Only embedded images are resampled and re-encoded, and only when the result is at least 8% smaller; text is never rasterized and duplicated resources are stored once, so compressing twice does no harm. The job runs in a background worker and can be cancelled without counting against the day. A memory guard at intake matters more on a 4 GB Chromebook than on a desktop: it tells you what the device can hold before a large scan is loaded, and files above 200 MB should be split first. Installed from Chrome’s menu, Bindery works offline and saves straight to a folder.

How it works

  1. Open Bindery in Chrome and drop the PDF into Compress
  2. Read the three computed sizes on the cards
  3. Download the level that fits your limit

Questions people ask

How much smaller will my file get on a Chromebook?

The same as anywhere else — the engine is identical — and it depends on the images inside. Bindery measures instead of guessing: the three sizes shown are the real results computed on your Chromebook. Photo decks and scans shrink dramatically; text-only files barely move.

Is it slow on a cheap Chromebook?

Compression is image decoding and re-encoding, which a modest processor handles in seconds for ordinary documents and under a minute for a long scan. The work runs in a background worker, shows progress, and can be cancelled; nothing waits for an upload or a server queue.

Where does the compressed file go?

To your Downloads folder, or to Google Drive if that is where Chrome saves; with Bindery installed from the Chrome menu you can pick a folder once and every result lands there. The original is left untouched, so keep it until you have checked the result.
