Hi everyone, I'm Harry, and I built SizeSpec.

Every marketplace wants product photos in its own size and shape. Etsy asks for 2000 px and now prefers landscape, eBay bans added borders, Amazon wants pure white, Shopify suggests 2048 px and files near 200 KB. Most sellers resize one photo at a time, or guess.

SizeSpec makes it one step: pick the marketplace, drop your photos, download one ZIP with every image sized, cropped or fitted on white, and resized and compressed using marketplace-specific presets. Every preset links the marketplace's own help page and the date it was checked.

  • It runs in your browser. Resizing, cropping and compression happen in your browser. Those photos aren’t uploaded. Optional AI photo features use external processing and are sold separately

  • Free: 1 pack a month (up to 5 photos), no card, plus free JPG, PNG and WebP converters.

  • Premium removes the monthly limit, with packs of up to 200 photos.

  • New: AI photos, if you don't have a product shot yet.

I'd love your honest feedback: which marketplace or size is missing, and where did the studio feel slow or confusing?
