iPhone photo to JPG for forms and Windows
iPhones save photos as HEIC to save space. Many government portals, job sites and older Windows computers can't open HEIC, or reject it at upload. Converting to JPG solves this. Add the photos straight from your iPhone, choose JPG and High quality, and the result opens anywhere. If the form then needs a file under a set KB, use Photo to KB next.
A free image converter that doesn't upload your photos, and which format to use
The conversion runs in your browser on your phone or computer. Your photos are not sent to a server, and there is no sign-up. That makes it a practical way to clean up a whole camera roll before sending it to a printer, a shop or a family group.
If you are not sure which format to pick, these rules of thumb cover most cases. Choose JPG for photos of people, places and documents you will upload to a form, send on WhatsApp or print at a shop, because almost every system accepts it. Choose PNG for screenshots with small text, logos, drawings and anything with a see-through background, because it keeps sharp edges exactly. Choose WebP only for your own website or online store, where smaller files help pages open quickly on mobile data. When a portal says it only accepts JPG or JPEG, both names mean the same format, so a converted JPG is fine. Keep your original files too, in case you need another format later.
