If you sell online, you rarely need to remove the background from one photo. You need to remove the background from multiple images at once — a new collection, a supplier's folder, a whole season — and have every photo come back looking like it belongs in the same catalog. This guide shows how to do that in one run, what to decide before you start, and the marketplace specs worth building into your settings.
The short answer
To remove the background from multiple images at once:
- Collect the photos in one place. JPG, PNG, WebP and HEIC phone photos can be mixed.
- Decide the result once: background (white, a color or transparent), margins, where the product sits, output size and file format.
- Run the whole batch with those settings, so every photo is treated the same way.
- Spot-check the results in a grid rather than opening files one by one.
- Save the settings as a preset, so the next batch matches this one.
The rest of this guide explains each step, and why step 2 matters more than the background removal itself.
Why removing the background is only half the job
Most tools that handle several images at once do one thing: they cut the product out. What you get back is a set of transparent files where every product is a different size, sits in a different spot and has a different amount of empty space around it. Put those on a category page and the grid looks uneven, even though every cut-out is clean.
A listing photo needs more than a clean edge. It needs the same background, the same margins and the same position as the photo next to it, at the exact pixel size the marketplace asks for. If those steps happen in a second or third tool, the batch has to be exported, re-imported and checked again each time. Deciding them up front, and applying them in the same run as the background removal, is what turns a folder of cut-outs into a finished catalog.
Decide the result before you upload
Background: white, a brand color or transparent
- Pure white is the safe default for marketplace main images. Several marketplaces require it outright.
- A brand color works well for your own store and for campaign pages, where a consistent tint makes a range feel designed.
- Transparent PNG is for design work: banners, ads and layouts where someone will place the product on something else later.
If you sell on more than one channel, you will usually need more than one of these. That is fine, as long as each channel gets its own saved setting rather than a manual export every time.
Margins and position
This is the setting most batches get wrong. A tall bottle and a flat wallet photographed the same way will end up at very different sizes in the frame. The fix is to place every product inside the same safe area: the product is scaled to fit the area and centered in it, so the empty space around each item is consistent across the whole range.
A useful way to set the margin is to work backwards from the marketplace rule. If a marketplace wants the product to fill about 85% of the image, then on a 2,000 × 2,000 px square the product's longest side should be around 1,700 px, which leaves roughly 150 px of margin on each side.
Output size and file format
- Size: set the exact width and height each channel asks for, instead of exporting at whatever size the original happened to be.
- JPG or WebP for listings, where file size and loading speed matter.
- PNG when you need transparency or will edit the image again.
- A maximum file size if a channel rejects heavy uploads, so the export is compressed to fit.
Marketplace image specs worth building into your settings
The figures below come from each platform's own seller documentation. Marketplaces update these rules, so check the linked page before a large run.
| Channel | Background | Size guidance | Watch out for |
|---|---|---|---|
| Amazon (main image) | Pure white, RGB 255, 255, 255 | At least 1,000 px on the longest side to enable zoom. The product should fill about 85% of the frame. | No text, logos or watermarks on the main image. Switch your logo off for this preset. |
| Shopify | Your choice. Keep it the same across the store. | 2,048 × 2,048 px usually displays best for square images. Maximum 5,000 × 5,000 px (25 megapixels). | Files must be under 20 MB. PNG and JPEG are the recommended formats. |
| Etsy | Your choice. Plain backgrounds keep thumbnails readable. | At least 2,000 px on the shortest side is recommended. | Thumbnails are cropped, so keep the product well inside the frame. |
One catalog can serve all three: save one preset per channel with its own background, margin and size, and run the same source photos through each.
Step by step: remove the background from multiple images in one run
Here is how the workflow looks in Shoupapp's bulk background remover. The same principles apply whatever you use.
- Upload the photos. Drag in a folder or pick photos already in your library. Up to 1,500 photos can go into a single run, and mixed formats and sizes are fine.
- Choose the background. White, any color, or transparent.
- Set the layout. Switch on automatic positioning so every product lands in the same safe area, then set the margin, or a crop or extra padding if a channel needs it.
- Add the finishing steps you need. A natural shadow under the product, a light enhancement, your logo, and the exact output size and format. These run in the same pass, and the photo still costs one credit however many of them you switch on.
- Start the run and leave it. Large batches run in the background, so you can close the tab and keep working. Results appear in your library next to the originals, which are never overwritten.
- Download or keep it running. Take the whole batch in one download, or save the settings as a preset for the next one.
Prepare photos so the cut-out stays clean
Background removal is only as good as the edge it can see. A few habits at the shoot make a large batch much cleaner:
- Shoot on a plain background that contrasts with the product. A dark product on a light backdrop, or the reverse, gives a clear edge to follow.
- Light the background evenly. Hard shadows falling onto the backdrop can be mistaken for part of the product.
- Take extra care with fine edges. Hair, fur, fringes and thin straps are where cut-outs most often lose detail. More contrast and sharper focus there pay off.
- Keep the whole product in frame. A cropped corner cannot be recovered later, and automatic positioning will center what is there.
- Shoot the range the same way. The same distance, angle and lens across a collection makes the finished grid look like one shoot.
After the background is gone: shadow, position and size
A product on flat white can look pasted on. A soft shadow underneath puts it back on the ground, and it is one of the details that separates an edited catalog from a photographed one. When the shadow is drawn from the product's own outline, it follows the real shape of a shoe or a bottle instead of a generic oval.
Shoupapp offers four shadow styles in the same run as the background removal: Contact, Soft, Floating and Studio. For marketplace main images, a tight Contact shadow on pure white is the conservative choice. The product shadow guide covers which style suits which listing.
Positioning and resizing come last, once the product is cut out and the shadow is in place, so the margin is measured around the finished product.
Check a large batch without opening every file
With hundreds of photos, reviewing each file one by one is not realistic. A quicker routine:
- Scan the grid first. Uneven positioning, a missed background or a wrong size stands out immediately when the results sit side by side.
- Zoom in on the hard cases. Check products with hair, fur, glass, mesh or thin parts, and leave the simple boxes and bottles.
- Check one file per channel against that channel's spec: pixel size, background color and file size.
- Re-run what needs it. A photo that fails to process is refunded automatically, so there is no need to track it down or ask for the credit back.
Make it repeatable: presets and schedules
The first batch is where you decide the settings. Every batch after that should reuse them. Save each channel's settings as a preset, and next season's photos come out identical to this season's, even if someone else runs them.
If new photos arrive regularly, you can go one step further. With automation, photos that land in your library are processed on their own with the preset you chose, and you get an email when the run is finished. Agencies use the same approach per client: one preset for each client's spec, applied to every new shoot.
Frequently asked questions
Can I remove the background from multiple images for free?
Free tools usually cap a batch at a small number of files and stop at the cut-out. For a real catalog, what matters more is whether margins, position, size and format are applied in the same run. Otherwise the time saved on the cut-out is spent again on resizing and aligning. You can see what a run costs on the pricing page.
How many images can I process at once?
In Shoupapp, up to 1,500 photos per run, as far as your credits cover. Larger catalogs can be split into several runs with the same preset, so the results still match.
Which format should I export in?
JPG or WebP for marketplace listings, where small files load faster, and PNG when you need a transparent background for design work.
Will my original photos be changed?
No. Every result is saved as a new file next to the original, and the original stays exactly as you uploaded it.
Can I add my logo to every photo?
Yes. Upload the logo once and choose where it sits, and it is placed on every photo in the run. Leave it off for marketplace main images that forbid logos, such as Amazon's.
Start with one preset
Pick your most important channel, write down its background, margin and size, and run one batch with those settings. Once the result looks right, save it as a preset and every batch after that is one upload. See how the bulk background remover works.
