What is Zapixal?
Zapixal is a free, privacy-focused online image compressor and format converter designed to process your files entirely inside your browser.
Unlike traditional cloud-based image converters that upload your images to remote servers, Zapixal leverages WebAssembly (WASM) and Web Workers to process all files 100% locally on your machine. Your sensitive photos, documents, and designs never leave your browser.
Key Features: 100% Client-Side Processing: Zero server uploads—complete data privacy and security.
Fast Compression & Conversion: Batch process images instantly with hardware-accelerated WebAssembly.
Multiple Format Support: Convert HEIC, WebP, PNG, JPEG, and AVIF formats seamlessly.
Works Offline: Once loaded, you can compress and convert images even without an active internet connection.
No File Size Limits: Process high-resolution images without restrictive server quotas or registration requirements.
Zapixal is a fast, lightweight, and private alternative to server-based converters like TinyPNG, ILoveIMG, and Convertio.
