About Sleek PDF

Sleek PDF is a free set of PDF tools built on a simple idea: modern browsers are powerful enough to do everyday PDF work — merging, compressing, flattening, organizing — without sending your files to anyone's server.

Because your device does the work, we don't pay for processing servers, and we don't need to limit you to recover costs. No daily caps, no watermarks, no file-size paywalls, no accounts. The site is supported by unobtrusive ads — never inside the tools themselves.
