Marketplace-ready images in one pass. Nothing uploads — your photos stay on this device.
Marketplace-ready images in one pass. Nothing uploads — your photos stay on this device.
Every marketplace has its own idea of a correct product image, and they disagree with each other. A listing photo that looks right on one platform gets rejected, letterboxed or cropped on the next. Sellers usually discover this one upload at a time, which is the slowest possible way to find out.
SellaFit resizes the whole shoot in one pass against the target marketplace's spec, then renames the files so they arrive in the right order. It runs entirely in the browser — the photos are read from your disk, resized locally, and handed back as a download. Nothing is uploaded, which also means a hundred-image batch is not a hundred-image upload.
JPG, PNG and WebP go in; marketplace-ready JPG (or PNG) comes out.
Batches of up to five are free. A one-time purchase removes the limit and adds saved presets and saved rename patterns for shoots you repeat.
No. Everything runs on your own device — useful when the shoot is for a product that has not launched yet.
Downsizing to a marketplace's own target dimensions is what the platform would do to your image anyway; doing it locally means you control the result rather than accepting theirs.
