Unfake.Js
Fix AI pixel art and vector images directly in your browser — no uploads, no installs.
For pixel artists and game devs who need to clean up AI-generated sprites without uploading sensitive work, Unfake.Js is a solid, privacy-first pick. It's fast after the Rust rewrite, genuinely free, and runs offline. But it's niche — buy it if you regularly convert AI images to pixel art or vectors; skip it if you only need it once or require batch processing.

About Unfake.Js
Unfake.Js (listed as Unfaker on itch.io) is a browser-based utility that cleans up AI artifacts in pixel art and vector graphics. Everything runs locally in your tab using WebAssembly versions of OpenCV and ImageTracer, so your images never leave your device. It's aimed at pixel artists, game developers, and designers who need to refine AI-generated work without sacrificing privacy or dealing with installs. After the initial page load, it works fully offline. The tool accepts PNG, JPG, and WebP inputs. You choose between two modes: Pixel mode offers automatic or manual pixel-size detection, optional cleanup filters, and colour-count limits to keep palettes tight. Vector mode gives you adjustable noise filtering, palette quantisation, and stroke and curve controls for tracing paths. A built-in palette editor lets you tweak colors post-processing, and a magnifier provides pixel-level inspection for precision work. You can export results as PNG (pixel mode) or SVG (vector mode), or copy the PNG or raw SVG code straight to your clipboard. The interface includes quick presets for beginners and detailed sliders for advanced users, so it scales from hobbyist to professional. The developer recently rewrote the core in Rust/WebAssembly (v1.2.0) for faster performance and better accuracy. Unfake.Js fills a specific niche: cleaning up AI artifacts in pixel art and vectors. It's not for photo editing or batch pipelines, and it has no cloud collaboration or API. For its intended scope, it's a privacy-focused, free tool that respects your data and works where other converters can't.
Behind the Verdict
Let's be honest: most image converters upload your files to a server, which is a non-starter if you're working on unreleased game assets or client work. Unfake.Js sidesteps that by running entirely in your browser with WebAssembly — your images never leave your machine. That's the core appeal, and it's why we'd reach for this over a random online converter. What's changed recently matters. The v1.2.0 rewrite moved the core processing from JavaScript to Rust compiled to WebAssembly. The development log promises faster performance and better accuracy, and early impressions from the itch.io community suggest noticeable speedups on larger images. If you tried an earlier version and found it sluggish, it's worth another look. Where it bites: this isn't a batch tool. You process one image at a time, drag-and-drop style. If you need to clean up 50 sprites in an afternoon, you'll be clicking a lot. And while the vector mode is competent — noise filtering, palette quantisation, stroke and curve controls — it won't replace Illustrator for complex illustrations. It's a focused utility, not a full design suite. Compared to Aseprite, which is the go-to for pixel art, Unfake.Js is different: Aseprite is a full editor for creating sprites pixel by pixel; Unfake.Js is a converter that takes AI output or existing images and makes them pixel-clean. They complement each other. If you already own Aseprite, Unfake.Js can be the front-end cleanup step; if you don't, it's a low-friction way to test the waters without installing anything. Pricing is name-your-own-price on itch.io — you can grab it for free, or throw a few dollars the developer's way. There's no subscription, no paywall for the core features. That's rare for a tool that does its job this well. If you work with AI pixel art

Real-world workflow fit
Concrete scenarios for the personas Unfake.Js actually fits — and what changes day-one when you adopt it.
You've generated a sprite sheet with an AI tool and need clean pixel art for your game.
Outcome: Load the image into Unfake.Js, choose Pixel mode, and use auto-detection to convert it into a clean, colour-limited sprite in under five minutes, then export as PNG.
You have AI-generated vector art with noise and want a clean SVG for a client project.
Outcome: Use Vector mode with noise filtering and palette quantisation to produce a clean SVG, then copy the code directly to your clipboard for use in your design software.
You want to clean up AI-generated pixel art but are concerned about uploading it online.
Outcome: Use Unfake.Js offline in your browser—no data leaves your machine, so your work stays private while you refine it.
