Convert HEIC to JPG on your iPhone

Your iPhone saves photos as HEIC. The upload form wants JPG. That mismatch is the whole reason this app exists, and converting HEIC to JPG on iPhone should take about ten seconds — not a trip to a desktop computer or an upload to a website you have never heard of.

CODEC converts a photo into the exact format and size you need, on the device you are already holding.

The formats, and why they matter

HEIC stores the same image in roughly half the space of a JPG, which is why Apple switched to it. The problem is everything else: government upload forms, older print shops, marketplace listings, university submission portals and a surprising amount of business software still only understand JPG or PNG.

CODEC writes out JPG, PNG, WebP and PDF, and reads rather more than that — it opens Camera RAW files too, so a backlog of CR2, NEF, ARW or DNG files from a Canon, Nikon or Sony body becomes a folder of ordinary JPGs.

Converting a batch, not a photo

One photo is easy. Four hundred is the actual problem.

Select the whole set and convert in a single run. Rename the batch with a pattern, so IMG_4021 becomes something you can find again. Then save that whole arrangement — format, size target, naming — as a recipe, and next month's batch takes one tap instead of a fresh round of fiddling.

When the file has to be under a specific size

Plenty of forms refuse anything over 1 MB or 2 MB, and offer no help getting there. Guessing at a quality slider and re-exporting until something fits is a miserable way to spend a morning.

Give CODEC a target size instead. It adjusts the compression until the output lands under the limit. You can also resize by pixel dimensions or by percentage when the requirement is about dimensions rather than bytes.

What happens to your photos

Conversion runs on the device. No servers, no uploads, no account to create, and nothing to sign in to. CODEC also has permission only to add to your photo library, never to read it.

Two optional AI tools are the exception, and worth knowing about: AI renaming and AI alt text send a compressed copy of the image for processing, and store nothing. If you would rather nothing left the device at all, simply do not use those two features — everything else works exactly the same.

There is also a metadata step worth remembering. A photo straight from a phone usually carries the GPS coordinates of where it was taken. CODEC can strip EXIF and location data on the way out, which matters more than most people expect when selling something online or sending a picture of a house.

Who ends up using it

Photographers clearing a RAW backlog. Sellers preparing listings that must be JPG. Students compressing scans to fit a submission limit. And a great many people who simply discovered, at an inconvenient moment, that their phone says HEIC when a website wants JPG.
