PFM 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 PFM format, this page is the shortcut: PFM (Portable Float Map) stores pixels as raw 32-bit floats — the lossless hand-off format for HDR pipelines, radiance research and render passes, riding the same family spirit as PBM/PGM/PPM.
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 PFM format
PFM (Portable Float Map) stores pixels as raw 32-bit floating-point values — no palette, no compression tricks, just the numbers. It belongs to the Netpbm family (PBM/PGM/PPM) and is the lingua franca for handing high-dynamic-range data between renderers, tone-mapping experiments and radiance research scripts.
Because the values are floats, a PFM can hold sunlight and candlelight in the same image without clipping. Viewers rarely open it directly: convert to PNG or JPG to get a tone-mapped preview of the same data.
+Strengths
- ✓Full floating-point precision
- ✓Dead-simple text/binary layout
- ✓Widely read by research tooling
!Limitations
- −Enormous files (16 bytes per pixel)
- −Almost no viewer 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 PFM to APK?
Converting makes sense where the strengths of APK meet what PFM cannot give you. Everything an Android app ships Meanwhile Enormous files (16 bytes per pixel) One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this PFM 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 PFM to APK?
No — APK is a lossless format, so every pixel of the converted image matches your original PFM file. You can also adjust the quality/size balance before converting when the target format supports compression.
Can I convert several PFM 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.
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.
