Chrome doesn't merge PDFs. Google Drive doesn't merge PDFs. Most Chrome extensions for merging redirect to web apps. The direct route through the web app is faster.
The flow
Open Chrome. Go to Flint's merge tool. Add PDFs via drag-drop or file picker. Reorder thumbnails. Click Merge. Combined PDF downloads.
Works on every OS that runs Chrome — Mac, Windows, Linux, Chromebook.
Source files from anywhere
Drag PDFs from Finder, Explorer, Files (Chromebook), or your file manager of choice. Or pick via the file dialog. Drive PDFs need downloading first — Drive's web UI doesn't drag-and-drop into other web apps directly.
Cleanup post-merge
Merged PDFs often need polishing. Reorder pages if the order isn't right. Delete unwanted pages for blanks. Rotate sideways scans. Compress for sharing.
FAQ
Is there a Chrome extension that does the same?
Several, but most are wrappers around web apps. Going direct removes a layer. Flint doesn't need an extension.
Will merge preserve form fields?
Standard form fields generally survive. Complex interactive forms with scripting may behave unpredictably. Test if forms matter for your use case.
Can I merge from Drive directly?
Not via the Drive web UI. Download files locally first, upload to Flint. After merge, upload result back to Drive if needed.
Five PDFs become one. Merge in Chrome, no extension.
