When an Etsy upload stalls, reduce waste before detail.

Large files, unsupported formats, weak connections, and malformed metadata can look like the same upload failure.

Check simple causes first

1. Confirm the file opens normally.
2. Use a supported format such as JPG or PNG.
3. Try one image instead of a gallery.
4. Test another network or browser.
5. Export a clean copy without unnecessary metadata.

Resize before crushing quality

Resize proportionally to a useful longest edge, then apply moderate JPEG compression. Start around 80–88% quality and inspect the result.
