NIM Studio

Free · Private · Runs in your browser

Erase objects & watermarks in seconds

Brush over a watermark, an unwanted object, or a blemish — and it’s gone. It runs entirely on your device; your images never leave the browser.

How it works

Erase in three steps

No sign-up, no upload, no waiting. Everything happens in your browser.

  1. Drop your photo

    Any image with something you want gone — JPG, PNG or WebP.

  2. Brush over what to remove

    Paint across the watermark or object — it’s inpainted right in your browser.

  3. Download the clean image

    Save the cleaned-up photo — or send it straight to Compress or Convert.
