Two New Tools — Batch Background Removal and AI 4K Upscale

Making game assets involves more than generating sprite sheets — sometimes you need to strip backgrounds from a pile of images, or push a finished image to a higher resolution. This update adds a tool for each: Batch Background Remover and AI 4K Upscale. Both are live in the workspace now.

Batch Background Remover — many images at once

Sometimes it's not one character or icon that needs its background removed — it's dozens. Instead of uploading and processing them one at a time, the new Background Remover tool queues up a whole batch and works through it in order.

The flow is simple: drag or select multiple images (PNG/JPG/WebP, up to 30 files, 25MB each) and they land in a queue. The "Detail protection" slider balances preserving fine detail against cleaning up leftover background residue, and if you're on a slower machine, switching "Processing mode" to "Speed first" swaps in a lighter model for faster results. Hit start and the queue processes one image at a time; download results individually or grab everything as a ZIP. Not happy with a result? Click any finished image to open the cutout editor and touch it up by hand.

It runs in your browser and is free — log in and use it as much as you like, no credits spent.

AI 4K Upscale — enlarge and re-detail

The usual way to bump up an image's resolution is to stretch it and apply sharpening, which just hides the blur without adding detail that wasn't there. AI 4K Upscale works differently: it enlarges the image while an AI model regenerates fine detail. It's a generative upscale, not interpolation, so even a modest-resolution source comes out noticeably crisper.

To use it, upload one image and you'll see the original and result side by side. The "Re-detailing strength" slider controls how faithful the result stays to the source versus how much new detail gets generated — lower for closer to the original, higher for a bolder re-render. Hit "Upscale to 4K" and the result lands in under a minute; click either image to view it full-size.

This tool costs 3 credits per run. We cap the target resolution around 7 megapixels — close to full 4K — to keep the cost reasonable.

Get started

Both tools live in the workspace tabs, or under the "Workspace" menu in the nav. Background removal is free, so try that first; reach for the upscaler when you want to push a finished result to a higher resolution.
