Frequently asked questions
Will compressing make the text blurry?
No. Text, vector graphics, links and bookmarks are kept exactly as they are. Only photos and scanned images are re-encoded and resized, so the result stays sharp when you zoom in on text.
Which level should I choose?
Recommended suits most documents. Use Light when image quality matters most, and Strong when you need the smallest possible file, for example to meet an upload limit.
Why did my PDF hardly get smaller?
PDFs that are mostly text, or that were already optimized, have little left to remove. The biggest savings come from documents with photos or scanned pages.
Are my files uploaded?
No. Compression runs entirely in your browser, so your documents stay on your device.
