PNG or JPG? Keep transparent product photos ready for export
Choose an export format deliberately, understand when a white background is added, and check a sample before processing a product photo collection.
Decide whether the background should stay transparent
Before choosing a format, decide how the exported picture will be used. A transparent product cutout can be useful when another editor will place it on a colored background. A white-background working copy may be more convenient when you want a consistent rectangular picture. Keep the original file so you can make either version later.
The 0UB batch image studio converts and resizes existing images. It does not remove a photographed background or create a transparent cutout. If the source already has transparency, PNG is the appropriate export choice when you need to retain it. Choosing PNG alone does not make an opaque background disappear.
Match the resize mode to your background choice
Select one representative image and choose your target width and height. Fit inside keeps the picture within those bounds without enlarging it, so the resulting dimensions can be smaller than the box. Center crop fills the requested frame and may trim the product edges. Inspect the shape and any fine details before accepting a crop.
White padding creates an exact-size canvas and deliberately adds a white background. That happens even when you export a PNG. If your goal is to keep transparent areas, avoid white padding and inspect a PNG made with a suitable alternative resize mode. Do not assume the file extension overrides the selected background treatment.
Compare one PNG with one JPG
Export a PNG first and open the downloaded file in the editor or destination where you intend to use it. Check the product outline and the surrounding area. A viewer may display its own background behind transparency, so its white appearance alone does not prove that the file has an opaque white background.
For a white-background copy, export JPG. The studio fills transparent regions with white for JPG output. The quality slider affects JPG and WebP exports; it does not control PNG quality. Compare the downloaded results at their intended viewing size rather than relying only on the filename or preview.
Keep originals and review the collection
Store source cutouts separately from the converted copies. Use a clear export prefix to distinguish a white-background collection from transparent working files. Check labels, fine edges and product placement in a sample before applying the settings to the rest of your images.
Single-image processing is free; multi-image conversion and ZIP downloads require a Pro pass. File processing stays in your browser, but browser memory and the documented file limits still apply. If a batch contains failures, review the reported results and keep the originals available for another attempt. Conversion does not guarantee acceptance by a marketplace or social platform.
