Frequently Asked Questions
Does anything get uploaded?
No. All processing happens in your browser using JavaScript. Files are never sent to our servers.
Which compression level should I use?
Use Low for documents you'll print or need maximum quality. Medium is good for most purposes. High is best when file size is critical and some quality loss is acceptable.
Why didn't my file get much smaller?
PDFs that are already optimized or contain mostly text won't compress much further. Image-heavy PDFs typically show the best compression results.
