You don't have to choose between a smaller file and a readable one. Light mode rewrites the PDF's internal structure — removing redundancy and unused data — without re-encoding the pages, so text stays vector-sharp and fully selectable.
It's the right setting when you need a smaller PDF for email or upload but can't afford blurry pages. Everything is processed locally in your browser.

Questions, answered
Q.Will the text still be selectable and searchable?
Yes. Light mode never rasterizes pages, so text remains real text — selectable, searchable and crisp at any zoom.
Q.Are my files uploaded to a server?
No. Every operation runs entirely in your browser using JavaScript, so your files never leave your device. Open your browser's Network tab and watch — nothing is sent or stored.
Q.Is it free? Do I need an account or to install anything?
It's completely free with no sign-up, no email and nothing to install. There are no daily limits and no watermarks on your output.
Q.Does it work on Mac, Windows, Chromebook and phones?
Yes. It runs in any modern browser — Chrome, Edge, Firefox or Safari — on Windows, macOS, Linux, Chromebook, iPhone and Android. There is nothing to download.
