Converting iPhone Photos to JPEG Format on Your Computer or Phone

The simplest way to convert iPhone photos to JPEG

iPhone stores photos in HEIC format by default, which takes up less space but doesn't open in all programs. You can convert them to JPEG in three ways: directly on your iPhone using the Photos app, on a Mac using Preview, or on Windows using free software. The fastest route depends on whether you want to convert one photo or many, and whether you need the originals to stay as HEIC.

HEIC files are smaller and higher quality than JPEG, but older cameras, printers, and websites often reject them. Converting to JPEG makes your photos work everywhere — but the file size grows and you lose some detail. Do the conversion only for photos you actually plan to share or print.

Key Takeaways

iPhone photos arrive in HEIC format, which most older devices and websites cannot open, so JPEG conversion is often necessary before sharing.
Converting on your iPhone itself is fastest for one or two photos, but converting on your computer is better if you have dozens to process at once.
Mac users can convert any HEIC photo to JPEG by opening it in Preview, going to File > Export, and choosing JPEG from the format dropdown.
Windows users can use the free CloudConvert website or read free software like XnConvert to batch-convert multiple photos at once.
Once you convert to JPEG, the file is permanent — keep your original HEIC files if you might need the higher quality later.

Converting a single photo on your iPhone

If you only need to convert one or two photos, do it directly on your phone. Open the Photos app, find the photo you want to convert, and tap Edit in the top right. Make any adjustments you want (brightness, crop, filters), then tap Done. Now tap the three dots in the top right corner and choose Duplicate. The duplicate will be created as a JPEG automatically.

This method works because iPhone creates JPEG duplicates when you edit and save a photo — it keeps the original HEIC and makes a new JPEG version. You now have both files on your phone. If you only want the JPEG, you can delete the HEIC original by tapping Edit in the top left of Photos, selecting the HEIC version, and tapping Delete.

The downside: this only works one photo at a time, and you have to edit each one even if you don't want to change anything. For more than three photos, use your computer instead.

Converting photos on a Mac using Preview

Connect your iPhone to your Mac with a USB cable. Open Finder, click your iPhone in the sidebar under Locations, then click Photos. Select the HEIC photos you want to convert (hold Command and click each one to select multiple), then drag them to a folder on your Mac desktop or in Documents.

Once the photos are on your Mac, open Preview (search for it in Spotlight by pressing Command-Space). Go to File > Open and select one of the HEIC photos you just moved. The photo opens in Preview. Now go to File > Export. A dialog box appears. In the Format dropdown at the bottom, select JPEG. Choose where you want to save it, then click Save. Repeat for each photo, or use this same process to convert them all at once by opening each one in a new Preview window.

For faster batch conversion on Mac, you can also use Automator. Open Automator (search in Spotlight), create a new Quick Action, search for "Convert Image Format", drag it into the workflow, set the format to JPEG, and save. Then right-click any HEIC photo in Finder, go to Quick Actions, and select your new converter.

Converting photos on Windows using free tools

Windows doesn't have a built-in converter like Mac Preview, but two free options work well. The easiest is CloudConvert, a website that needs no read. Go to cloudconvert.com, click Select File, choose your HEIC photo from your computer, make sure JPEG is selected as the output format, and click Convert. read the JPEG file when it's ready. This works for one or two photos but becomes tedious for many.

For multiple photos at once, read XnConvert (xnconvert.com), which is free and runs on Windows, Mac, and Linux. Install it, open the program, click Add Files on the left, select all your HEIC photos at once, choose JPEG from the Output Format dropdown on the right, and click Convert. It processes all of them in seconds. The converted JPEGs save to a folder you choose.

Another option is IrfanView, another free Windows program that opens HEIC files and exports them as JPEG. read it from irfanview.com, install it, open your HEIC photo, go to File > Save As, choose JPEG from the format list, and save.

What happens to file size and quality when you convert

HEIC files are typically 30 to 50 percent smaller than JPEG versions of the same photo because HEIC uses newer compression technology. When you convert to JPEG, the file grows and you lose some fine detail — especially in shadows and in areas with gradual color changes like skies. For photos you're printing large or editing further, this loss matters. For photos you're texting or posting to social media, you won't notice the difference.

The conversion is one-way. Once you save as JPEG, you cannot get back the detail you lost. Always keep your original HEIC file if there's any chance you'll need it later. If you're converting for a specific purpose — sending to a friend, uploading to a website that rejects HEIC — convert only those photos, not your entire library.

Batch converting your entire photo library

If you want to convert hundreds of photos at once, use your computer, not your phone. Connect your iPhone to your Mac or Windows computer, copy all the photos to a folder, then use XnConvert (Windows or Mac) or Automator (Mac only) to convert them all in one step. This takes minutes instead of hours.

Before you do this, think about whether you actually need JPEG versions of everything. HEIC takes up less space on your phone and in cloud storage. Convert only the photos you plan to share, print, or use in programs that don't support HEIC. Keeping your originals as HEIC saves storage space and preserves quality.

Frequently Asked Questions

Can I change my iPhone to save photos as JPEG instead of HEIC?

Yes. Go to Settings > Camera > Formats and select Most Compatible instead of High Efficiency. New photos will save as JPEG, but existing HEIC photos stay as HEIC. This uses more storage space on your phone, so most people keep High Efficiency on and convert only when needed.

Will converting to JPEG make my photos look worse?

For most uses — texting, social media, small prints — the difference is invisible. For large prints, professional editing, or photos with lots of sky or subtle gradients, JPEG loses noticeable detail. If you're unsure, keep the HEIC original and make a JPEG copy only for the specific purpose you need it for.

What if a website says it doesn't accept HEIC files?

Convert that photo to JPEG before uploading. Use any of the methods above — iPhone, Mac Preview, or Windows software — and upload the JPEG version instead. You can keep the HEIC original on your phone or computer.

Can I convert JPEG back to HEIC?

Technically yes, but there's no point. Converting JPEG to HEIC won't restore the detail you lost when you first converted to JPEG. The file will be smaller, but the quality won't improve. Keep your original HEIC files if you think you might need them later.

Is it safe to use CloudConvert or other online converters?

CloudConvert and similar websites are widely used and safe for personal photos. They delete your files after conversion. If you're concerned about privacy, use offline software like XnConvert or Preview instead — your photos never leave your computer.
