Marketplace rules on the main image
A shop’s product photos get copied: onto other listings, into resellers’ catalogues, into adverts you did not pay for. A mark with your shop name on it is the simplest answer. But the photo that matters most — the main image a marketplace shows in search — is usually the one you are not allowed to mark. Amazon’s policy, quoted on its own seller forums, rules out text, logos and watermarks on the main image. Rules on other marketplaces are not checked here; read your marketplace’s current rule.
So this mode keeps file 1 clean. Name the main photo so it sorts first, drop the whole folder, and the run copies that file through untouched while every other photo gets the mark.
White backgrounds and invisible marks
Studio product shots are mostly white, and a white mark on white is no mark at all. The ink here starts on Auto: before the mark goes on, the pixels where it will land are read and the mark is drawn black or white, whichever has more contrast against them. On a folder run the ink rule measures every file after marking and writes the achieved contrast on its line.
| Auto ink | Black or white per photo, measured from the pixels under the mark. |
|---|---|
| Ink rule (folders) | Raises the ink on a file only as far as it needs to reach the contrast floor you choose, and never past the ceiling. |
| Plate | A soft rounded plate behind the words, for photos where neither black nor white reads on its own. |
Logo or handle
A handle such as @yourshop is quick and survives being small. A logo is more recognisable and works best as a transparent PNG or an SVG; a JPG logo on a white box can have the box knocked out by colour on this page. Either way the size is a share of each photo’s width, so a folder of 1,000-pixel phone shots and 4,000-pixel camera files gets the same proportion everywhere. See the logo mode for the clean-ups.
Keeping file 1 clean
The clean file is copied byte for byte, so it is exactly the file you dropped — including any camera data or location it carried. The marked files carry none of that unless you ask under Export. Everything happens on this device; the folder is read here and written back as a ZIP or into a folder you pick.
- Only the first file in name order can be kept clean in a run. Mark a different set by queueing it separately.
- Whether a marketplace accepts marks on its other images is that marketplace's rule, not something this page can check.
Product photo watermark questions
Can I watermark my main Amazon image?
Amazon's product image policy, as quoted on Amazon's own seller forums, says the main image must not include text, logos, borders, colour blocks, watermarks or other graphics. So this mode can keep file 1 clean: drop the folder, and the first picture in name order is copied through unmarked while the rest get your mark. Rules on other marketplaces differ — check the current rule for yours before you mark a main image.
Will a white watermark show on a white background?
No, and that is the commonest failure with product shots. Here the ink starts on Auto: for every photo, the pixels under the mark are measured and the mark is drawn black or white, whichever reads. On a folder run the ink rule goes further and records the contrast the mark actually reached on each file, so a faint one is named in the list rather than hidden in the ZIP.
Can I keep one photo clean?
Yes — “Keep file 1 clean” under Run, which this mode switches on for you. The first file in name order is copied into the ZIP byte for byte, unmarked, and its line in the list says “kept clean” so nobody wonders whether it was missed. Rename the photo you want as the main image so it sorts first (for example 00-main.jpg).
Logo or shop name?
Either. The mode starts with a handle in a clean geometric face; switch to Logo to open your logo file — PNG, SVG or a JPG with a white box, which can be knocked out — and it is drawn at the right size on every photo, whatever its pixel dimensions.
