Preview any file attached to your Bkper books directly in the browser — no downloads required.
This app renders files in your browser from a direct URL. When an external integration (like the Google Sheets add-on or another app) links to a file, this app fetches it and displays it inline:
- Images — centered preview with a dark background
- PDFs — native browser viewer
- Text & JSON — readable inline display
- Other files — your browser handles preview or download automatically
A floating Download button lets you save the file with its original name whenever you need a local copy.
The app works with any file you've attached to a Bkper book, including:
| Type | Preview behavior |
|---|---|
| PNG, JPG, GIF, SVG, WebP | Inline image viewer |
| Native browser embed | |
| TXT, CSV, JSON, XML | Readable text display |
| Other formats | Browser-native preview or download |
Files Preview opens when you follow a file link from an external Bkper integration. The URL looks like:
https://files.bkper.app/books/{bookId}/files/{fileId}/{fileName}
If you're not signed in, you'll be prompted to authenticate first — then the file renders immediately.
No setup or configuration needed. It just works.
