Is it free to shrink a PDF's file size on Chromebook?

Yes. Every core FernPDF tool is free, with no account, no watermark, and no trial limits.

Where does the smaller file end up on Chromebook?

It downloads straight to the Files app, under Downloads, ChromeOS's single file manager for anything a browser saves, the normal place Chrome on ChromeOS saves anything, not a special location just for FernPDF.

Will it add a watermark?

No. None of the three levels stamps anything onto the page.

How to shrink a PDF's file size on Chromebook

You don't need special software to shrink a PDF's file size on Chromebook. FernPDF runs entirely in Chrome on ChromeOS: open the tool, drop your file, download the result. Compression re-encodes the document on your device. Image-heavy and scanned PDFs shrink the most, often 60–90%.

On Chromebook, you drag it into the drop zone, or click to open the Files app picker. Once the smaller file is ready, it downloads to the Files app, under Downloads, ChromeOS's single file manager for anything a browser saves.

There's no separate installed-apps layer to manage: a Chromebook's Files app is also where an Android app's saved files and a Linux container's files would show up, so Downloads is the one place to check.

Chromebooks are built around the browser, which makes them a perfect match for browser-native PDF tools, no Android app or Linux container needed.

FAQ

Common questions

Yes, FernPDF is a web app, so it runs in Chrome on ChromeOS with no installation. All processing happens on your device, in this browser tab.

It depends almost entirely on how much of the file is images. The size shown before you run it is a projection from the level you picked, roughly four-fifths of the original at Less, a bit over a third at Recommended, under a fifth at Strong, not a measurement of your particular document. The real figure appears after the run, and if it isn't good enough you can pick another level and go again without re-adding the file.

Every FernPDF tool processes files in your browser: read how the privacy model works, or verify it yourself in your network tab.
