HEIF to XV Converter
Processing entirely on your device — large files may take a moment.
Convert to XV thumbnails for legacy UNIX galleries. 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.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

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 XV format
The XV Thumbnail coder of the ImageMagick set — the unix-gallery format is written natively by the magick.wasm engine, entirely in your browser.
Obscure coder formats like this are exactly what template-driven converters list and never actually convert — here it really works.
+Strengths
- ✓Written natively by ImageMagick
- ✓Runs entirely in your browser
- ✓Free, private, no watermarks
!Limitations
- −Niche format — few modern readers
- −Feature subset varies by coder
- −Keep the original for re-editing
Why convert HEIF to XV?
Think of it as moving your file to the container that fits the job. Windows and many web services need extras to open it XV works differently: Written natively by ImageMagick If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this HEIF to XV 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 XV?
No — XV 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.
Will transparent areas survive the conversion to XV?
Transparency is kept whenever XV 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.
Can I convert several HEIF files at once?
Yes — drop as many files as you like into the tool and they are converted in one batch. When more than one file comes out, everything is bundled into a ZIP for a single download.
