Your Privacy is Guaranteed
We take your privacy seriously. Here's our guarantee:
- No Server Uploads: Your images are processed entirely in your browser using JavaScript and Web Workers.
- No Data Storage: We don't save, store, or keep any copies of your images. Ever.
- No Tracking: We don't track which images you convert or how you use our tools.
- Open Source: Our code is transparent. You can verify everything we claim.
Understanding Image Processing
Browser-Based vs. Server-Based Processing
Traditional image converters require uploading your files to remote servers. This creates privacy risks, adds latency, and limits file sizes. Pixly uses modern browser APIs (Canvas, Web Workers, and WebAssembly) to process images entirely on your device. The result is faster processing, unlimited privacy, and no dependency on internet speed after the initial page load.
The Technology Behind Pixly
Our image processing stack combines multiple technologies for optimal results:
- Pica Library: Professional-grade image resizing with Lanczos3 resampling for sharp, artifact-free results.
- RMBG-1.4 Model: State-of-the-art neural network for AI background removal, running locally via WebAssembly.
- FFmpeg.wasm: Industry-standard video processing engine compiled for browser use.
- jsPDF & PDF.js: Reliable PDF generation and parsing without server dependencies.
- pdf-lib: Powerful PDF manipulation library for merging multiple PDFs while preserving quality.
Understanding Image Formats
Choosing the right image format depends on your use case. JPG excels at photographs with its efficient lossy compression. PNG preserves every pixel perfectly, ideal for graphics and screenshots. WebP and AVIF offer modern compression that significantly reduces file sizes while maintaining quality. HEIC is Apple's format that combines excellent quality with small files but has limited compatibility. Understanding these tradeoffs helps you choose the optimal format for web performance, print quality, or cross-platform sharing.
Who Uses Pixly?
Comparison with Desktop Software
While professional software like Photoshop or Adobe Acrobat offers comprehensive editing capabilities, it requires expensive subscriptions, installation, and learning curves. Pixly focuses on the most common image and PDF tasks (conversion, resizing, cropping, background removal, PDF creation, and PDF merging), making them accessible instantly in any browser. No downloads, no accounts, no learning curve. For quick image and PDF tasks, browser-based tools are often faster than launching desktop applications.
Works Offline
After Pixly loads in your browser, most features work without an internet connection. The image processing libraries are cached locally, allowing you to convert, resize, and crop images even on airplanes or in areas with poor connectivity. Background removal requires the AI model to download once, then works offline for subsequent uses.
