Three PDFs from Drive, one report needed for school or work. ChromeOS Files doesn't merge. Drive doesn't merge. The Play Store wants subscriptions. The browser the Chromebook already runs has the answer.
The flow
Open Chrome. Go to Flint's merge tool. Add PDFs from Files or Drive (drag and drop, or file picker). Reorder thumbnails. Hit Merge. Combined PDF downloads.
Works on every Chromebook with current Chrome. School-issued or personal.
Sourcing from Drive
Drive PDFs aren't directly draggable into Flint from drive.google.com — download them first to Files, then upload to Flint. After merge, upload the result back to Drive if needed. Two manual hops but no API.
Polishing the result
Merged file usually needs cleanup. Reorder pages for final ordering. Delete blank pages the originals had. Compress before sharing if it's large.
FAQ
How many PDFs can I merge on a Chromebook?
Dozens. Practical limit is total file size — large merges (hundreds of MB) work but are slower over school Wi-Fi. For everyday use, no real limit.
Will Drive bookmarks survive the merge?
Internal links within source PDFs preserve through Flint's merge. Drive-specific metadata (sharing, comments) is per-file and doesn't transfer — that's a Drive feature, not a PDF feature.
Can I merge from school Drive accounts?
Yes, if your school allows file downloads. Some restrict downloads — in that case, work entirely in Drive's native tools (which don't merge) or ask IT to allow Files access.
Five PDFs for one report. Merge them in Chrome and submit one.
