The fastest way: use the built-in Photos app to export

Your iPhone stores photos in HEIC format by default, but you can convert them to JPEG directly in the Photos app without downloading anything. Open the photo you want to convert, tap the three dots in the top right, select "Info," and look for the file format listed there. If it shows HEIC, you'll need to export it as JPEG instead of just saving a copy.

The actual conversion happens when you share the photo. Tap the share button (the box with an arrow), scroll down and tap "Save to Files," then choose a location like iCloud Drive or On My iPhone. Before you tap "Save," the system will ask what format you want — select JPEG from the dropdown menu. This creates a new JPEG version without changing your original photo.

This method works for single photos or small batches. If you need to convert dozens of photos at once, the Photos app becomes tedious, and you'll want a different approach.

Key Takeaways

  • The Photos app can export individual photos as JPEG by using the Share button and selecting Save to Files, then choosing JPEG format before saving.
  • Your iPhone's Settings app has a Camera option that lets you set new photos to save as JPEG instead of HEIC, though this affects only photos taken after you change it.
  • Third-party apps like Image Converter, Convertio, or CloudConvert can batch-convert multiple photos to JPEG faster than doing them one at a time.
  • Converting to JPEG makes files smaller and compatible with older devices and websites, but you lose some image detail compared to HEIC.

Change your camera settings to shoot JPEG from now on

If you want all your new photos to be JPEG instead of HEIC, you can change this in Settings. Open Settings, scroll to Camera, tap Formats, and select "Most Compatible" instead of "High Efficiency." This tells your iPhone to save new photos as JPEG automatically.

The trade-off is file size. HEIC files are smaller than JPEG for the same image quality, so switching to JPEG means photos will take up more space on your phone. If storage is tight, you might want to keep HEIC for new photos and convert only the ones you need to share.

This setting change only affects photos you take after you make the change. Photos already on your phone stay in their original format unless you convert them individually.

Use a third-party app for converting many photos at once

If you have a folder of 20 or 50 photos that all need to be JPEG, doing them one at a time in the Photos app will take an hour. Apps like Image Converter (free with ads, paid version available), Convertio, or CloudConvert let you select multiple photos and convert them all to JPEG in a few taps.

Image Converter is the simplest for iPhone users. Open it, tap the plus button, select multiple photos from your library, choose JPEG as the output format, and tap Convert. The app saves the converted files to your phone or to iCloud Drive depending on what you choose.

Convertio and CloudConvert are web-based, so you upload photos through your phone's browser instead of installing an app. They work well if you only convert photos occasionally and don't want to take up phone storage with a dedicated app.

Understand what you're trading off when you convert to JPEG

HEIC files hold more color information and detail than JPEG in the same file size, which is why Apple switched to it. When you convert HEIC to JPEG, you're compressing the image and losing some of that detail. For photos you're posting to social media or sending to friends, you won't notice the difference. For photos you're printing large or editing heavily, the loss matters.

JPEG files are also larger than HEIC files, so converting means your phone uses more storage. If you're converting dozens of photos, you might free up space by deleting the HEIC originals after conversion — but only if you're sure you don't need them later.

The main reason to convert is compatibility. Older phones, Windows computers, and some websites don't read HEIC files. If you're sending photos to someone with an older device or uploading to a website that rejects HEIC, JPEG is the safer choice.

Email and messaging apps often convert automatically

If you're sending a photo through Mail, Messages, or WhatsApp, your iPhone may convert it to JPEG automatically without you doing anything. This depends on the app and your settings. Mail usually converts HEIC to JPEG when you attach a photo, while Messages sometimes keeps HEIC depending on whether the recipient has an iPhone.

You can check what format was sent by asking the person who received it to tell you the file extension, or by looking at the file properties on a computer. If the app didn't convert it and you need JPEG, use the export method described above instead of relying on the app to do it for you.

Store converted photos where you can find them again

When you export a photo as JPEG, decide where it goes before you save. The Files app on your iPhone lets you create folders in iCloud Drive or On My iPhone to organize converted photos by date, project, or purpose. This keeps them separate from your original HEIC files so you don't get confused about which version is which.

If you're converting photos to share with someone, save them to a shared iCloud folder or AirDrop them directly instead of emailing them one at a time. This is faster and keeps your phone's storage from filling up with copies.

Frequently Asked Questions

Can I convert JPEG back to HEIC?

No, and you wouldn't want to. JPEG is a lower-quality format, so converting it back to HEIC won't restore the detail you lost. If you need both versions, keep your original HEIC file and create a JPEG copy instead of replacing it.

Will converting to JPEG make my photos look worse?

For most uses, no. The difference is visible only in large prints or heavy editing. For social media, email, and messaging, JPEG looks the same as HEIC to the human eye.

Do I need to delete the original HEIC file after converting?

No, but you can if you need storage space. Keep the HEIC if you might edit the photo later or want to preserve the highest quality version. Delete it only if you're sure you won't need it.

What if an app won't let me choose JPEG format when exporting?

Some apps export only in their own format. Try a different app, or use the Files app method described above to convert after exporting. If the app exports to HEIC, you can then convert that file to JPEG using Image Converter or another third-party tool.

Can I batch-convert photos using Shortcuts?

Yes, if you're comfortable with the Shortcuts app. You can create a shortcut that converts multiple HEIC photos to JPEG automatically, but setting it up takes more time than using a dedicated app for most people.
