Unfake.Js
Fix AI pixel art and vector images right in your browser.
A solid, privacy-first utility for cleaning up AI-generated pixel art and vectors. Its local processing and recent Rust rewrite make it fast and reliable, but it's a niche tool — great if you fit the use case, unnecessary otherwise.

About Unfake.Js
Unfake.Js is a browser-based utility that converts AI-generated images into clean pixel art or vector graphics. All processing happens locally on your machine via WebAssembly, so no uploads or server round-trips are required. This makes it an ideal tool for artists, game developers, and designers who need to refine AI outputs without compromising privacy. The tool supports PNG, JPG, and WebP input formats and offers two distinct modes: Pixel mode (with automatic or manual pixel-size detection, optional cleanup, and colour-count limits) and Vector mode (with adjustable noise filtering, palette quantisation, stroke and curve controls). A built-in palette editor lets you tweak colours after processing, and the magnifier provides pixel-level inspection. Unfake.Js is designed to be approachable for beginners (with quick presets) yet powerful enough for advanced users (with detailed sliders). Exports include PNG (pixel mode) and SVG (vector mode), plus clipboard support for copying PNG or raw SVG code. The entire tool runs offline after the initial load, making it reliable and fast. What sets Unfake.Js apart is its focus on fixing AI artifacts specifically — it's built for the growing ecosystem of AI-generated graphics. The developer has recently rewritten the core in Rust/WebAssembly (v1.2.0) for better performance and accuracy. While it's a niche tool, it fills a clear gap for anyone working with AI pixel art or vector images.
Behind the Verdict
Unfake.Js excels at a very specific task: converting AI-generated images back into clean pixel art or vector graphics. The local processing (via WebAssembly) is a standout feature — no data ever leaves your machine, which is rare for AI-adjacent tools. The two modes (Pixel and Vector) are well-implemented with sensible defaults and advanced sliders for fine-tuning. The magnifier and palette editor add polish. However, it processes one image at a time with no batch mode, so it's not for heavy workflows. The paid support is minimal given the name-your-price model. Overall, it's a well-executed niche tool that solves a real problem for pixel artists and game developers.

Real-world workflow fit
Concrete scenarios for the personas Unfake.Js actually fits — and what changes day-one when you adopt it.
You generate a sprite with an AI image generator, but the edges are jagged and the palette has too many colours.
Outcome: You drag the PNG into Unfake.Js, switch to Pixel mode, set a colour limit (e.g., 16 colours), enable cleanup, download a clean sprite ready for your game.
You have an AI-generated background image you want to convert into a vector asset that scales.
Outcome: Load the image, switch to Vector mode, adjust noise filter and stroke curves, export as SVG, and import directly into your game engine.
You want to create a pixel-art icon from a photo but don't have dedicated software.
Outcome: Upload the photo, use Pixel mode with automatic detection, tweak colors with the palette editor, copy to clipboard, and paste into your design tool.
Use Cases
- Clean up jagged edges from AI-generated pixel art for game sprites
- Convert AI vector outputs into clean SVG with adjustable noise filtering
- Reduce colour palette of AI images to fit retro game limitations
- Inspect pixel-level artifacts using the built-in magnifier before export
- Generate polished vector traces from AI-generated contour art
Limitations
- The tool processes one image at a time with no batch mode.
- It relies on WebAssembly, so initial load may be slower on older machines.
- The free/name-your-price model means no paid support or advanced features.
