Frequently Asked Questions about PDF Compression
How does PDF compression work?
Our tool renders each PDF page as an image and re-encodes it as JPEG at the selected quality. The result is a lighter PDF that visually preserves text and graphics.
How much can a PDF file size be reduced?
It depends on the content. PDFs with many high-resolution images can be reduced by 70-90%. Text-heavy documents will see more modest reductions.
Can I select text in the compressed PDF?
Since pages are rendered as images, text in the resulting PDF will not be selectable. If you need selectable text, use the highest quality setting.
Is there a file size or page limit?
There is no limit imposed by us. The real limit is your browser memory and processing capacity. Very large PDFs (>100 MB or >500 pages) may take longer.
Are my PDFs private?
Absolutely. Your files are never sent to any server. All processing happens locally on your device, so your documents are completely private.
