No upload endpoint exists. Images are processed in WebAssembly sandboxes running locally.How It Works
Four steps from raw file to production-ready optimized asset.
01
Drop Your Image
Drag any image file onto the workspace. Supports JPEG, PNG, WebP, AVIF, GIF, SVG, PSD, HEIC, RAW formats, and more.
02
Choose a Codec & Settings
Select MozJPEG, WebP, OxiPNG, or AVIF. Tune quality, quantization, subsampling, progressive mode, and resize dimensions.
03
Compare in Real Time
Drag the split slider to compare original and output side-by-side. The size reduction and quality delta update instantly.
04
Download or Batch Export
Save the optimized file instantly. Or use Batch Mode to process a folder and download all results as a ZIP archive.
Everything You Need to Optimize Images
From single-file compression to enterprise batch pipelines — one tool does it all, without leaving your browser.
MozJPEG / OxiPNG / AVIF / WebP Codecs
Use the same native C/C++ codecs compiled to WebAssembly that power the original Google Squoosh — trellis quantization, progressive rendering, lossless modes, and custom subsampling.
100% Client-Side Privacy
Images never leave your device. There is no upload endpoint, no cloud queue, and no third-party image API. Compression runs in isolated WebAssembly sandboxes inside your browser tab.
Real-Time Split-Preview Comparison
Drag the split slider between the original and compressed output to compare quality at any pixel. Side-by-side mode, zoom, and pan also supported.
Batch Mode — Process Hundreds of Images
Drop a folder of assets. Batch mode auto-compresses each file using your selected codec and settings, then packages everything into a single ZIP for download.
80+ Professional Tools
Beyond compression: resize with aspect lock, crop to ratio presets, rotate and flip, watermark, borders, AI enhance/upscale/denoise, encryption, EXIF inspector, QR codes, favicon generator, and more — all real and working.
Live RGB Histogram + Dominant Palette
Analyze luminance distribution across red, green, and blue channels in real time. Extract the top 8 dominant colors with HEX, RGB, and WCAG contrast ratio values.
