How to Convert HEIC to JPG on Any Device
If you have ever tried to upload an iPhone photo to a website or share it with a Windows user and gotten an error, you have probably encountered the HEIC format. It is a better image format in many ways, but it is not accepted everywhere. Converting to JPG solves the compatibility problem instantly. A browser-based converter handles the entire job locally without uploading your photos to a server.
Why iPhones use HEIC
HEIC (High Efficiency Image Container) has been the default photo format on iPhones since 2017 (iOS 11). Apple chose it because HEIC files are roughly half the size of equivalent JPEGs with no visible quality difference. That means your phone can store twice as many photos.
The downside: not everything supports it. Windows (older versions), many websites, some email clients, and most online forms expect JPG or PNG.
When you need to convert
- Uploading to a website that does not accept HEIC (most form uploads still expect JPG or PNG)
- Sharing with Windows users who cannot open HEIC files without installing additional software
- Printing services that require JPG format
- Social media: while most major platforms now accept HEIC, some smaller sites do not
- Email attachments: JPG is universally compatible
- Older photo editing software: many non-Adobe apps still cannot open HEIC
- Embedded systems and IoT: digital photo frames, e-ink displays, embedded device displays
- Web display: HEIC is not yet a standard browser image format (HTML
<img src="...heic">does not work universally)
How to convert HEIC to JPG
- Upload your HEIC files: drag and drop or click to browse. You can upload multiple files at once.
- Adjust quality: use the quality slider to balance file size and image quality. 85-90% preserves excellent quality with a reasonable file size.
- Convert and download: click "Convert" and download your JPG images. Multiple files come as a ZIP.
A brief history of the HEIC format
HEIC is Apple's branding for HEIF (High Efficiency Image Format), a 2015 ISO/IEC standard developed by MPEG (the same group behind H.264 and H.265 video). HEIF uses the same HEVC (H.265) compression algorithm as 4K Blu-ray video, applied to single images.
Apple was the first major adopter in 2017 with iOS 11, choosing HEIC over JPEG to save device storage. The math is straightforward: a typical HEIC is 1-2 MB where the same JPEG would be 3-5 MB. Across thousands of photos on a phone, that doubles effective capacity.
Other vendors have been slower to adopt:
- Samsung: HEIF supported from Galaxy S10 (2019) but not default
- Google Android: HEIC support added in Android 10 (2019), default on Pixel 6 (2021) and later
- Microsoft Windows: HEIF/HEIC viewing native in Windows 11 (2021); paid codec required on Windows 10
- Web browsers: Safari supports HEIC natively (since macOS Big Sur 2020 / iOS 11 2017). Chrome and Firefox still do not support HEIC for
<img>tags in 2026, though both can preview HEIC files via Drag-and-drop.
The format will likely become universal eventually, but in 2026 JPEG remains the lowest common denominator that works literally everywhere.
File size comparison
A typical 12 MP iPhone photo:
| Format | Typical size | Notes |
|---|---|---|
| RAW (.HEIF + ProRAW) | 25-35 MB | Pro/Pro Max iPhones only |
| HEIC | 1-2 MB | iPhone default |
| JPEG (95% quality) | 4-5 MB | Equivalent quality |
| JPEG (85% quality) | 2-3 MB | Slight visible artifacts |
| JPEG (75% quality) | 1-2 MB | Visible artifacts |
| WebP (90% quality) | 1.5-2.5 MB | Modern alternative |
| AVIF (90% quality) | 1-1.5 MB | Newest format |
HEIC's compression advantage diminishes for screenshots, documents, and photos with flat colors. It shines on natural photos with gradients (skies, skin tones, foliage).
Preventing the problem on iPhone
You can set your iPhone to save photos as JPG instead of HEIC:
- Open Settings
- Go to Camera > Formats
- Select Most Compatible
This saves photos as JPG directly. The trade-off is larger files on your phone, roughly double the storage per photo.
A second approach: leave HEIC enabled for storage, but configure AirDrop and email to automatically convert to JPEG when sharing. Settings > Photos > "Transfer to Mac or PC" > Automatic. This option converts to JPG only when transferring off the device.
What converting preserves
The HEIC-to-JPG conversion preserves most of what matters:
- Image content: pixels are decoded and re-encoded, identical-looking output
- EXIF metadata: camera model, lens, shutter speed, aperture, ISO, GPS location (privacy-sensitive)
- Date taken: original timestamp from EXIF
- Color profile: typically sRGB or Display P3
- Orientation: portrait/landscape flag preserved
What is lost:
- Burst mode: HEIC can store multiple bracketed exposures; JPG saves only one
- Live Photo motion: the 3-second video clip attached to Live Photos
- Depth map: portrait-mode background-blur data, lost when converted to JPG
- HDR tone-mapping: extended dynamic range information beyond standard sRGB
For most ordinary photo sharing, none of these losses matter. For pro photography workflows, keep the HEIC and convert only the specific images you need to share.
Common pitfalls
- EXIF location data leaks: HEIC photos contain GPS coordinates of where they were taken. JPG converters preserve this by default. If you are sharing a photo of your home, remove EXIF first.
- Live Photo flattened to still: the motion component of a Live Photo is lost during conversion. If you want to preserve the motion, convert separately to MOV.
- Color profile mismatch on older displays: HEIC photos shot in Display P3 (Apple wide-gamut) can look slightly different on sRGB-only displays after conversion. Most conversion tools handle this correctly; verify if colors look off.
- HEIC from Samsung is HEIF, not HEIC: technically the same format, but Samsung extensions sometimes confuse Apple-focused converters. Most universal converters handle both fine.
- File size after conversion: JPG at high quality (95%) is ~3x larger than the source HEIC. If you need small files, accept some JPG compression.
- Some converters re-encode at low quality silently: verify the output looks right before deleting originals. Default 85% quality is usually a safe choice.
- Batch conversion order: most tools preserve filename order in the output ZIP. If your photos are timestamp-named (IMG_0001.heic, IMG_0002.heic), the ZIP order matches your original sequence.
Alternative formats to consider
If you control the destination, JPG may not be the best choice:
- WebP: native in Chrome/Firefox/Edge/Safari 14+, ~30% smaller than equivalent JPG.
- AVIF: native in Chrome 85+/Firefox 113+/Safari 16.4+, ~50% smaller than JPG.
- PNG: lossless, larger than JPG, best for screenshots and graphics.
- HEIC itself: if Safari is the target browser, HEIC works natively and saves bandwidth.
For most non-Apple-controlled destinations (uploading to a website, sharing with mixed-OS users, printing), JPG is still the safest universal choice in 2026.
Tips
- Batch convert: if you have a folder full of HEIC photos, upload them all at once rather than converting one by one.
- Keep quality at 85-90%: this gives you the best balance. Going above 90% makes files much larger with barely visible improvement.
- Use this before printing: photo printing services almost universally expect JPG. Convert before uploading to avoid errors.
- Strip EXIF for online sharing: if you are posting a photo publicly, use a tool that removes EXIF data first. Otherwise you may inadvertently share GPS coordinates.
- Preserve originals: keep the HEIC files even after converting. If you need different quality later (printing, editing), starting from the original HEIC produces better results.
- Test on the target platform: some image-quality issues only appear on specific browsers or print services. Convert one photo first as a test before processing a batch.
Privacy and sensitive photos
The HEIC-to-JPG converter runs entirely in your browser. The photos you upload, intermediate processing, and the converted JPGs all stay on your device. Nothing is uploaded to a server, logged, or shared with anyone.
This matters because photos often contain very sensitive content: family pictures, ID documents being prepared for upload, screenshots with confidential info, medical photos, photos of private locations with GPS-tagged EXIF. Cloud HEIC converters by design upload your photos to their servers, sometimes retain them for "service improvement" or analytics, and some have been caught leaking uploaded images. A browser-based converter has zero exposure: the photo never leaves your machine.
Browser-based conversion also works offline once the page is loaded, useful for converting photos in low-connectivity environments (international travel, airplanes, remote locations).
Frequently Asked Questions
What is a HEIC file?
HEIC (High Efficiency Image Container) is the default photo format on iPhones since iOS 11 (2017). It produces smaller files than JPG at the same quality, but is not universally supported.
Why does my iPhone save photos as HEIC?
Apple uses HEIC because it produces photos that are roughly half the file size of an equivalent JPEG, saving storage space on your device without sacrificing image quality.
Will converting to JPG reduce quality?
There is a small amount of quality loss during conversion because JPG uses lossy compression. At high quality settings (80-90%), the difference is imperceptible to the human eye.
Can I convert multiple HEIC files at once?
Yes. Upload multiple HEIC files and they will all be converted to JPG. Multiple files are downloaded together as a ZIP.
