Frequently Asked Questions
How much smaller will my PDF get?
It depends on the content. Scanned documents and image-heavy PDFs often shrink 50–90%; text-only PDFs are already compact and may barely change. If compression cannot make your file smaller, you get the original back unchanged.
Which level should I choose?
Balanced is right for almost everything — documents stay crisp on screen at a fraction of the size. Use Maximum when file size matters more than image quality (email limits), and Light when the PDF will be printed.
Will compression change my text?
No. Text stays vector-perfect and selectable. Compression works by downsampling embedded images and optimizing the file's internal structure.
Is my document kept on the server?
The file exists in temporary server storage only for the seconds the compression runs, then it is deleted automatically. Nothing is retained or shared.
