Remove Image Background
AI automatically detects and removes the background.
Everything is processed locally in your browser. No selects.
Consent to Load AI Model
This tool processes images safely in your browser without sending them to any server. Therefore, an AI model of about 100MB will be downloaded during the first process. We recommend using a Wi-Fi environment.
The first run downloads ~100MB AI model. Subsequent uses load from cache instantly.
About
This is an online tool that uses AI to automatically remove the background from images and export them as transparent PNGs. Because it runs a machine learning model via ONNX Runtime inside your browser, your images are never sent to a server to any server.
It can handle a wide variety of tasks including creating cutouts for e-commerce products, generating composite assets for YouTube thumbnails, and removing backgrounds for social media profile pictures.
On the first run, the tool needs to download a ~100MB AI model (it will be cached in your browser so subsequent uses will load instantly).
How to Use
Select Image
Drag and drop a JPEG, PNG, or WebP image, or click the area to select one.
Wait for AI
The AI will automatically detect and remove the background. Processing takes about 3-15 seconds depending on the image size and device.
Save PNG
Verify the transparency on the checkerboard background and save it using the "Save PNG" button.
Glossary
- Background Removal
- The process of keeping only the foreground (person or object) of an image and making the background transparent. Saving as PNG preserves this transparency through an alpha channel.
- ONNX Runtime
- An inference engine for machine learning models developed by Microsoft. It runs via Wasm (WebAssembly) or WebGPU in the browser, enabling AI processing directly on your device.
- Segmentation
- A computer vision technique that classifies pixels in an image into foreground, background, etc. Also known as "semantic segmentation".
- Alpha Channel
- An information channel representing the transparency of an image (0 = fully transparent to 255 = fully opaque). Supported by PNG and WebP formats, but not JPEG.
- WebGPU
- A modern web standard API that provides direct access to the GPU from the browser. Used to significantly accelerate AI inference. Supported in Chrome 113+.
- IndexedDB / Cache API
- Built-in client-side storage mechanisms in browsers. Used to cache the ~100MB AI model to ensure fast loading on subsequent uses.
- Foreground Extraction
- A core task in AI image processing. This tool uses a pre-trained model via the @imgly/background-removal library to extract foregrounds precisely.
FAQ
- Q.Mon image sera-t-elle envoyée à un serveur ?
- Non. Le modèle d’IA est téléchargé et exécuté dans votre navigateur et s’exécute entièrement localement. Vos données d’image ne sont jamais transmises à l’extérieur.
- Q.Combien de temps cela prend-il?
- Cela dépend de la taille de l'image et des performances de votre appareil. Généralement 3 à 15 secondes. Il est nettement plus rapide sur les appareils dotés d'un GPU et d'un navigateur prenant en charge WebGPU.
- Q.Quelle est la taille du enregistrement du modèle ?
- Il fait environ 100 Mo. Il sera stocké dans l'API Cache de votre navigateur afin qu'il se charge presque instantanément la prochaine fois que vous l'utiliserez.
- Q.Puis-je l'utiliser sur un smartphone ?
- Oui, mais le traitement des images volumineuses peut être lent en raison de contraintes de mémoire. Nous recommandons des images ne dépassant pas 2 048 px sur le bord le plus long.
- Q.Peut-il découper des arrière-plans complexes ?
- L'IA gère une grande variété d'images, mais la précision peut diminuer si les couleurs de premier plan et d'arrière-plan sont extrêmement similaires. Les images à contraste élevé fonctionnent mieux.
- Q.Quel est le format de l'image de sortie ?
- Il sera sorti au format PNG transparent. PNG est le format optimal pour conserver les données de transparence (canal alpha).
