Frequently Asked Questions
How do I compress a PDF for free?
Upload your PDF to pdfGens, click Compress PDF, and download the result. Everything runs in your browser — no file is uploaded to any server. It's completely free with no watermarks.
Does compressing a PDF reduce quality?
pdfGens compresses PDFs by stripping redundant data and optimizing the file structure. For most text-based documents, there is no visible quality loss.
Is there a file size limit?
Since processing happens entirely in your browser using local memory, there is no imposed limit. PDFs up to 100MB typically work well depending on your device.
Are my files safe?
Absolutely. Your files never leave your device. pdfGens processes everything using browser-based JavaScript — no data is sent to any server at any point.
