Everything you need to remove backgrounds
AI-powered detection
An on-device AI model automatically detects and separates subjects from backgrounds with high accuracy — no manual masking required.
100% private, runs locally
The AI model runs entirely in your browser via WebAssembly. Your images never leave your device — no uploads, no cloud processing. Once the model is cached after your first use, it keeps working without a network connection.
Transparent PNG output
Download with a transparent background to layer images over any surface or use in design tools. Or add a solid colour fill before exporting.
Batch processing
Remove backgrounds from multiple images in one go. Download each result individually or bundle everything into a ZIP archive.
Custom background colours
Replace the transparent background with any solid colour — white for e-commerce, black for dramatic contrast, or any custom hex colour.
Three steps to a transparent background
- 1
Upload your image
Drag and drop one or more images onto the page, click to browse, or paste from your clipboard. Supports JPG, PNG, WebP, and HEIC files up to 100 MB each.

AI removes the background automatically
The AI model runs entirely in your browser — nothing is uploaded. On your first use, the model (~40 MB) is downloaded once and cached. Processing takes a few seconds per image depending on your device.

Download with transparent background
Your image is ready with a transparent background. Download as PNG to keep transparency, or choose a background colour to export with a solid fill. Batch download as a ZIP for multiple images.

Frequently asked questions
Is PixelTools background remover free?
+
Yes, completely free with no limits. Remove backgrounds from as many images as you want — no subscription, no credits, no account required.
Are my images uploaded to a server?
+
No. PixelTools removes backgrounds entirely in your browser using an AI model that runs locally via WebAssembly. Your files never leave your device — there is no server upload and no data stored.
How does it compare to remove.bg?
+
remove.bg charges ~$0.10 per image and caps free downloads at low resolution. PixelTools is completely free, unlimited, and full-resolution. The trade-off is that the AI model runs on your device rather than a cloud GPU, so processing takes a few seconds instead of under one second.
How accurate is the background removal?
+
The AI works very well for most subjects — people, products, animals, and objects against distinct backgrounds. For very fine details like individual hairs or transparent objects, results may need manual refinement in an editor like Photoshop or GIMP.
What background colours can I use?
+
Download as PNG for a fully transparent background, or choose any solid colour — white, black, or a custom hex colour — to replace the transparent areas before downloading.
What image formats are supported?
+
PixelTools accepts JPG, PNG, WebP, and HEIC as input. Output is always PNG to preserve transparency — or PNG with a solid background colour fill if you choose one.
