You edit a PDF in Flint, you've got the corrected file in Downloads, and you need it back where it came from — Drive, Dropbox, OneDrive, iCloud, Box. The flow is identical for all of them: upload.
The universal flow
Edit the PDF in Flint. Download the result. Open the cloud service in another browser tab. Drag the file in (or use the upload button). Done.
Drive: drive.google.com → drag file in. Dropbox: dropbox.com → drag file in. OneDrive: onedrive.live.com → drag file in. Box: box.com → drag file in. iCloud Drive: icloud.com → Drive section → upload.
Replace vs. save as new
If you upload with the same filename, most services keep version history (Drive, Dropbox Pro, OneDrive). The old version is preserved; new uploads become the latest.
For explicit versioning, save with a new name (e.g. 'Contract_v2.pdf', 'Contract_signed.pdf'). Easier to see what's what later, especially in shared folders.
Mobile workflows
On iPhone or Android, after downloading from Flint, use the share sheet to send straight to your cloud service. iOS: share → Save to Files (pick the cloud location). Android: share → Drive/Dropbox/etc. Both skip the manual upload step.
Sync delay
Cloud sync isn't always instant. After uploading, give it 10–30 seconds for the file to propagate to other devices viewing the same account. Most providers are fast; a couple of edge cases (very large files, weak connections) take longer.
FAQ
Will Flint connect to my cloud directly?
Not currently via OAuth. The manual download-upload flow works across all clouds without granting Flint access to your accounts.
What about conflict resolution if two people edit at once?
Most clouds detect conflicts and create copies (e.g. 'Contract (1).pdf'). For team workflows, agree a process (one person edits at a time, or always save as new versions) to avoid conflicts.
Can I edit directly in the cloud without downloading?
Not for true text edits. Some services offer in-place annotation (Drive, Dropbox annotation tools) but not text editing. For text edits, the download-edit-upload flow is the universal answer.
Edit anywhere, save anywhere. Flint covers the edit; your cloud handles the storage.
