Automatic updates on every device

• Web app and iPhone home screen: checks every 30 minutes and whenever you come back to it, then shows New version ready, reload with What's new.
• Windows, macOS, Linux (v1.2.0+): signed updates from GitHub Releases (latest.json). A gold card says Update ready: vX.Y.Z with Install now, Later and What's new; the release notes show before installing, the signature is verified, and the app relaunches. One-click rollback to the previous version, also offered if a new version fails to start.
• Android (v1.2.0+): checks the newest release, downloads the APK (only on Wi-Fi by default), verifies it is OpenFile, newer and signed with the same key, and opens the Android installer. Users of the v1.1.0 APK uninstall once, because v1.1.0 used a temporary key.
• Settings, Updates: current version, last checked, Check now, Stable or Beta channel, check on launch, daily, weekly or off, auto install (off by default), remind me tomorrow or next week, skip a version.
• New tools between releases: the apps can load the newer hosted web version inside the app (Ask, Always or Never), with the built-in copy as the offline fallback.

Full details, safety notes and the maintainer release steps: docs/INSTALL.md, Updates.

Build the apps yourself (contributors)

The desktop app is Tauri v2 in desktop/, the mobile apps are Capacitor 8 in mobile/. Both wrap the same dist/ web build.

npm run app:desktop       # Windows, macOS or Linux installer for your OS (needs Rust)
npm run app:desktop:dev   # desktop dev window
npm run app:android       # debug APK (needs JDK 21 and the Android SDK)
npm run app:ios           # syncs and opens the Xcode project (macOS)
npm run app:assets        # regenerate icons, maskable icons, screenshots and splash screens

Run node scripts/bump-version.mjs 1.3.0 and node scripts/changelog.mjs --version v1.3.0 --write, push a tag like v1.3.0, and .github/workflows/release-apps.yml builds Windows, macOS (universal), Linux, Android and the iOS Simulator app, then attaches them to the GitHub Release with the signed update feed. Code signing for Windows, macOS, Google Play and the App Store needs the owner's certificates; see docs/INSTALL.md.

✨ Why OpenFile

🔒 Private by design Everything runs on WebAssembly, Canvas, Web Audio and Web Workers inside your tab. There is no upload endpoint, your files never touch a server.	⚡ Instant No upload queue, no download wait. Most jobs finish in milliseconds on your own CPU/GPU, and the PWA keeps working offline after the first visit.	🤖 On-device AI OCR PDF · Background Remover · Image Upscaler · Blur & Redact Image · Audio Transcriber, plus captioning, object detection, depth maps and semantic search. All run locally via WASM / WebGPU in background Web Workers, so the page never freezes.
♾️ No limits No file-size caps, no daily quotas, no watermarks, no account. Free forever under MIT.	🔁 Batch pipelines Chain steps into reusable recipes in the Workspace and process hundreds of files in one go, then grab a single ZIP.	💎 Crafted UI Command palette (Ctrl/⌘ + K), smart file drop, dark & light themes, favorites, recents and a fully responsive layout.

🆚 OpenFile vs. typical upload-based tools

	OpenFile	Typical upload-based tools
Where your file is processed	🟢 Your device (browser tab)	🔴 A remote server
Upload / download wait	🟢 None	🔴 Every file, both ways

🔁 Workspace, batch pipelines

The Workspace is a batch pipeline studio. Wire steps together on a node canvas (or a simple list), drop a folder of mixed files, and run it on hundreds of files at once. Branch, merge, pause, retry, then grab one ZIP. All of it runs in your tab, nothing is uploaded.

• One component per tool at src/tools/<category>/<slug>.tsx, discovered with import.meta.glob and code-split automatically, the homepage stays light even with 590 tools.
• Heavy engines load on demand (ffmpeg core, OCR language data, AI weights) and are cached by the browser and the service worker.
• Zero-upload guarantee: the optional Vercel functions (/api/health, /api/fetch-page, /api/meta) only ever receive a URL you type, never a file.

📦 Packages

OpenFile is published on GitHub Packages in two forms. Both are built and tested by .github/workflows/publish-packages.yml for every release.

Package	What it is	Get it
ghcr.io/aniruddhaadak80/openfile	Container image, linux/amd64 and linux/arm64, non-root, signed with cosign, with SBOM and build provenance	docker pull ghcr.io/aniruddhaadak80/openfile
@aniruddhaadak80/openfile	npm CLI that serves the full app from your machine, offline	npx @aniruddhaadak80/openfile

Docker

docker run -d --name openfile -p 8080:8080 ghcr.io/aniruddhaadak80/openfile:latest
# open http://localhost:8080

Image tags: latest, the full version (1.2.0), the minor line (1.2), the major line (1) and the commit (sha-<7 chars>). Pin a version or a digest in production.

Docker Compose

curl -O https://raw.githubusercontent.com/aniruddhaadak80/OpenFile/main/docker-compose.yml
docker compose up -d

npx

GitHub's npm registry needs a token even for public packages. Create a personal access token (classic) with only the read:packages scope, then add two lines to ~/.npmrc:

@aniruddhaadak80:registry=https://npm.pkg.github.com
//npm.pkg.github.com/:_authToken=YOUR_TOKEN

npx @aniruddhaadak80/openfile                 # serves http://localhost:5173 and opens your browser
npx @aniruddhaadak80/openfile --port 8080 --no-open
npx @aniruddhaadak80/openfile --host 0.0.0.0  # share on your local network

Verify the image signature:

cosign verify ghcr.io/aniruddhaadak80/openfile:latest \
  --certificate-identity-regexp '^https://github.com/aniruddhaadak80/OpenFile/' \
  --certificate-oidc-issuer https://token.actions.githubusercontent.com

Settings, headers, reverse proxies and Kubernetes: docs/SELF_HOSTING.md.

☁️ Self-hosting

OpenFile is a static site. Host it anywhere that serves files and rewrites unknown routes to index.html.

▲ Vercel (recommended, includes the optional API routes)

1. Import the repo on Vercel, framework (Vite), build command and output dir are read from vercel.json.
2. Deploy. SPA rewrites, /api/* functions, immutable asset caching and security headers work out of the box.

🐙 GitHub Pages (static mirror)

1. Fork the repo and push to main, .github/workflows/deploy-pages.yml runs npm run build:pages and publishes dist/ to the gh-pages branch.
2. Settings → Pages → Deploy from a branch → gh-pages / root (one-time).
3. Live at https://<you>.github.io/OpenFile/. Every tool works; only the URL mode of HTML → PDF needs the Vercel API.

Renamed the repo? Change VITE_BASE=/OpenFile/ in the build:pages script to match.

🐳 Docker (prebuilt image, any server)

Use the published container image, ghcr.io/aniruddhaadak80/openfile. It is multi-arch, runs as a non-root user and listens on port 8080:

docker run -d --name openfile -p 8080:8080 ghcr.io/aniruddhaadak80/openfile:latest
# then open http://localhost:8080

Pinned versions, Compose, Kubernetes, reverse proxies and signature checks are in docs/SELF_HOSTING.md.

📦 Any static host (Netlify, Cloudflare Pages, S3, your own server)

npm run build      # outputs dist/
npx serve -s dist  # quick local check with SPA fallback

Upload dist/ and make unknown routes serve index.html. For a sub-path, build with VITE_BASE=/your-path/ npx vite build.

🛡️ Security and quality

Check	What it does
CodeQL	Static analysis of the TypeScript app and the workflows on every push. Results show under Security, Code scanning.
Dependabot	Weekly grouped updates for npm and GitHub Actions, with licence-safe pins.
Security fixes	Attribute escaping in the ODT viewer, CAD to SVG and PDF reader print. The PDF embed preview only loads web addresses, paths and local files.
Signed releases	Desktop updates are verified against the OpenFile signing key, Android APKs against the release certificate, and the container image is signed with cosign.
scripts/check-parity.mjs	Every tool, studio and blog post must ship the same assets as the older ones: preview video, poster, icon, docs page and README row.
scripts/readme/check-readme.mjs	Runs before every build and fails if this README's tool or category counts drift from src/tools/registry.ts.

Found a security issue? Please open a private security advisory instead of a public issue.

• The one hard rule: keep everything client-side, PRs that upload user files will not be merged.
• Heavy libraries must be dynamically imported inside handlers so each tool chunk stays small.
• After adding a tool, run npm run docs:catalog to refresh this README, then npm run readme:check and node scripts/check-parity.mjs.
• Add a screenshot or GIF for UI changes. Full conventions: docs/TOOL_GUIDE.md · CONTRIBUTING.md.
• Found a bug or want a tool? Open an issue.

❓ FAQ

Are my files really never uploaded?

Yes. Files are read into memory by your browser and processed with WebAssembly, Canvas and Web Audio inside the tab. There is no upload endpoint in the code. Open DevTools → Network while using any tool to see for yourself. The only server routes are optional and accept a URL you type (for HTML → PDF and link previews), never a file.

Is it actually free? What's the catch?

No catch. Because your device does the work, there are no server costs to recover, so no paywall, no watermark, no quota and no account. The code is MIT-licensed.

Does it work offline?

Yes. OpenFile is an installable PWA. After the first visit the app shell is cached; engines such as ffmpeg, OCR language packs and AI models are cached the first time you use the tool that needs them.

How big can my files be?

There is no artificial cap, the limit is your device's memory. Very large videos or PDFs with hundreds of pages work best on a desktop browser.

Why is the first run of an AI or video tool slower?

The engine (for example ffmpeg core or model weights) is downloaded once and then cached. Later runs start instantly. WebGPU-capable browsers run the AI tools faster.

Which browsers are supported?

Capability	Chrome / Edge	Firefox	Safari
PDF, image, dev & text tools	✅	✅	✅
Video / audio (ffmpeg.wasm)	✅	✅	✅
AI tools (WebGPU fast path)	✅	⚠️ WASM	⚠️ WASM
Screen recorder	✅	✅	✅ 16+
QR scanning (BarcodeDetector)	✅	⚠️	⚠️

Check your own browser on the in-app /status page.

Can I link straight to a tool?

Yes, every tool has its own URL: https://openfile-studio.vercel.app/<slug>, for example /merge-pdf or /background-remover. Categories live at /category/<id>.

Can I self-host it for my team?

Absolutely, see Self-hosting. It is a static build, so any static host, an internal web server, or the container image above works.
