How to convert HEIC to JPG on iPhone
Import the HEIC image into FormatFox, choose JPG under Convert to, tap Convert and share the result. The conversion runs on your iPhone. Keep your original HEIC file until you have checked that the JPG opens correctly in the app or website that needs it.
We make FormatFox. This guide explains its workflow and limitations; paid features are noted below.
Get FormatFox on the App StoreBefore you begin
You need an existing image and enough free storage for a second copy. If the original is stored only in iCloud, make it available on the device first. Changing the Camera format affects future photos; it does not convert the photos you already have.
Step by step
Choose the original image
Open FormatFox and select Choose photos for your photo library or Choose files for an image in Files. Start with one image so you can check the result before converting a larger collection. Batch conversion is a Pro feature.
Choose JPG as the output
Under Convert to, select JPG. JPG and JPEG refer to the same image format. Choose PNG instead when preserving transparency is essential; JPEG does not retain an alpha channel.
Decide whether to resize
Keep the original dimensions when you need the full image. Use Resize when the destination has a pixel limit. Resize changes the number of pixels; compression quality changes how those pixels are encoded. Both can affect the result.
Review optional controls
Adjustable Quality and Keep EXIF metadata are Pro features. A lower quality setting may reduce file size but can introduce visible artifacts. Metadata can contain camera details or location, so decide whether the recipient needs it before keeping it.
Convert and check the result
Tap Convert. The results list shows the output filename and before-and-after file sizes. A JPG is not guaranteed to be smaller than its HEIC source. Open the exported copy and inspect text, faces and fine edges at a useful zoom level.
Share the converted copy
Use the share control beside the result to save or send it. In the receiving form, choose the new .jpg file rather than the original .heic file. Keep the original separately if you may want to edit it again.
If an upload still fails
Check the destination’s file-size limit, accepted extensions and image dimensions separately. A valid JPG can still be rejected because it is too large. If necessary, resize the image and convert again. Renaming a .heic file to .jpg does not convert its contents.
If a picker seems empty, check whether the image is in Photos or Files and choose the corresponding import option. For a cloud-only original, download it before expecting the conversion to work offline.
When you may not need a converter
If the recipient already accepts HEIC, sending the original avoids an extra lossy conversion. A converter is useful when a particular website, printer workflow or recipient explicitly needs a JPG copy. FormatFox also offers image-to-PDF conversion when the requested output is a document rather than another image.
Questions that come up
Will my original photo be overwritten?
FormatFox creates an output file for sharing. Treat it as a separate copy and keep your source image until the recipient accepts the result.
Can I convert without an internet connection?
The conversion itself is on-device. An image that still needs downloading from iCloud requires network access first. Sharing through an online service can also require a connection.
Is every conversion option free?
No. Batch conversion, adjustable quality and keeping EXIF metadata are Pro features. Check the App Store for current upgrade pricing.
