How to Convert iPhone Photos for Online Selling
You take great product photos on your iPhone, but every marketplace seems to fight you when you try to upload them — Amazon rejects them outright, Mercari throws an error, Poshmark's website won't take them, and eBay is hit or miss. The common thread: your iPhone saved them as .heic files.
One conversion to JPG solves it for every platform. Here's the whole workflow.

- Click Download all as ZIPto grab the whole batch, then upload to whichever marketplace you're listing on.
Why iPhones save HEIC — and why it breaks marketplaces
Since iOS 11, iPhones default to HEIC because it stores the same quality image in roughly half the file size. Apple optimized for phone storage; marketplaces optimized for the long-standing JPG standard. The result is friction every time you try to sell.
Here's how the major platforms actually handle HEIC:
- Amazon— Does not accept HEIC at all. Takes JPEG, PNG, TIFF, and non-animated GIF, up to 10 MB.
- Mercari— Rejects HEIC. Use JPEG or PNG.
- Poshmark— Doesn't support HEIC for web uploads (listing from a computer); convert to JPG first.
- eBay— Lists HEIC as supported, but uploads fail on Firefox, some Safari versions, and the legacy listing tool.
- Etsy— Lists HEIC as supported, but handling is inconsistent across browsers and devices.
- Shopify— Lists HEIC as supported, but uploads are unreliable in practice; Shopify recommends JPG.
The pattern is clear: HEIC is either rejected or unreliable, while JPG works everywhere. Converting once saves you from chasing platform-specific quirks.
Stop the problem at the source
If you sell often, set your iPhone to capture JPGs directly: open Settings → Camera → Formats and choose Most Compatible. New photos save as JPG. Photos already in your camera roll remain HEIC, so use the converter for your existing shots.
Compress your photos so listings load fast
High-resolution iPhone JPGs can be several megabytes each. Buyers (and search rankings) reward fast-loading listings, so run your converted photos through the free image compressor at 80–85% quality. You'll cut file sizes by half or more with no visible difference, keeping you under every marketplace's limit and making uploads faster.
Convert HEIC to JPG once, compress for speed, and your iPhone photos will sell on Amazon, eBay, Etsy, Shopify, Poshmark, Mercari, and anywhere else you list.
