The WikiPlus image suite covers the full day-to-day visual workflow. Compress a photo before emailing it, enhance a blurry scan with AI upscaling, resize a picture for your website, crop to a specific aspect ratio, convert between JPG, PNG, WebP, and AVIF, or generate a QR code you can point a camera at. Every transform runs as WebAssembly inside your browser, so the original file never leaves your device or appears on a remote server log.

Every tool on this page runs entirely inside your browser. Nothing is uploaded to our servers, nothing is cached for later, and no account is required. Files are processed on your own device using WebAssembly modules and the open-source libraries that power each utility, which means confidential documents stay confidential — even if you disconnect from the internet after the page loads, most tools will still finish their job. Pick the utility you need below and start working straight away.

Frequently asked questions

What's the largest image I can process here?
The limit is your browser's available memory, comfortably about 100 megapixels on desktop (roughly a 12K photograph) and 30 megapixels on mobile. The tools stream data in chunks to avoid loading the entire file at once.
Does compressing a JPG to WebP lose quality?
WebP at quality 80 is visually indistinguishable from the original JPG in most cases, at roughly 65% the file size. The quality slider lets you push further down if you prioritise bandwidth over pixel-perfect fidelity.
Why is the AI upscaler slow on my laptop?
Upscaling runs a neural network locally in WebAssembly. On CPU-only machines, a 4× pass on a 2-megapixel image takes 10 to 30 seconds. A recent integrated GPU with WebGPU support typically finishes in under 5 seconds.
