Why your iPhone photos won’t upload

If this keeps happening to you, you are not doing anything wrong. Most of the time the photo itself is fine, but the website you are uploading to does not accept the iPhone format.

What is usually happening

Your iPhone saved the image as HEIC, but the site only allows JPG or PNG.
The upload system is older (common in school, work, and government portals).
The file is valid, but the platform gives a vague "failed" or "unsupported" message.

The fastest fix

Open iPhone Photo Fix.
Pick the photos that are failing.
Leave format on JPG, then share or download.

Which format should you pick?

JPG: best default for almost everything.
PNG: best for screenshots and text-heavy images.
PDF: useful for print workflows or document uploads.
