Put a product photo on a white background

Cut the subject out of any photo with AI: our server finds it in a reduced 1024 × 1024 copy, and your browser makes the cut-out from the photo itself. Download a transparent PNG, or the same cut-out on a solid colour.

How to Remove Background

  1. 1

    Add your photo

    JPG, PNG or WebP, up to 20 files at once and 30 MB each. The file itself stays on your device: to find the subject, the page sends our server only a reduced 1024 × 1024 copy of the frame, on a computer, a phone or a tablet alike.

  2. 2

    Pick transparent or a background colour

    Transparent PNG is the default. Choose white for shop listings, or any colour of your own. Edge softness and Precise edges control how the outline is cut.

  3. 3

    Press Update result and download the PNG

    Our server finds the subject in the reduced copy and returns its outline; your browser cuts it out of the photo, drops the background and gives you a PNG. Its longest side stops at 2048 pixels unless you raise Longest side under More settings, up to 4096; a smaller photo keeps its size.

What Amazon, eBay and Google ask for

Only one of the three insists on white. Amazon's product image guide for US sellers, viewed on October 21, 2026, wants the main image on “a pure white background (RGB color values: 255, 255, 255)”. It should show the product “as 85% of the image”, at 500 to 10,000 pixels on the longest side. eBay asks for at least 500 pixels on the longest side and bans added borders, text and watermarks. Google Merchant Center asks for at least 500 × 500 pixels from January 31, 2027, and advises a product filling 75 to 90 percent of the image.

White here means 255, 255, 255

The page opens with “White background” selected and “Edge softness” at 1 under “More settings”. To find the product, it sends our server a reduced 1024 × 1024 copy of the photo. The copy is deleted as soon as the outline is ready, and the outline within about two hours. On October 21, 2026, a 12-megapixel phone photo of a paper cup came back with 99.7 percent of its background at exactly 255, 255, 255. The rest was the cup's soft edge and a few faint specks, mostly 254. On a striped mug, the steam, the table's reflection and the gap in the handle turned white; the white stripes stayed.

Crop first: the product keeps its place

The cut-out keeps your framing: the cup filled 30 percent of the width and 59 percent of the height. So crop before removing the background. In Crop Image to Square, we typed a 2108-pixel square under “More settings”, so the cup's height made 85 percent of its side. This page then gave a 2048 × 2048 PNG with the cup 1,744 pixels tall, against 910 in the uncropped result. White padding added later does not help: the padded mug still spanned 37 percent of the square's width.

Size, JPG, time and batches

The longest side stops at 2048 pixels; “Longest side” under “More settings” goes up to 4096, which kept the cup at 4032 × 3024. The result is always a PNG, 2.6 MB for the 2048 × 2048 cup. PNG to JPG at its default quality of 90 made it 267 kB, the background still 255 away from the outline. Compress Image, offered under the result, kept a PNG of 101 colors, with bands on the lid. In Chrome on a Mac, each photo took 16 to 18 seconds, mostly waiting for our server. Up to 20 photos at once come back as pulsarkit-no-bg.zip; each is one of the 30 server jobs allowed per hour.

The original stays with you; our server sees only a 1024 × 1024 copy

To find the subject, the page shrinks the frame to a 1024 × 1024 copy and sends only that copy to our server over an encrypted connection; the server returns the mask. The copy is deleted as soon as the mask is ready, and the mask within about two hours. The original file is not uploaded: the cut-out, the edges, the background colour and the PNG encoding are made in this tab from the photo itself. It works the same way on a computer, a phone and a tablet. There is no account; each photo counts towards the shared hourly limit of the server tools. The result is written from raw pixels, which also drops the EXIF block: camera model, timestamp and GPS coordinates do not travel into the file you download.

Frequently asked questions

Is my photo uploaded to a server?

Only a reduced copy, not the photo. To find the subject, the page shrinks the frame to 1024 × 1024 pixels, sends that copy to our server over an encrypted connection and gets back only the mask, the outline of the subject. Your original file stays on your device: decoding, the cut-out, the edges, the background colour and the PNG encoding all happen inside this browser tab. The copy is deleted as soon as the mask is ready, and the mask within about two hours. It works this way on every device, computers included.

How long does one photo take?

In our check on October 21, 2026, in Chrome on a Mac, a photo took 16 to 18 seconds from Update result to the finished file. About 14 to 16 of those seconds were the wait for the outline from our server, and about two the cut-out itself. Nothing has to be downloaded into the browser first, so the first photo is as quick as the ones after it. The server works out masks one at a time, so when many people use the tool at once a photo can wait a little in the queue.

Why does a server find the subject, not my browser?

Because the network is heavy. Run inside a browser tab, it first has to be downloaded and then holds more than 2 GB of memory while it works: a phone closes the tab, and many computers take half a minute per photo or fail on some graphics cards. On our server the same network returns the mask in a few seconds on any device, and your browser downloads nothing. The cost is a reduced 1024 × 1024 copy of the frame travelling over the network, which is why the note under the settings says so.

Is there a limit on how many photos I can do?

Yes, one. Each photo is a request to our server and counts towards the shared hourly limit of the server tools: 30 jobs an hour. Changing the background colour or the edges of the photo you just processed reuses its mask and does not count again. There is no sign-up, no watermark and no daily quota. Twenty photos per batch is a separate limit, set by the memory of the browser tab.

How good are the edges around hair?

Good, not perfect. Individual strands against a plain, contrasting background come out convincingly; hair against a busy background of similar colour is where every tool in this category struggles, including the paid ones. Precise edges is on by default and does most of the work; it is what stops a portrait shot on white from carrying a pale rim onto a dark backdrop. Widening Edge softness hides what is left. Switch to Fast if you would rather have the seconds back than the last of the fringe.

Can I process a whole batch at once?

Yes, up to 20 files, all with the same settings, returned as a ZIP. Each photo goes to the server as its own 1024 × 1024 copy, so a batch of twenty uses twenty of the hourly server jobs. If one file cannot be read, the rest still come back and you get a note saying how many were left out.

How is this different from Transparent Background?

Transparent Background removes one colour that you point at. It is the right tool for a logo or a scan on a flat white sheet, it needs no model and it runs instantly. This tool understands what a subject is, so it works on real photographs where the background is a room, a street or a sky. Use the simple one for flat backgrounds and this one for photographs.

Which formats can I put in?

JPG, PNG and WebP. HEIC and AVIF photos need converting first, and the tool will point you at the converter with your file already loaded. Format is detected from the file's contents rather than its name, so a mislabelled file is recognised for what it really is.
