Notion treats PDFs as embedded files. You can preview them, but Notion's editor handles text on pages, not inside PDFs. For actual PDF edits, the flow is download, edit, re-embed.
The flow
Click the embedded PDF in Notion. Hit the download arrow (or the file menu → Download). File goes to Downloads.
Open Flint in another browser tab. Drag the file in. Edit, sign, or compress. Download the edited version. Back in Notion, delete the old embed and drop the new file in the same spot (or use the file menu → Replace).
Versioning in Notion
Notion's page history tracks changes including file replacements. To preserve a clear audit, name your edited file descriptively (e.g. 'Contract_signed_v2.pdf') so the version difference is obvious in history.
Linked vs. embedded
Notion supports both — embedded files live in Notion's storage, linked files point to external URLs (Drive, Dropbox). For linked files, edit the source in the cloud service and Notion's preview updates automatically when refreshed. Easier than embed replacement for frequently-edited PDFs.
FAQ
Can Notion edit PDFs natively?
No. Notion's editor is for Notion pages, not PDFs. PDFs are embedded files — viewable and downloadable but not editable inside Notion.
Will replacing the embed break links from other pages?
Links to the Notion page survive the file replacement. Direct links to the file URL change when the file is replaced. For frequent edits, link via URL rather than embed.
Are there Notion integrations for PDF editing?
Some integrations exist (PDF embeds via third parties) but native editing isn't available. The download-edit-replace flow is the universal answer.
Notion holds PDFs, Flint edits them. Replace the embed; you're done.
