Frequently asked questions
Why does compressing turn text into an image?
This tool works by re-rendering each page as a compressed JPEG, which is how browser-only compression achieves real size savings without a server. It's most effective on scans and photo-heavy PDFs.
Will this work well on a text-only document like a report?
You'll see a size change, but you'll lose the ability to select or search the text. For text-heavy PDFs, only compress if file size matters more than text selectability.
How much smaller will my file get?
It depends heavily on the source PDF and quality setting — the tool shows you the before/after size so you can judge the trade-off before downloading.
