Pages are copied unchanged rather than re-printed, so text stays selectable and scanned pages keep their resolution — Chrome’s print-to-PDF cannot promise either. The size-based mode answers Classroom and email caps directly; the bookmark mode turns a course reader into chapter files named after the bookmarks. Files above 200 MB open in big-file mode, which streams the document so even a low-memory Chromebook can split a huge scan by page count, though the size-based split needs the file loaded. Nothing is uploaded at any stage, and the original file on your device is never modified.
How it works
- Open Bindery in Chrome and drop the PDF into Split
- Choose every page, every N pages, at bookmarks, or under a size
- Download the ZIP of parts
Questions people ask
Can I split a PDF under a size for Google Classroom?
Yes. Choose “under a size” and type the limit; Bindery writes the fewest consecutive parts that each stay below it, checking the real bytes of every part. If a single page alone exceeds the limit, it becomes its own part and the result tells you.
How do I open the ZIP on ChromeOS?
Double-click it in the Files app — ChromeOS mounts ZIP archives like folders, so you can drag the parts out or open them directly in Chrome. Each part is named after the original with its page or part number. No extraction app is needed for that.
Does it work offline in class?
Once Bindery has loaded, yes. Install it from the Chrome menu and it opens from the shelf without a connection; splitting, merging, compressing and the other tools all run on the device, because there is no server involved in processing.
