Bulk image resizer

Most online resizers handle one image at a time and give you a generic size. SelfShot is built around the batch. Drop forty photos, pick a marketplace, and every image is squared, sized, padded to white, and compressed toward that preset's file-size cap in one pass. You download a single ZIP with correctly named files.

The filenames tell you what each file is: the original name, the marketplace, and the dimensions, so a folder of exports stays organized even with dozens of photos.

If you sell the same item on more than one site, select the marketplaces and SelfShot runs every photo through each one. The free tool covers up to two marketplaces per batch. Unlimited cross-listing is the optional $9 one-time Pro unlock. It shows you the math up front, for example forty photos times two marketplaces equals eighty images, and groups the output into one folder per marketplace inside the ZIP.

You can also apply another marketplace later without re-importing. SelfShot keeps your originals in memory, so adding eBay after you have already done Etsy just adds the eBay folder to your downloads.

Nothing is uploaded. Decoding, resizing, padding, compression, and the final ZIP all happen on your own device, which is why there is no per-image limit and no waiting on a server. It also means the tool is free and your photos stay private.

iPhone HEIC files are read and rotated upright automatically, so a mixed batch of phone and camera photos all come out correctly oriented and sized.
