Will converted images keep their file names so I can match them to product SKUs?

The exact rule

The Image format converter removes only the last extension from a name, meaning the final dot and what follows it, then adds the new format's extension in lower case. Everything before that stays character for character, including capitals, spaces, hyphens and inner dots.

A tidy routine for a store catalogue

1. Name each image by product code before converting, adding a short tag for multiple shots, such as sku-3310-front and sku-3310-back.
2. Add the batch to the tool and choose the target format.
3. Download all to get converted-images.zip with the same names.
4. Upload the images, or link them to products in your product sheet, by name.

Three cases worth a look

First: two files with the same name in different formats, such as sku-2201.png and sku-2201.webp, converted together to JPEG. Both become sku-2201.jpg, so inside the ZIP the tool renames the second to sku-2201 (2).jpg so neither overwrites the other. Check for this before uploading, because the second name will not match a product code.

Second: a name with two extensions, such as IMG_0412.HEIC.webp. The tool removes only the last one, giving IMG_0412.HEIC.jpg. Technically fine but confusing, so clean it up before converting.

Third: a file with nothing before the extension, such as one called just .png. Nothing is left once the extension goes, so the tool names it file, and it comes out as, for example, file.webp.

Images left unconverted

If some images were already in the target format, you will not find them in the ZIP, because it only holds what was converted. Their original names never changed, so copy them into the same folder to complete the set. And if you download a single image with its own button, your browser may add a number to the name when a file with that name is already in Downloads; that comes from the browser, not the tool.
