On-device conversion
The app uses local WebKit extraction, local cleanup, and local export instead of routing your reading library through an external conversion API.
iPhone • iPad • Mac release
TheOneConvert keeps article conversion local, portable, and ready for release.
The native app converts supported article pages on-device, stores them locally for offline reading, and exports clean files without analytics, tracking SDKs, or an external conversion service.

On-device conversion, offline library storage, and export on iPhone, iPad, and macOS.
Core workflow
1Paste a public article URL
2Clean it into a reader-friendly view
3Keep it locally for offline reading
4Export in the format you need
Reader and library
Search, favorites, folders, and re-convert flows stay aligned across mobile and desktop.
Exports
Markdown, TXT, HTML, PDF, and EPUB are available from the same cleaned article.
Release scope
The release site now presents the app first and keeps the converter available as a web demo.
The native app stays centered on local conversion and privacy, while the existing site functionality remains useful as a quick “try online” path for public article URLs.
Portable exports
Save Markdown, TXT, HTML, PDF, and EPUB from the same cleaned article so the content moves cleanly into notes, archive folders, and e-readers.
Library and sync
Keep converted articles in a local library with search, favorites, and folders. Optional iCloud sync stays inside the user’s own Apple account.
The shipping app is designed around on-device behavior.
TheOneConvert stores saved articles and export preferences locally. Optional iCloud sync is limited to the user's own private Apple account data. The app does not ship with analytics, ad tracking, or third-party conversion services.
No account system
No analytics SDK
No tracking domains
No external conversion API
The web demo stays available without changing the app’s privacy model.
The online demo fetches the public URL you submit so it can build a one-off conversion response in the browser. The release site can use Vercel Analytics, but the native app itself still avoids analytics SDKs, ad tracking, and download counters.
No download counters
Website analytics only
No saved conversion history
Refresh clears the current result
If you need the fully local workflow, use the native app. If you just want to test a public article quickly, the demo below keeps the current converter online.
Across Apple platforms
The experience stays consistent from phone to desktop.
Reader behavior, export flow, and saved library management follow the same model on iPhone, iPad, and Mac, with platform-specific navigation where it makes sense.
iPhone and iPad support volume-button chapter navigation when chapter links exist.
macOS supports left and right arrow navigation plus mouse back and forward buttons when available.
The reader keeps Converted or Raw mode until the user explicitly changes it.
Exports default to Downloads and can remember a custom folder.
Library
Search, favorites, folders
Converted articles can stay in a local library with re-convert support and cleanup rules rather than living as disposable downloads.
Sync
Optional iCloud only
When enabled, sync uses the same Apple ID to share the saved library across devices. There is no separate account system.

This demo is best for quickly testing the conversion pipeline. For the fully local workflow and saved library, use the native app release.
