Why square listing photos?
Most resale apps show your photos as square thumbnails in search results and feeds. Upload a tall phone photo and the app crops it for you, often cutting off the top of a dress, the collar of a shirt or the toe of a shoe. Making photos square yourself means you decide what buyers see.
"Fit whole photo" adds plain white (or black) edges instead of cropping, so the whole item is always visible. "Fill frame" crops the edges instead, which works well when the item is centered with space around it.
Best photo sizes for each marketplace
| Platform | Shape shown | Suggested size |
|---|---|---|
| eBay | Square thumbnails | 1:1, 1600–2400 px (500 px minimum; bigger enables zoom) |
| Poshmark | Square | 1:1, 1600 px |
| Depop | Square | 1:1, 1600 px |
| Mercari | Square | 1:1, 1600 px |
| Vinted | Portrait thumbnails | 3:4 or 1:1, 1600 px |
| Etsy | Varies (often 4:3 in search) | 1:1 or 4:5, 2000 px |
Marketplaces change their layouts from time to time; square photos at 1600 px are a safe default almost everywhere.

FAQ
Will resizing reduce quality?
Photos are resized with high-quality smoothing and saved as JPG. At 1600 px and "Balanced" quality, they look sharp on every marketplace while being much smaller than the originals.
Are my photos uploaded anywhere?
No. All resizing happens in your browser. Nothing leaves your device.
Does it work with iPhone HEIC photos?
Safari on iPhone and Mac reads HEIC photos fine. Other browsers may not, so if a photo shows an error, share it as JPG ("Most Compatible" in your camera settings) and try again.
Is my photo rotated correctly?
Yes. The tool follows the rotation saved by your camera, so portrait photos stay upright.
