Le foto vengono caricate su un server per rimuovere lo sfondo?

No. Il modello di intelligenza artificiale (open source, licenza Apache-2.0) viene scaricato una sola volta e poi eseguito interamente sul tuo dispositivo tramite WebAssembly: l'immagine non lascia mai il browser.

Perché il primo utilizzo è più lento?

Al primo avvio lo strumento scarica il modello AI (circa 40-80 MB a seconda del browser) necessario per l'elaborazione locale. Le esecuzioni successive sono molto più rapide grazie alla cache del browser.

Con che tipo di immagini funziona meglio?

Funziona bene su persone, prodotti, animali e oggetti con contorni ben definiti. Su bordi molto sottili o trasparenti (capelli fini, vetro, fumo) il risultato può richiedere una rifinitura manuale.

In che formato viene scaricato il risultato?

Il risultato viene scaricato come PNG con sfondo trasparente, il formato necessario per preservare la trasparenza dopo la rimozione dello sfondo.

Free Online Background Remover — No Upload, 100% Local

When to use a local AI background remover

This tool removes the background from a photo using an open source AI model running entirely in your browser via WebAssembly, without sending the image to a server.

When to use it

You need to isolate a subject (person, product, animal) from a photo to use on a transparent or different background.
You want to prepare product photos for an e-commerce store without paying an editing service for every image.
You'd rather not upload your photos to external servers, for example for privacy or confidentiality reasons.

When NOT to use it

You need very precise manual cropping on complex edges (fine hair, transparent objects like glass): an editor with manual selection offers more control.
You need to process hundreds of images in a single batch: since processing is local and sequential, a dedicated server-side service is faster for large volumes.

Alternatives

Photoshop or GIMP with manual selection/masks for maximum control over complex edges.
Specialized cloud services (e.g. remove.bg) for high-volume batch processing, at the cost of uploading images to an external server.

Common mistakes

Expecting perfect results on subjects with very fine or transparent edges (e.g. hair in the wind, glass, smoke): general-purpose AI works best on sharp outlines.
Not accounting for the fact that the first use downloads a 40-80 MB AI model: on slow connections, the first run can take a few extra seconds.
Saving the result as JPG instead of PNG, losing the transparency of the removed background.

Frequently asked questions about background removal

No. The AI model (open source, Apache-2.0 license) is downloaded once and then runs entirely on your device via WebAssembly: the image never leaves the browser.

On first launch, the tool downloads the AI model (about 40-80 MB depending on the browser) needed for local processing. Subsequent runs are much faster thanks to browser caching.

It works well on people, products, animals, and objects with well-defined outlines. On very fine or transparent edges (fine hair, glass, smoke) the result may need manual touch-up.

The result is downloaded as a PNG with a transparent background, the format needed to preserve transparency after removing the background.
