HEIC to JPG Converter
Convert iPhone HEIC photos to JPG or PNG in your browser. Batch convert, pick the quality, download as a ZIP. Your photos are never uploaded.
What HEIC to JPG Converter Does
This HEIC to JPG converter turns iPhone and iPad photos into JPG or PNG files that open everywhere: Windows, older Macs, web forms, printers and photo kiosks. The converter itself runs inside your browser, so your photos are decoded on your own device and are never uploaded to anyone’s server.
HEIC is Apple’s file extension for HEIF, the High Efficiency Image File Format. Since iOS 11, iPhones that support it save photos as HEIF by default when the camera is set to High Efficiency, because it stores the same picture in noticeably less space than JPEG. The catch is compatibility: many programs and upload forms still accept only JPEG or PNG.
You can convert as many photos as you like in one go and download them individually or together as a single ZIP. A HEIC file that contains more than one image, such as a burst, is split into numbered JPGs rather than silently keeping only the first.
How to Use HEIC to JPG Converter
- Choose JPG or PNG, and a JPG quality if needed
- Drop your HEIC photos onto the box or click to choose them
- Wait a moment while each photo converts in your browser
- Download photos one by one, or all at once as a ZIP
How HEIC to JPG Converter Works
Decoding HEIC in the browser
load the heic2any decoder (libheif compiled to JavaScript, about 1.4 MB, fetched on first use) → decode every image in the HEIF container → encode each as JPEG (quality 92 by default) or PNG → name the files after the original → download singly or as one ZIP
- HEIF container
- HEIC is HEVC-compressed image data in a HEIF container, which can hold more than one image. Each image becomes its own file.
- naming
- IMG_0412.HEIC becomes IMG_0412.jpg. A container with several images gives IMG_0412-1.jpg, IMG_0412-2.jpg and so on.
- mislabeled files
- A file that is really a JPEG or PNG with a .heic name is detected and you are told to rename it, rather than getting a generic error.
Worked example
Three iPhone photos: IMG_0410.HEIC, IMG_0411.HEIC, IMG_0412.HEIC, output JPG at 92%
- The decoder downloads once, then the three files are converted one after another
- Each row shows Waiting…, then Converting…, then its original size and converted size side by side
- The EXIF data (date taken, camera, GPS location) is not copied into the JPGs
Result: IMG_0410.jpg, IMG_0411.jpg and IMG_0412.jpg, downloadable one by one or together as converted-photos.zip. Nothing left your device.
HEIC vs JPG vs PNG
| HEIC (HEIF) | JPG | PNG | |
|---|---|---|---|
| Compression | Lossy, very efficient | Lossy | Lossless |
| Typical file size | Smallest | Larger than HEIC | Largest (often several times JPG) |
| Opens on Windows, web forms, printers | Often not without extensions | Everywhere | Almost everywhere |
| Transparency | Supported | No | Yes |
| Best for | Storing photos on Apple devices | Sharing and uploading photos | Screenshots, graphics, editing without further loss |
Stop Your iPhone Saving HEIC
| Step | Where |
|---|---|
| 1 | Open Settings |
| 2 | Tap Camera, then Formats |
| 3 | Choose Most Compatible — new photos save as JPEG |

How to Read Your Result
Choosing a JPG quality
The default of 92% keeps photos visually identical to the original at a reasonable size. 80–85% roughly halves the file again with little visible change on phone screens — good for email or web uploads with size limits. 100% gives the largest JPG without meaningful gain; choose PNG if you need no further loss at all.
What happens to photo metadata
The converted file carries the image only. The date taken, camera model and GPS coordinates stored in the HEIC’s EXIF data are not copied across. That is useful when you want to share a photo without revealing where it was taken; keep the original if you need that information for your library.
Limitations & Accuracy Notes
- EXIF metadata (date, camera, location) is not preserved in the converted files.
- Live Photo motion and depth data are not converted; only the still image is.
- Very large batches are limited by your device’s memory because conversion happens in the browser.
- HEIC files with a wide-color or HDR gain map are converted to standard JPEG, which cannot hold that extra range.
Frequently Asked Questions
Are my photos uploaded to a server?
No. The HEIC decoder runs inside your browser, so photos are converted on your own device and never leave it. That matters for personal photos, which is exactly what HEIC files usually are.
Why are my iPhone photos in HEIC format?
Since iOS 11, iPhones and iPads that support it save photos as HEIF/HEIC by default under the “High Efficiency” camera setting, because it stores the same image in less space than JPEG. Windows PCs, many websites and older software still cannot open HEIC, which is why converting is often needed.
How do I stop my iPhone from taking HEIC photos?
Open Settings › Camera › Formats and choose Most Compatible. New photos are then saved as JPEG. Existing photos stay HEIC, and iPhones usually convert automatically when you share to apps or computers that need JPEG.
Does converting HEIC to JPG lose quality?
JPEG is a lossy format, so a tiny amount of detail is discarded, but at the default 92% quality the difference is not visible in normal viewing. For no additional loss at all, choose PNG; the files will be several times larger.
Is the photo’s location and date kept?
No. The converted file does not carry over the original EXIF metadata (camera settings, date taken or GPS location). That is a privacy benefit when sharing, but keep the original HEIC if you need the date and place for your photo library.
Why did one HEIC file turn into several JPGs?
A single HEIC container can hold more than one image, such as a burst or an image sequence. Each image inside becomes its own numbered JPG so nothing is silently dropped.
Can I convert many photos at once?
Yes. Drop or select as many HEIC files as you like; they convert one after another and can be downloaded individually or together as one ZIP file. Very large batches depend on your device’s memory.
