Frequently asked questions

PDF compression questions

How do I compress a PDF file?

Select the document, choose lossless optimization or visual compression and select Compress PDF.

What is the difference between lossless and visual compression?

Lossless optimization preserves text, links, vectors and forms. Visual compression turns each page into an image and usually provides greater reduction.

Will the text remain selectable?

Yes with lossless optimization. Visual compression turns pages into images, so text will no longer be selectable.

Why do some files not become smaller?

Some PDF files are already optimized or contain structures that cannot be reduced further without rasterizing the pages.

Is my document uploaded to a server?

No. The file is processed locally inside your browser.
