Free local tools
Resize, compress, convert, strip metadata
The always-free path handles the tedious work without touching a server or asking for a payment decision first.
Browser-only image processing
The only image tool that physically cannot see your files.
Cropbox keeps uploads out of the equation. Resize, compress, strip metadata, remove backgrounds, and upscale inside the browser with WebGPU and WASM, while Phoenix handles only auth and optional ad-removal access.

Why teams switch
Privacy is no longer a policy promise. It is the runtime model.
Sensitive assets stay local
Medical images, launch decks, and legal docs never transit a Cropbox server.
Unlimited local edits
Traditional tools pay GPU cost per request. Cropbox pays once when the app ships.
Offline after warmup
Cache the app shell and model weights once, then keep working without a connection.
AI operations
Free AI where the browser does the heavy lifting
Background removal, upscaling, and object cleanup stay local, so the product can stay free without metering every operation.
Batch workflows
A real workspace, not a one-off utility
Presets, batch export, quality checks, and platform-ready outputs sit behind one consistent editor shell.
Workflow
From drag-and-drop to export in four clean steps.
The product flow is simple because the architecture is simple: the browser owns image data, the server only owns account and unlock state.
01
Drop a file
Import from disk, paste a screenshot, or pull from the camera without leaving the app shell.
02
Detect capabilities
Cropbox chooses WebGPU first, then falls back to WASM when the machine needs it.
03
Process locally
All editing stays on-device. Go offline if you want. The pixels never leave the tab.
04
Export for the channel
Ship WebP, AVIF, JPG, or PNG with social presets and batch-ready output.
Trusted workflow
"We stopped asking designers to upload sensitive client assets into random SaaS tools."
"Cropbox made privacy a non-issue. Our team can batch-resize product launches, strip metadata, and prep campaign shots without clearing legal every time."
