How it works
- 1
Add your photos
Drag in up to 100 JPG, PNG or WebP photos, straight from your phone or camera.
- 2
Pick your marketplaces
Tick Amazon, Etsy, Shopify or eBay. Each gets its own size, margin and background rules.
- 3
Download one ZIP
Get one folder per marketplace with files named the way you want, ready to upload.
Why sellers use it
- Private by design: photos are processed in your browser, never uploaded.
- Phone photos come out the right way up, using the rotation saved by the camera.
- Transparent PNGs get a solid background instead of turning black, or stay transparent for Shopify if you prefer.
- Small photos are never stretched, and you get a warning when one is below the recommended size.
Frequently asked questions
Is SizeMyListing free?
Yes. There is no account, no watermark and no limit on how often you use it. The site is supported by ads.
Are my photos uploaded anywhere?
No. Resizing, framing and zipping all happen inside your browser. Your photos never leave your device, which also makes it fast: there is nothing to upload or download except the final ZIP, which your browser creates locally.
Which marketplaces are supported?
Amazon, Etsy, Shopify and eBay. Tick as many as you sell on and you get one folder per marketplace in the ZIP, each sized to that marketplace's recommendations.
How many photos can I process at once?
Up to 100 photos per batch, each up to around 20 MB. Photos are processed one at a time to keep your browser responsive. For more, download the ZIP and start another batch.
Can I use iPhone HEIC photos?
Not directly. Browsers can't reliably read HEIC files, so export them as JPG first (in the Photos app, share or export as JPEG), or set Camera › Formats › Most Compatible on your iPhone so new photos are saved as JPG.
Will my photos be cropped?
Not by default. "Fit inside" keeps the whole photo and adds background around it. Choose "Fill" if you prefer the photo to cover the whole canvas, which crops the edges that don't fit the marketplace's shape.
