Everything in the studio,nothing on a server
From byte-budget exports to batch zips — a complete image pipeline in the browser.
Squoosh-grade codecs
MozJPEG, AVIF, WebP, Oxipng, JXL, and QOI via WASM — the same engines that power Google Squoosh.
Full pipeline control
Resize modes, crop, rotate, flip, filters, and advanced codec parameters — with tooltips on every setting.
Presets you can own
Start from built-in presets, save your own, revert unsaved tweaks, or export and import pipeline JSON.
Batch processing
Queue multiple files, run one pipeline, and download everything as a zip with per-file size stats.
Privacy by design
Images never leave your machine. No accounts, no API keys, no server — just WASM in a tab.
Three steps.Zero uploads.
Open the studio, configure once, and run the same pipeline across your whole queue.
Drop your images
Add files or folders. JPEG, PNG, WebP, AVIF, HEIC, GIF, SVG, and more — decoded locally in a Web Worker.
Build your pipeline
Pick a preset, set a size budget, or tune format, resize, crop, and codec options across the Format and Transform tabs.
Process and export
Compare before and after, review byte savings and budget stats, then download files individually or as a zip.
Squoosh-grade engines,compiled to WASM
Every codec and resize kernel runs locally — no server round-trip.
