Noderail is a growing collection of free online utilities that run entirely inside your web browser. Nothing is uploaded: every tool processes your data locally with JavaScript and WebAssembly, so files never leave your device, there is no queue, no server-imposed size ceiling, and no copy left on someone else's disk afterwards.

What it covers

• PDF — merge, split, compress, rotate, sign, unlock, delete pages, add page numbers or a watermark, and convert to and from Word and JPG.
• Images — HEIC, WebP, AVIF and PNG conversion, compression, resizing, cropping, EXIF stripping, background removal, and passport/ID photo sizing for common formats.
• Video & audio — MP4, MKV, MOV, AVI and WebM conversion, trimming, muting and compression, powered by ffmpeg compiled to WebAssembly.
• Generators — QR codes (plain, WiFi, vCard, with logo), barcodes, invoices, receipts, favicons, email signatures and strong passwords.
• Calculators — mortgage, loan, car loan and lease, refinance, retirement, 401(k), debt payoff and more, each with a full amortization schedule.
• Hardware tests — keyboard, mouse, gamepad, microphone, webcam, speakers, monitor and dead pixel checks.

Why it is different

No account or sign-up is required, output carries no watermark, and nothing expires because nothing is stored. Tools keep working after the page has loaded even without a connection, and an optional Chrome extension bundles them for offline use.

The interface is available in English, Spanish, German, French and Russian. Any tool can also be embedded into a third-party website with a single iframe snippet.
