PNG Snap is an online tool that removes the background from your own images and gives you a transparent PNG. It is not a stock PNG library: there are no images to browse or download, only the ones you upload.
This page lists what PNG Snap does today. When something changes, this page is updated and the date above changes with it.

Pricing and limits
- PNG Snap is free to use. There are no paid plans yet.
- The PNG Maker has no daily limit when it runs in your browser. Cloud processing, used on phones and browsers that can't run the model, includes 3 free images per visitor per day; if processing fails, that image is not counted.
- The Remove White Background tool and the transparency checker run in your browser and have no daily limit.
Signup and watermarks
- No account is needed for any tool.
- Downloads never carry a watermark, including on the free plan.
Formats and output size
- You can upload JPG, PNG and WebP images up to 25 MB. HEIC files from iPhones are not accepted directly; export or share them as JPG first.
- Every download is a PNG with an alpha channel: background pixels are actually transparent, not drawn as a checkerboard.
- PNG Maker in your browser: the output has the same pixel size as your image.
- PNG Maker in the cloud: our AI provider accepts images up to 4096 px on the longest side, 16 megapixels and 5 MB. Larger images are scaled down in your browser before upload, so the result may be smaller than your original. Images smaller than 256 px on the short side are scaled up. The exact output size is shown before you download.
- Remove White Background: the output has exactly the same pixel size as your image.
Where your image is processed
PNG Maker in your browser (most computers)
On computers whose browser supports WebGPU with 16-bit floats (recent Chrome and Edge on Windows and macOS), the PNG Maker runs an AI model on your own device:
- The model (about 108 MB) and its runtime (about 27 MB) download once from pngsnap.com and are cached by your browser.
- Your image is processed on your device and is never uploaded.
- If the model can't start on your device, PNG Snap offers cloud processing instead and tells you before anything is uploaded.
PNG Maker in the cloud (phones and other browsers)
Your image is uploaded to our server and passed to our AI processing provider, kie.ai, which runs Recraft's background-removal model.
- PNG Snap does not keep a copy of your image or of the result on its own servers.
- kie.ai states that uploaded files are deleted 24 hours after upload.
- kie.ai has not published how long it keeps processed results, or whether uploaded images may be used to improve models. If that matters for an image (for example, a legal signature or a photo of a child), use the Remove White Background tool instead when the background is plain, because it never uploads anything.
Remove White Background and the transparency checker (in your browser)
The image is read and processed by your own browser. It is not sent to PNG Snap or to anyone else.
Commercial use
You may use the images you create with PNG Snap in personal and commercial projects. PNG Snap does not claim any rights to your images. You are responsible for having the rights to the image you upload: a transparent background does not grant rights to a logo, photo or artwork you do not own.
How background removal works
- PNG Maker uses an AI segmentation model that finds the main subject in a photo. It works on any background, including busy ones. In the browser it uses BiRefNet_lite (MIT license), adapted to run on WebGPU; in the cloud it uses Recraft's background-removal model.
- Remove White Background uses a color-to-alpha method: it removes one color you choose and turns partly blended edge pixels partly transparent. It is predictable on plain backgrounds, but it does not "understand" the subject.
Known limitations
- Fine hair and fur on a busy background may lose detail or keep traces of the background.
- Glass, smoke, water and other semi-transparent objects rarely come out perfectly.
- White objects on a white background can be partly removed.
- Very small or blurry images give rough edges.
- Thin light outlines (halos) can appear on dark backgrounds. Check results on the dark backdrop before using them.
- Batch processing is not available yet.
