Unfake.Js
Unfake.Js converts AI images into pixel art or SVG vector graphics locally in your browser — no upload.
For one-off cleanup of an AI-generated sprite, Unfake.Js is a sensible pick — no account, no install, and it keeps running offline after the first load. Take the v1.2.0 build (262 kB); the Rust/WebAssembly core replaced the slower, heavier JavaScript version. Volume work is where it stops: one image at a time, no batch queue.

Skip Unfake.Js if you need to process a folder of sprites in one run — it converts one image at a time with no batch queue, so anything above a handful of assets belongs in a desktop batch tool.
The itch.io listing is a name-your-own-price download, so cost is whatever you choose to pay rather than a metered plan — there are no seats or usage tiers to grow into. That makes it cheaper than any subscription pixel or vector converter for a solo artist doing occasional work, but it doesn't scale into a studio pipeline the way a paid batch tool with per-seat or per-asset pricing would.

What is Unfake.Js?
Unfake.Js — Unfake.Js converts AI images into pixel art or SVG vector graphics locally in your browser — no upload. Best for Pixel artists refining AI-generated sprites without uploading artwork, Game developers converting AI concept art into clean pixel or vector assets, Designers who need an SVG trace of an AI image without a per-trace fee. Free to use.
Unfake.Js (listed on itch.io as Unfaker by developer jenissimo) is a browser tool that turns an image into pixel art or a vector trace. The file never leaves your machine: the conversion runs client-side on WebAssembly builds of OpenCV and ImageTracer, so the tab keeps working offline once it loads. Pixel artists and game developers use it most often — AI-generated sprites and concept art often arrive soft-edged and over-coloured, and this is a fast way to force them back to a grid. Two modes cover the workflow. Pixel mode detects pixel size automatically or lets you set it by hand, with optional cleanup filters and colour-count limits for tightening a palette. Vector mode traces the image with adjustable noise filtering, palette quantisation, and stroke and curve controls. After processing, a palette editor lets you recolour without reprocessing, and a built-in magnifier lets you inspect individual pixels before you commit. The June 9, 2026 v1.2.0 release rewrote the processing core in Rust compiled to WebAssembly, which the developer says improves accuracy and speed and shrinks the download from 3.7 MB to 262 kB. A smaller v1.1.0 bug-fix build landed the day before. Inputs are PNG, JPG and WebP; outputs are PNG in pixel mode and SVG in vector mode, downloadable or copied to the clipboard as a PNG or raw SVG code. Presets give beginners a one-click path, while detailed sliders are there for advanced users. Positioning: this is a converter, not an editor, and it handles one image at a time. If you need batch processing, colour indexing across a spritesheet, or a scriptable pipeline, desktop tools belong in your stack. If you want a no-install utility that respects your files, Unfake.Js covers that niche well.

Behind the verdict
We'd reach for Unfake.Js at the awkward stage of AI asset work — the sprite exists but the edges are mush and the palette has 400 colours. Pixel mode with automatic size detection usually gets you most of the way; the colour-count limit finishes the job. Pick it when the file is sensitive or the machine is locked down. Local processing is the whole product here, and it's not a marketing line — the WebAssembly build genuinely runs offline once loaded. That matters for contractors on client machines and anyone under an NDA who can't upload artwork to a random web service. The vector side is the underrated half. Plenty of image-to-SVG services charge per trace or leave a watermark; here you get noise filtering and curve controls with no ceiling, and the clipboard export drops raw SVG straight into a design tool. Where it bites: one image per pass. Cleaning a 60-frame spritesheet means 60 round trips through the tab, and no amount of preset-tuning fixes that. There's also no batch queue, no API, and no CLI — if your pipeline is automated, this isn't in it. Setup isn't always frictionless. The itch.io page carries a 4.7/5 rating from 30 ratings, but an open community thread about OpenCV failing to launch has been running a while, so budget a few minutes the first time. The closest alternative is a desktop pixel-art editor with a trace plugin — more control, more setup, a real install. Against cloud vectorisers, Unfake.Js wins on privacy and price (it's name-your-own-price on itch.io). We'd keep it bookmarked for ad-hoc conversions rather than making it the centre of an asset pipeline.
Limitations
- Single-image workflow only — there is no batch queue, so a studio processing hundreds of sprites will find it tedious.
- It is a converter rather than an editor: you cannot draw new vector shapes, assemble scenes or do layer-based composition.
- Inputs are limited to PNG, JPG and WebP, and output is PNG in pixel mode or SVG in vector mode (or clipboard copy of the PNG / raw SVG code).
- At least one community thread on the itch.io page reports OpenCV failing to launch, so browser-specific problems are possible.
- The listing also shows two downloads, 1.1.0 (3.7 MB) and 1.2.0 (262 kB); the Rust/WebAssembly core lives in 1.2.0.

GeneratedReal-world workflow fit
Concrete scenarios for the personas Unfake.Js actually fits — and what changes day-one when you adopt it.
You generated a batch of enemy sprites and one has blown-out edges and stray colours. You open the Unfake.Js tab you loaded earlier (it still works offline), drag the PNG in, pick Pixel mode, accept the automatic pixel-size detection, set a colour-count limit to match your 16-colour palette, and check the result with the magnifier.
Outcome: A PNG sprite that fits your palette and drops into the engine without manual retouching — and the source image never left your machine.
You have an AI-generated contour illustration that needs to scale cleanly for print. You switch to Vector mode, dial up noise filtering to clear the artifacts, adjust palette quantisation and the stroke and curve controls, then copy the raw SVG code straight to your clipboard.
Outcome: Vector code you can paste into your design tool or hand to a developer without a file transfer or an export round-trip.
You can't install desktop software on the machine you're working from. You load Unfake.Js once in the browser, then work through a series of client images on a patchy connection, recolouring each result in the palette editor before exporting.
Outcome: Finished PNG or SVG deliverables produced entirely client-side, with no install and no upload of client artwork.
Use cases
- Clean jagged edges and stray pixels from an AI-generated sprite before importing it into a game engine
- Trace an AI-generated image into an SVG with noise filtering and stroke controls
- Reduce an AI-generated image to a tight retro palette with colour-count limits
- Inspect individual pixels with the magnifier to confirm artifacts are gone before exporting
- Keep client artwork entirely on your own machine with no upload step
- Trace contour art into a scalable SVG for use at other sizes
- Work offline on a laptop after the first page load
Setup time & first value
How long it actually takes to get something useful out of Unfake.Js — broken out by persona, not the marketing-page minute.
Roughly a minute to first output for anyone who takes the presets — the itch.io page is a single drag-and-drop interface with no account or install step. Expect a few extra minutes of slider tweaking in Vector mode if you need to tune noise filtering and stroke curves, and budget a little time for browser troubleshooting if OpenCV fails to launch.
Switching to or from Unfake.Js
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a desktop pixel-art converter: no import path — save your source PNG/JPG/WebP and drop it into the browser tab, then reuse your palette via the colour-count limit
- →From an AI image generator's built-in upscaler: keep the raw generation, load it in Unfake.Js, and use Pixel mode cleanup rather than the generator's smoothing
- ↗To a full vector editor: export the SVG from Vector mode and open it there for shape drawing, layering and composition
- ↗To a desktop batch tool: export PNGs from Pixel mode and queue them in the batch processor when your volume outgrows one-at-a-time conversion
