HEIF to JP2 Converter
Processing entirely on your device — large files may take a moment.
Convert photos or scans to JP2 for archival storage, or JP2 to JPG/PNG for everyday viewing. If your files are still in HEIF format, this page is the shortcut: HEIF is the family container HEIC belongs to — same HEVC-based compression, often used by name on Android and camera firmware where HEIC is the Apple branding.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.
How HEIF compares to JP2
| HEIF | JP2 | |
|---|---|---|
| Compression | Lossy HEVC (lossless variant exists) | Wavelet (lossy + lossless) |
| Transparency | Supported | Supported |
| Animation | Supported (bursts/sequences) | Not supported (MJ2 is separate) |
| Metadata | EXIF, depth maps, HDR gain maps | XML boxes (EXIF/GPS) |
| Best for | iPhone photo storage | Archives, medical, cinema |

About the HEIF format
HEIC (High Efficiency Image Container) is the HEIF container carrying HEVC-compressed image data, and it has been the default photo format on iPhones since iOS 11. At equivalent quality it stores photos in roughly half the space of JPG, keeps 10-bit color and HDR information intact, and can hold multiple images — bursts,Live Photos pairs, even depth maps — in one file.
Its weakness is everything outside Apple's ecosystem. Windows needs an extension from the Store to preview it natively, many web services still reject the upload, and HEVC's patent licensing slowed hardware adoption on non-Apple devices. Android 9+ phones generally handle it, but the desktop web remained JPG territory for years.
+Strengths
- ✓About half the size of JPG at the same quality
- ✓10-bit color and HDR survive the pipeline
- ✓One file can hold bursts, sequences and depth data
!Limitations
- −Windows and many web services need extras to open it
- −HEVC patent licensing complicated adoption outside Apple
- −Thumbnail and preview performance on old hardware is poor
About the JP2 format
JPEG 2000 (JP2) replaced JPG's DCT blocks with wavelet transforms: at the same bitrate it shows fewer blocky artifacts, and its lossless mode compresses better than JPG ever could. It was the format of early digital cinema and remains common in archives, medical systems and geospatial pipelines.
Browser support never arrived — Chrome, Firefox and Safari all skip it — so a JP2 file is often invisible on the web. Converting JP2 to JPG or PNG makes archival material viewable anywhere; converting the other way gives long-term storage better compression.
+Strengths
- ✓True lossless mode
- ✓Better quality per byte than JPG
- ✓ROI / progressive decoding built in
!Limitations
- −No browser support
- −Slow to encode compared to JPG
Why convert HEIF to JP2?
There is a concrete reason this conversion exists: Windows and many web services need extras to open it JP2 sidesteps that — True lossless mode If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this HEIF to JP2 converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will I lose quality converting HEIF to JP2?
No — JP2 is a lossless format, so every pixel of the converted image matches your original HEIF file. You can also adjust the quality/size balance before converting when the target format supports compression.
What happens to EXIF data and other metadata?
Conversions here re-encode the image, and re-encoding generally does not carry the original metadata over. If the EXIF data of your HEIF files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
Will transparent areas survive the conversion to JP2?
Transparency is kept whenever JP2 actually supports an alpha channel. If the target format has none (like JPG), transparent areas are flattened onto a white background — that is a property of the format, not of this tool.
