NeoFile

Download

Current release: v1.0.1. One recommended file for each system is below. The project site also hosts NeoFile web desk, which is the browser app. It is not the native iOS app.

System	Recommended file	What to expect
Browser, including iPhone	Web desk	Open the page. On iPhone, use Safari, Share, Add to Home Screen. The first open needs a network connection. Later opens can work offline until the browser removes the saved copy.
Android	NeoFile-1.0.1.apk	Open the APK. Android can ask you to allow that app to install unknown apps. Not a store install, and not zero steps.
Windows 64-bit	NeoFile_1.0.1_x64.msi	SmartScreen can say "Windows protected your PC" because the installer is not Authenticode-signed. NeoFile cannot clear that warning.
macOS Apple silicon	NeoFile_1.0.1_aarch64.dmg	Not notarized. Gatekeeper can block the app.
macOS Intel	NeoFile_1.0.1_x64.dmg	Same notarization limit as Apple silicon.
Linux x86_64	NeoFile_1.0.1_amd64.deb	sudo apt install ./NeoFile_1.0.1_amd64.deb. Depends on libwebkit2gtk-4.1-0, libgtk-3-0, and libayatana-appindicator3-1.

Other files on the same release, not the recommended install: NeoFile_1.0.1_x64-setup.exe, NeoFile_1.0.1_amd64.AppImage, and NeoFile-1.0.1-unsigned.ipa. The IPA is an unsigned device build, not a one-tap iPhone install, and not a simulator build. Inside that published file the bundle version is 1.0, build 1. iOS will not install it from Files.

Install notes

Web desk

The hosted page is the same editor UI, running in the browser. Add to Home Screen saves that web app. It does not become the native iOS or Android package. File picking uses the browser. The first visit downloads the page. Offline use starts after that save, and the browser can delete it later.

Android

The APK requests no INTERNET permission. The published v1.0.0 and v1.0.1 APKs were signed with two different throwaway keys, and both keys were discarded on the build runner. Android will refuse to install one over the other. A new key cannot make that update seamless. Recents and snapshots live in the app's private IndexedDB database neofile. Saving a document writes that file to a folder you pick; those files stay. The web desk is a separate browser copy and does not contain the Android app's snapshots. Keep the installed app if you still need those snapshots.

Windows

The MSI is the recommended installer. The exe is the same unsigned app. Closing the window hides NeoFile in the system tray. Quit from the tray menu. SmartScreen appears because the installer is not Authenticode-signed. These notes do not ask you to turn SmartScreen off.

macOS

Open the DMG and drag NeoFile to Applications. The app is not notarized. Gatekeeper can block it. These notes do not include a command to strip that protection. Use the web desk if you need a copy that does not go through Gatekeeper.

Linux

No Node, Rust, or SDK is required for the deb. Ubuntu 24.04 provides the three libraries named above. The AppImage is the other file: chmod +x NeoFile_1.0.1_amd64.AppImage and run it. Video playback in the AppImage needs gstreamer1.0-plugins-good on Debian and Ubuntu.

iOS

There is no free universal install of the native iOS package. The unsigned IPA has no provisioning profile. The free phone path is the web desk.

What it does

• Edit text and code, with syntax colors for JavaScript, TypeScript, JSX, Python, HTML, CSS, JSON, XML, Java, and Markdown.
• Edit CSV and TSV, including quoted commas.
• Edit spreadsheet values in xlsx, xlsm, and xls.
• View PDF with text selection and search.
• Preview Word as HTML plus extracted text. Export HTML is not a Word file.
• Preview PowerPoint as slide text and embedded pictures. Layout is not rendered.
• Play images, audio, and video. Save exports the original. There is no media editor.
• Tabs, split view, search, drag-and-drop, a folder tree with multi-select, and local snapshots.
• Light mode uses a coral accent. Dark mode is one tap and uses neon green. You can set a custom accent.
• Android: swipe between files in a folder, and an offline inbox for files received from the share sheet.

Known limits

SheetJS community edition does not recalculate formulas. Saving a workbook writes cell values and drops charts, pivot tables, macros, images, comments, and most formatting.

Mammoth’s Word preview can miss text boxes, comments, tracked changes, and complex layout. PowerPoint does not show slide positions, animation, charts, or SmartArt.

Sheets larger than 20,000 rows or 100 columns open as a download-only file. Auto snapshots skip payloads over 2 MB.

Privacy

NeoFile does not have an account, sync, or analytics. Fonts are bundled. The production page’s Content-Security-Policy does not allow ordinary web requests. Recent files and snapshots stay in on-device IndexedDB. Erase them from the Privacy panel. That does not delete the original files in your folders.

Build from source

Requirements: Node.js 22.
