear.
Is it safe to use?
Absolutely. Your file is processed entirely in your browser. Nothing is ever uploaded to our servers.
What's the maximum file size?
You can compress PDFs up to 100MB. Larger files may take a bit longer but will still work in most browsers.
Does it add a watermark?
No, never. LovelyDoc is 100% free with no watermark on any tool.
