Make the background white behind your listing photos
Backdrop lifted to white at the standard setting.
Only the connected background is touched, and it is blended into the item rather than cut around it. Everything the fill refuses is left byte for byte — this is not a cut-out, so nothing is redrawn or invented.

Vinted does not allow edited photos
Vinted
Vinted's Catalogue Rules state that no image editing is allowed. Resizing and cropping to fit the frame is ordinary preparation, but do not whiten backgrounds or retouch out marks — Vinted asks you to show wear.
Vinted — Catalogue Ruleschecked 2026-08-20
Everywhere else, tidying a plain backdrop is ordinary listing preparation. What no marketplace permits is editing that hides the condition of the item — so do not reach for this, or anything else, to make a mark, a stain or a worn patch go away. Photograph the flaw and say what it is; it is also what stops a return.
This is arithmetic, not a cutout
There are two ways to change the background of a photograph. One is to work out what the item is — a model trained on millions of pictures, drawing a mask around the subject — and then replace everything outside it. The other is to notice that the background of a listing photo is usually a large, flat, pale area connected to the edges of the frame, and to fill outward from those edges for exactly as long as the pixels keep looking like the pixels you started from.
This tool does the second. It is narrower, it will refuse photos the first would manage, and in exchange it is completely predictable: it never invents detail, never guesses at an outline, and never touches a pixel it could not reach by walking there from the edge of your photo.
1 · Measure the backdrop
A band 1% of the short edge deep — about 15px on a 1500px photo — is sampled all the way around the frame, and its median brightness becomes "the background". A median rather than an average, so a dark corner or a stray thumb in the shot does not drag the figure it is meant to be measuring. That number is printed on every card, out of 255, and it is the one measurement worth checking against your own eyes.
2 · Spread inward, only through connected pixels
The fill starts from every accepted pixel in that band and spreads to its neighbours, one step at a time. Because it can only travel through pixels it has already accepted, anything enclosed by your item is safe — the pale patch inside a handbag handle, the gap between a shoe and its strap. A tool that simply whitened every light pixel in the frame would take those too, along with the label on your garment.
3 · Three separate reasons to stop
A pixel is only taken if it passes all three. It has to be bright enough — within the tolerance of your chosen setting, and never darker than 128 out of 255 whatever that setting says. It has to be roughly as neutral in colour as the backdrop was, which is what stops the fill wandering into a saturated red jacket that happens to be bright. And the picture must not be changing steeply there, which is what an outline is: the fill stops at edges even when the pixel beyond one would otherwise have qualified.
4 · Blend the join, do not cut it
The whitened area is composited over the original through a ramp about 8px wide on a 2000px photo, so the boundary is a soft falloff rather than a line. This is the single biggest difference between a photo that reads as tidied and one that reads as faked: a hard one-pixel outline around a garment is what makes a buyer think they are looking at a stock image. Everything the fill refused is left byte for byte.
Three settings, and all three are about the shadow
The only thing the setting changes is how far below the measured backdrop a pixel may sit and still count as background. Turn it up and you take more of the backdrop; you also take the shadow under the item, and an item with no shadow looks like it is floating on a blank page. That is the whole trade, which is why there is no slider — a number between 0 and 100 cannot be labelled with the thing you actually care about.
Light
15 levels below the backdrop
Lifts a background that is already nearly white. Keeps every shadow.
Standard
33 levels below the backdrop
Cleans up a grey or beige backdrop, and keeps the shadow under the item.
Strong
61 levels below the backdrop
For a dim or patchy backdrop. Will take soft shadows with it.
Those figures are the same constants the tool runs on, restated out of 255 so they line up with the backdrop measurement printed on each card. A backdrop measured at 236 processed at the standard setting will take everything down to about 203 — which is why the number on the card is worth a glance before you decide the tool is wrong.
Changing the setting recomputes every preview immediately, on your own photos, with no download and no round trip. That is the intended way to use this: look, adjust, look again.
What this cannot do
- Cut your item out. There is no mask and no transparency — the background becomes white, it does not become nothing. Fine edges are exactly where this approach has least to offer: hair, lace, mesh, tulle and fur all need a model that understands what it is looking at. If you need the item on a coloured card, you need a different kind of tool than this one.
- Separate a pale item from a pale backdrop. A cream jumper on a white sheet gives the fill nothing to stop at, and it will walk through the garment. The preview shows you that happening before you download, and the gentler settings help — but if the lightest one still takes the item, no setting will fix it. A mid-grey sheet costs a few pounds and solves it permanently.
- Work on a patterned background. A duvet print, a wood floor, a rug, a hedge: the fill refuses all of them, and refusing is the right answer. A flood fill forced through a pattern produces torn white blotches, which looks considerably worse to a buyer than the pattern did.
- Fix a photo with no room around the item. The fill has to start at the edges of the frame, so an item cropped tight to all four sides leaves nothing to start from. Re-shoot with a hand's width of space around it, or use the resizer to pad the photo out to the ratio you need first — its fit mode pads with white, and padding is not editing.
- Improve a badly lit photo. This lifts a backdrop; it does not add light. A backdrop darker than mid-grey is refused outright, because lifting it to white would drag the item's own shadows and dark fabric up with it and leave the colour of everything you are selling wrong. Move nearer a window. It is the highest-value thing any seller can do to their photos and it is free.
- Substitute for accurate colour. Several of these marketplaces ask for photos that show the item's true colour, and a buyer who receives something a shade off what they saw opens a case. Whitening the backdrop does not touch the item, which is the point — but if the whole photo has a colour cast, that cast is still in your item too, and the fix is the light rather than a tool.
Files come back as JPEG at their original dimensions. If you also need to hit a size limit or a platform's exact frame, run this first and then the compressor or the resizer — a flat white backdrop is the easiest thing a JPEG encoder ever has to store, so a whitened photo compresses further than the one it came from.
Common questions
- How do I make the background of a photo white?
- Drop the photo in and the plain area around your item is lifted to pure white, blended into the item's edges rather than cut around them. It works by brightness: the tool measures what the backdrop actually is at the edges of your frame, then spreads outward from there taking everything that is close enough to that measurement. A white or light grey sheet, a pale wall, a bit of white card — those all work. A patterned rug does not, and the card will tell you so rather than producing something odd.
- Is editing my listing photos against the rules?
- It depends on the marketplace, and one of the six on this site says no outright. Vinted requires photos to represent the item as it is and states that no image editing is allowed, so cleaning up a backdrop there is a rule you would be breaking rather than a tip. Everywhere else, removing distraction from behind an item is ordinary listing preparation and some platforms explicitly recommend a plain background. What no marketplace permits is editing that hides the condition of the item — do not use this, or anything else, to make a mark or a stain disappear.
- Why did my item turn white along with the background?
- Because the tool works by brightness, and your item is about as bright as the backdrop behind it. A cream jumper on a white sheet is the classic case: there is no brightness boundary for the fill to stop at, so it walks straight through the garment. The card shows you this before you download anything, and offers a gentler setting. If even the gentlest one takes the item, that photo needs a darker backdrop rather than a different setting — this is a limit of the method, not a bug to be tuned around.
- Why did nothing happen to my photo?
- One of two reasons, and the card says which. Either the item runs right to the edges of the frame, in which case there is no border for the fill to start from and the fix is to re-shoot with space around the item or to pad it out with the resizer. Or the backdrop is not plain — a patterned duvet, wood grain, a busy carpet — and the tool refuses it deliberately, because a flood fill through a pattern produces a torn, blotchy mess rather than a clean backdrop.
- Does this give me a transparent PNG or a proper cutout?
- No, and it is worth being clear about the difference. This flattens the background to white; it does not separate your item from it. There is no alpha channel, no mask, and no edge detection around hair, lace, mesh or anything else fine. If you need a genuine cutout — to drop the item onto a coloured card, or to composite it into a template — this is not the tool, and the honest answer is that browser-side background removal that handles those edges well needs a machine-learning model rather than arithmetic.
- Should I keep the shadow under my item?
- Usually yes. A shadow is what stops a flat-lay looking like the item has been pasted onto a blank page, and buyers read that pasted look as a stock photo rather than a real garment on a real floor. That is why each setting is labelled by what it does to the shadow rather than by a number: the light setting keeps every shadow, and the strong one will take soft ones with it. If in doubt, use less.
- Do I need a white background to sell?
- No marketplace on this site requires one. What several of them do ask for is a plain, uncluttered background and accurate colour, which is a lower bar and a more sensible one — a clean grey sheet in good light beats a badly whitened photo every time. The reason white is worth reaching for is consistency: a grid of listings that all share the same backdrop reads as a shop rather than a pile of snapshots, and that is the actual effect being bought here.
- Are my photos uploaded to a server?
- No. Every pixel is examined inside this browser tab, by the same code that draws the live preview beside your photo — that preview is the real algorithm running on a smaller copy, not a mock-up of it. There is no server to send a photo to. Open your browser's network inspector and whiten a batch if you would rather check than take our word for it.
