FARBFELD to APNG Converter
Processing entirely on your device — large files may take a moment.
Convert an animated GIF to APNG to keep smooth color and clean transparency while staying animated. If your files are still in FARBFELD format, this page is the shortcut: Farbfeld is the suckless lossless image format — a tiny 16-byte header then uncompressed 16-bit RGBA, trivially parseable in any language with zero dependencies.
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 FARBFELD format
The Farbfeld Lossless Image coder of the ImageMagick set — the lossless-pixel 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
About the APNG format
APNG (Animated PNG) is what GIF should have been: the same PNG file format with an animation extension — every frame in full 24-bit color with 8-bit alpha, no 256-color palette, no binary transparency with jagged edges. All modern browsers render it natively.
GIF has one job APNG does better in every dimension: color fidelity and clean transparency for animation. Converting an animated GIF to APNG keeps every frame but upgrades color depth and kills the halo around transparent edges. The only cost is file size — true color costs bytes.
+Strengths
- ✓Full 24-bit color per frame (no 256-color palette)
- ✓8-bit alpha transparency — no jagged edges
- ✓Native rendering in every modern browser
!Limitations
- −Larger files than GIF for the same animation
- −Legacy tools may show only the first frame
- −Not accepted by some social platforms

There is a concrete reason this conversion exists: Niche format — few modern readers APNG sidesteps that — Full 24-bit color per frame (no 256-color palette) If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this FARBFELD to APNG 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 FARBFELD to APNG?
No — APNG is a lossless format, so every pixel of the converted image matches your original FARBFELD file. You can also adjust the quality/size balance before converting when the target format supports compression.
Can I convert several FARBFELD 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 APNG?
Transparency is kept whenever APNG 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.
