Our Mission

We believe that converting images should be simple, fast, and most importantly, private. That's why we built Convertio - a tool that processes all your images directly in your browser, without ever uploading them to any server.

Why Choose Us?

100% Private: Your images never leave your device. All processing happens locally in your browser.
Lightning Fast: No upload time. No waiting for servers. Instant conversions.
Completely Free: No hidden fees, no premium tiers, no limitations on conversions.
No Account Required: Start converting immediately. No sign-up, no email verification.
Offline Capable: Install as a PWA and use it even without internet connection.

Supported Formats

We support a wide range of image formats:

JPG/JPEG: Perfect for photographs and complex images
PNG: Ideal for images with transparency
WebP: Modern format optimized for the web
GIF: For animations and simple graphics
BMP: Uncompressed bitmap images
TIFF: Professional-grade image format
SVG: Scalable vector graphics wrapper
ICO: Favicon and icon format
HEIC/HEIF: iPhone photo format (read support)

How It Works

Our converter uses modern web technologies including HTML5 Canvas API, Web Workers, and the FileReader API to process images entirely within your browser. This means:

Your files are never uploaded to any server
Processing speed depends only on your device, not your internet connection
You can convert images even when offline
There's no risk of your images being stored or shared

Technology

Built with modern JavaScript (ES6+), our application uses a modular architecture for easy maintenance and continuous improvement. We use:

JSZip: For creating ZIP files of batch conversions
heic2any: For reading HEIC/HEIF files from iPhones
Service Workers: For offline functionality
Progressive Web App: Install and use like a native app

Open Source

We believe in transparency. Our code is open for inspection, ensuring you can verify that your images truly stay on your device. We have nothing to hide.
