aiRaven is a growing collection of AI-powered browser utilities. Everything runs locally — no server, no sign-up, no data collection.
New tools added regularly — all free, all private.

Shrink images without quality loss
Compress JPEG, PNG, and WebP images entirely in your browser. Batch processing, custom quality settings, before/after comparison.
Unix timestamps ↔ human-readable dates
Convert Unix epoch timestamps to ISO 8601, UTC, and local time — or reverse. Supports seconds and milliseconds with live clock and clipboard copy.
Focus modes with ambient backgrounds
Immersive Pomodoro timer with five focus modes — Deep Work, Study, Creative, Meditation, and Exercise. Custom durations, browser notifications, and automatic phase switching.
Encode, decode & generate Base64 instantly
Encode text or files to Base64, decode Base64 back to text, or generate cryptographically secure random values. URL-safe mode, copy & download — all in browser.
Placeholder text for designs & mockups
Generate Lorem Ipsum text by paragraphs, sentences, or word count. Output as plain text or HTML. Classic opening toggle, copy to clipboard, and download included.
On-device instrumental music for any mood
Generate ambient instrumental music for focus, calm, creativity, energy, or sleep — entirely in your browser. Markov-chain melodies, mood models cached on-device, no streaming.
Prettify code without sending it anywhere
Format JavaScript, TypeScript, JSX, TSX, JSON, HTML, CSS, SCSS, Markdown, and GraphQL instantly in your browser. Powered by Prettier — your code never leaves your device.
Decode & inspect JSON Web Tokens
Decode any JSON Web Token to inspect its header, payload, and signature. Human-readable expiry and issued-at times, expired-token detection, and pretty-printed claims — all in your browser, nothing uploaded.
Create QR codes for any link or text
Generate high-resolution QR codes for URLs, text, Wi-Fi credentials, and more. Export as PNG or SVG. No tracking, no expiry.
Every aiRaven tool follows the same promise.
Your files are processed on your device using Canvas and WebAssembly. Nothing is sent to any server.
State-of-the-art ML models run locally via WebAssembly for background removal, face detection, and more.
No account required, no subscription, no hidden limits. Every tool on aiRaven is free to use, forever.
Tools download their models once, then work entirely offline. No internet needed after the first visit.
