Product photo editor - white background photos for Allegro, OLX, Vinted and online shops

Seller Studio puts the steps you would otherwise repeat for every photo into one process: background removal, centring the product, resizing, compression and adding a logo. The settings apply to the whole set, so every photo gets the same background, margin and size. Before you download, Studio shows which photos may not meet the requirements of the platform you picked.

For one photo, the separate tools are enough: remove background, resize image, image compressor, add a watermark and HEIC to JPG. Studio uses the same accurate AI model as the "Precise" mode of the background remover, and adds marketplace profiles, a technical check and export of the whole set.

A profile sets the size, aspect ratio, format, background, margin and whether you can add a logo. The requirements in the table come from the platforms' published help pages (as of October 2026). Where a platform publishes no value, the setting is our default and you can change it. The settings follow the requirements the platform has published, but that does not guarantee the platform will accept every photo. Allegro and OLX are Polish marketplaces, and their profiles follow the Polish help pages. Other countries may differ.

The Online shop size also fits the recommendations of WooCommerce (at least 800×800 px) and Shoper (about 1000 px on the long side). For platforms without a profile, such as eBay, Etsy or Amazon, choose "Custom" and set the size from their help pages.

Photo 1, the listing thumbnail, needs a plain white background (RGB 255, 255, 255) and no frames. It cannot contain text, icons, a shop logo, the seller name or a watermark. The long side must be at least 500 px. One Allegro help page gives 400 px for thumbnails, so the profile warns below 500 px.

Exceptions depend on the category. In fashion categories the background can be white or light grey, and the garment or model should fill about 80% of the frame, uncropped and seen from the front. That is what the Allegro Fashion profile does. Some other categories have their own exceptions to the white background, for example furniture, plants and motoring, and used items on a personal account. Check your category in Allegro help. In the gallery, from photo 2 on, the background can be anything, but a shop logo and shop name are still banned. A manufacturer logo visible on the product itself is allowed.

Studio checks the background colour at the edge of the finished photo. JPG can store white as 254, so it treats channel values of 250 and above as white.

OLX usually accepts up to 8 photos per listing, up to 12 in some categories and up to 16 for accommodation. Each photo can be up to 5 MB and 5000×5000 px, as JPG, JPEG or PNG. OLX help bans photos taken from the internet, manufacturer photos and contact details on the photo. It recommends a light, plain background and the item in the centre without a lot of empty space. OLX operates in several countries, and this profile follows the rules of OLX Poland.

The OLX profile saves JPG files at 1600×1200 px. If a file would go over the limit, "Fit within" lowers the quality only as much as needed. We count the limit cautiously as 5,000,000 bytes. The 4:3 ratio and the white background are our settings, because OLX help mentions a "4:3 format" without explaining it. OLX does not regulate logos or watermarks, but the profile keeps them off by default.

The Vinted Catalogue Rules (UK version) say that no image editing is allowed. Removing a background is editing, so the Vinted profile keeps the original background by default and shows a warning if you turn background removal on. Rules differ between countries and change over time, so check them for your account.

Vinted help recommends a neutral background, daylight, no filters and showing any flaws. The first photo should show the whole item, with no collages. Vinted publishes no size, file weight or format requirements, so 1200×1600 px (3:4) and JPG are our settings. The profile crops the photo to 3:4 and resizes it, but does not change the background. When Studio recognises the product, it places the crop so the whole product is inside, and if the product does not fit, it keeps the whole photo and fills the edges with the background colour. We do not know whether Vinted counts plain cropping to a ratio as editing. If you would rather not crop, choose "Same as photo" under "More settings".

Without AI, Studio compares the colours at the photo edges with the rest of the frame. When the background is plain (a sheet of paper, a wall, a table top), including a soft change in brightness or darker corners, Studio outlines everything that differs from it and centres that area with the margin you chose. It replaces the background connected to the photo edges with the one you pick, such as white, with a soft transition along the product edges. A shadow under the product is darker than the background, so it stays. Background enclosed by the product, such as inside a mug handle, keeps its colour from the photo. For a PNG with transparency, Studio uses the transparency channel. With AI background removal on, a model cuts out the product itself, usually without the shadow, and Studio centres it on the background you pick.

Without AI, the background stays as it is in the photo when:

• the background is busy, for example a patterned tablecloth or several objects in the frame. Studio shows a "Busy background" note, does not crop the photo and places the whole photo on the chosen background. Turn on AI background removal.
• the product fills almost the whole frame. There is nothing to crop, so Studio keeps the whole photo.
• a white product sits on a white background and the colours do not differ. Studio may not find the product ("No product found" note) or may merge its light parts with the background. AI helps here too.

Other limits:

• A strong shadow or reflection counts as part of the product, so the product ends up smaller or slightly off centre.
• On a transparent background without AI, the shadow stays as a light patch. Studio shows a note when this can happen.
• The AI model may cut thin parts, glass and shiny surfaces less accurately. The mask is made at up to 1024 px and scaled up to the photo. Check the result in the before and after view.

If one photo came out worse, fix it under "This photo", for example by turning AI on for that photo only.

• Put the product on a plain, light surface, such as a sheet of paper or a wall. The fewer patterns, the more reliably Studio finds the edges of the product without AI.
• Leave some space around the product. A product touching the photo edge may be cut off, and Studio flags such a photo.
• Shoot in daylight with the product in focus. Blurred edges give a less accurate cut-out.
• Get close but keep the whole product in the frame. If the product fills only a small part of the source photo, Studio has to enlarge it a lot and warns that the result may look soft.
• HEIC photos from an iPhone can be added without converting them first.

Your photos are not uploaded to a server. Loading, background removal, framing, compression and building the ZIP all happen in your browser. The only things downloaded from the internet are the AI model for background removal and the files needed to run it. Your browser fetches them the first time you turn on background removal (about 100 MB; you see the size before the download and can cancel it), then keeps the model in its cache until you clear the browser data. If you never use AI background removal, the model is never downloaded.

The output files carry no EXIF metadata, including GPS location, because every photo is saved again from scratch. Studio shows how many photos had a location stored.

The check covers technical parameters: size, file weight, format, number of photos, background colour, the position of the product relative to the edges, how much of the frame the product fills (Allegro Fashion) and whether a logo is on. It does not guarantee that a platform will accept the photo. Studio does not check text, logos or faces in the photo and does not know whether the photo is yours. Platforms change their rules, and some requirements depend on the category, so look at the platform's help before you list a product. For Allegro, the profile warns above 16 photos, although motoring and real estate listings allow 40.

Allegro help describes labelling for images generated or substantially changed by AI. It does not say whether that covers removing a background and replacing it with a plain one, so we do not decide that either. If you use AI to change a photo, check the Allegro rules on labelling.

Background removal speed depends on your device. A graphics card (WebGPU) speeds it up, and without one the model runs on the processor and is slower. Photos larger than 4096 px on the long side are scaled down so the browser does not run out of memory.
