A little help along the way

Follow these steps. Every option is explained underneath, and nothing you add leaves your device.

  1. Add your photosDrop up to 30 photos, choose them, paste one with ⌘V or Ctrl+V, or try the sample. JPEG, PNG, WebP, AVIF, HEIC, BMP, TIFF and JPEG XL all work.
  2. Wait for the model, onceThe first photo loads the model (93.92 MB) from this site. It is kept, so the next time, and offline, it starts at once.
  3. CompareDrag the handle across the picture, or use the arrow keys, to see the photo before and after.
  4. Choose what goes behindLeave it clear, pick a colour, soften the photo's own background, or choose a photo of your own. Changes show at once, without looking for the subject again.
  5. Touch it upPress Touch up to fix what the model missed: click on something to take it away or bring it back, or paint with the brush. Every click and stroke can be undone.
  6. Frame itKeep the photo's size, cut it down to the subject, or put the subject in the middle of a square, with as much room around it as you like.
  7. Download or copyDownload the picture you are looking at, copy it to paste elsewhere, or download all of them as a ZIP.
Every option explained
How the subject is found
BiRefNet, an open model made for cutting out what is in front, looks at the photo at 512 × 512. Its outline is then fitted to the photo's own edges at full size, and the colour the old background left in soft edges such as hair is taken out, so no halo of it remains.
Graphics card or processor
Where the browser can use the graphics card for this (WebGPU with 16-bit shaders), a photo takes a few seconds; otherwise the processor does it, a little more slowly. The page says which it used.
Clear, Colour, Blurred and Photo
Clear leaves the background see-through. Colour fills it with one of the swatches or any colour you choose. Blurred puts the photo's own background back, softened. Photo puts a picture of your own behind, filling the frame.
For a shop: Amazon, eBay, Shopify and Etsy
Sets the background, framing, file type and size that shop's own help pages ask for, and links to the page it came from. A file larger than a shop's size is made smaller; one smaller than it asks for is left as it is, and the panel says so, since making it larger would only blur it. Etsy shows see-through parts as black and asks for one unedited photo in each listing.
Look: shadow and outline
A soft shadow behind the subject, or one on the ground under it, and an outline of any colour around it, as a sticker has. They are worked out from the cut-out itself, and the framing makes room for them.
As taken, Around the subject and Square
As taken keeps the photo's size. Around the subject cuts it down to what is in front, with room around it as a share of the subject's size. Square puts the subject in the middle of a square, as shops and profile pictures ask for. Nothing is made larger or smaller.
PNG, WebP and JPEG
PNG is written without loss and keeps the background clear. WebP is smaller and still clear. JPEG cannot be see-through, so a clear background becomes white in it.
Touch up: Click and Brush
A click chooses the thing under it with SlimSAM, a small open model (13.15 MB, loaded the first time you touch up), and takes it away or brings it back; its edge follows the photo's. A click on something made of parts may choose one part; click again for the rest. The brush paints what to keep or take away, and with Follow edges on it holds to colours like the one under its middle, so it stops at an edge. The photo shows faintly behind, and Show the photo shows it alone.
Signatures, stamps and logos on paper
Signature and logo background remover lifts what is drawn or printed on paper by how much darker it is than the page, with no model to download: the paper's colour is read from the picture and taken out of soft strokes, and the page's grain is let go. Light, even paper and dark ink work best.
What it can get wrong
It decides what the subject is by looking, so a busy photo with several things in front, or a subject the same colour as what is behind it, can lose or keep a part it should not. Glass and smoke are hard for any such tool. Touch up fixes what it missed.
Limits and privacy
Up to 30 photos at a time, each up to 50 MB. A photo larger than 4096 pixels on its longer side (2048 on a phone) is made smaller first, and the page says so. Everything runs in your browser; photos are never uploaded, and metadata such as location is not written into the results.
