VIFF to APK Converter
Processing entirely on your device — large files may take a moment.
Repack an APK as ZIP to inspect its manifest and assets (not for reinstalling). If your files are still in VIFF format, this page is the shortcut: VIFF is the image format of the Khoros software system, a research toolkit from the early days of scientific visualization. Still found in legacy academic image-processing datasets.
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 VIFF format
VIFF is the image format of the Khoros software system, a visual-programming environment built for scientific image processing in the late 1980s and 1990s. Its files carry raster data plus optional attribute lists, and it survives today mostly in older academic datasets and image-processing course material.
Modern software rarely opens VIFF without help. Converting VIFF to PNG puts legacy research imagery into a format every viewer, notebook and browser understands — useful when reviving old datasets or coursework.
+Strengths
- ✓Holds multi-band scientific raster data
- ✓Attribute lists travel with the image
- ✓Simple, fully documented binary layout
!Limitations
- −Tied to discontinued Khoros tooling
- −No browser or OS support
About the APK format
An APK is Android’s install package: a ZIP holding AndroidManifest.xml, compiled DEX bytecode, native libraries and assets. Unpacking one is the standard first step of security review, compatibility checks and asset recovery.
One honest limit: unpacking is inspection, not installation — a repacked ZIP cannot be installed back onto a phone, and the page says so.
+Strengths
- ✓Everything an Android app ships
- ✓ZIP-based, easy to unpack
- ✓Manifest readable as XML
!Limitations
- −DEX bytecode is not human source
- −Repack cannot reinstall
Why convert VIFF to APK?
Converting makes sense where the strengths of APK meet what VIFF cannot give you. Everything an Android app ships Meanwhile Tied to discontinued Khoros tooling One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this VIFF to APK 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 VIFF to APK?
No — APK is a lossless format, so every pixel of the converted image matches your original VIFF file. You can also adjust the quality/size balance before converting when the target format supports compression.
Will transparent areas survive the conversion to APK?
Transparency is kept whenever APK 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.
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 VIFF files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
