How much smaller will my PDF get?
It depends on the file. Text-heavy PDFs with redundant objects compress well; image-heavy PDFs see smaller gains.
Is the compression lossless?
Yes. We re-pack the PDF without re-encoding images, so visual quality is unchanged.
Is the first use really free?
Yes. Every visitor gets one free document per tool. Signed-in accounts also get one free document, then each use costs credits.
