Is this different from the main batch optimizer?
It uses the same tool and the same queue flow. The difference is the eBay-oriented copy and the practical marketplace profile that loads first.
Can I change the output settings after loading the page?
Yes. The default profile is only a starting point. You can still change the normal batch controls inside the tool.
Does the pack stay local?
Yes. Queue processing and ZIP export stay in the browser, and the saved files are rebuilt through canvas so common metadata is stripped on save.
What size should eBay photos be?
At least 500 pixels on the longest side, with 1600 recommended so buyers can zoom. The square profile here exports 1600 x 1600.
Can I add a watermark to my eBay photos in bulk?
Only an ownership mark. eBay's picture policy allows a watermark that identifies you as the photo's owner and prohibits watermarks carrying promotional content, a website, a price or contact information. Added borders and text are also prohibited.
How many photos can I process at once?
Up to 100 per queue at up to 15 MB each, exported as a zip. eBay allows 24 free photos per listing.
Does fit framing add a border eBay would object to?
Fit scales the photo onto the canvas and fills the remaining space with the background colour, which is a canvas, not a decorative border. If you want to avoid the question entirely, use fill framing so the photo reaches every edge.
Does the batch run on a server?
No. Every file is decoded and re-encoded on a canvas in your browser, and the zip is built locally.
