Quick answer: Go to Settings → Camera → Formats and choose Most Compatible — new photos will be JPEG. Note this doesn't touch existing photos: convert those in batches with Share → “Convert with PhotoConverter.”

If every photo you take ends up on a Windows PC, a web form, or an Android group chat, shooting HEIC just adds a conversion step to your life. Apple gives you a switch — with a trade-off worth knowing — and it leaves one gap this guide also closes.

The Camera Setting

Open Settings → Camera → Formats and switch from High Efficiency to Most Compatible. From now on, the camera saves JPEG (and video as H.264). The trade-off is honest: JPEGs are roughly twice the size of the equivalent HEIC, so your storage and iCloud fill about twice as fast. Some capture modes that depend on the high-efficiency pipeline can also be restricted.

What the Setting Doesn't Fix

Every photo you've already taken is still HEIC. The setting only affects future shots — your camera roll's history keeps its format. That's the gap batch conversion closes.

Convert the HEIC Photos You Already Have (Step by Step)

  1. Select existing HEIC photos in PhotosPick an album, a trip, or everything you're about to share — batches of dozens are fine.
  2. Tap Share → “Convert with PhotoConverter”The extension loads your selection instantly, right in the share sheet.
  3. Choose JPEG, keep original qualityFull-size, maximum-quality JPEGs are visually identical to the HEIC originals.
  4. Convert and save backOne tap converts the whole batch on-device and saves the JPG copies to your library.

The setting fixes future photos; batch conversion fixes the past.

The Middle Path Most People Actually Want

Consider leaving the camera on High Efficiency and converting on demand instead: you keep the 2× storage savings on thousands of photos and spend one tap on the handful that need to be JPG. That's the workflow Photo Converter is built around — details in the HEIC to JPG guide.
