Pixelate Image - Turn photos into blocky pixel art, right in your browser

I built Pixelate Image because I kept needing to add pixel effects to screenshots and reference photos, but didn't want to fire up Photoshop every time. The tool runs entirely in your browser using Canvas API – your images never leave your device. You get a slider for block size, a before/after comparison button, and export options for PNG/JPG/WebP. It's intentionally simple: no layers, no filters, just the pixelation workflow. If you need to turn a photo into blocky pixels quickly, this should do the job. Would love to hear what you think or what use cases I missed!
