Convert RAF to APNG Online

Make an APNG from Fujifilm RAF Photos

Turn a sequence of Fujifilm RAF raw photos into one animated PNG: upload your RAF frames in shooting order, set a frame rate, and download a single looping APNG. Each RAF is demosaiced and rendered to an 8-bit sRGB frame, then stacked into the animation — ideal for previewing an interval-timer timelapse without round-tripping through Lightroom or Capture One. Upload one RAF and you get a clean one-frame (static) APNG; upload several and each becomes a frame.

How to Convert RAF to APNG

1. Upload Your RAF Files: Drag and drop or click "Add Files" to add your Fujifilm RAF photos. They become frames in the order you add them, so arrange the sequence before converting (only .raf inputs are accepted).
2. Set the Framerate: Pick a value from the Framerate dropdown — 10 FPS (Recommended) for a smooth loop, or drop to 1 FPS for a slideshow and up to 50 FPS for fast motion. The frame rate sets how long each rendered RAF is shown.
3. Adjust Image Quality, Resolution, or Colors (Optional): Use Image quality (%) to trade detail for a smaller file, set a Preset Resolution or Width x Height to resize every frame, or reduce Colors with dithering only if you need to shrink the output further.
4. Convert and Download: Click Convert and save your APNG. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. No sign-up, no watermark.

APNG vs GIF for RAF Photo Frames

Frequently Asked Questions

How do I combine multiple RAF photos into one animated APNG?

Add every RAF you want as a frame before you convert — the upload order is the playback order. Each raw photo is rendered to one frame, and the Framerate setting controls how long each frame is shown. A single uploaded RAF produces a valid one-frame (static) APNG, which is useful if you just want a lossless PNG from one raw file.

What happens to the 14-bit RAF data and X-Trans color when I convert?

A RAF stores roughly 14-bit raw sensor readings from Fujifilm's X-Trans color filter array, which a display cannot show directly. The converter demosaics each RAF and renders it to a standard 8-bit-per-channel sRGB frame, the same color space your browser and APNG use. You keep the full visible detail of the scene, but the extra raw editing latitude (and embedded Film Simulation tags) lives in the RAF and does not carry into the APNG — keep the originals if you plan to re-edit.

Will my APNG have transparent areas?

No. A rendered RAF photo is fully opaque, so there is nothing transparent to carry over. APNG's 8-bit alpha channel only matters when the source already has transparency. If you need transparent frames, start from PNG instead with PNG to APNG.

Why pick APNG over GIF for raw photo frames?

RAF photos are full-color, and GIF caps every frame at 256 colors, which adds visible banding to skies, skin tones, and smooth gradients. APNG stores full 24-bit color losslessly, so the frames look like the rendered photos. In our testing, a 5-frame 1080p RAF sequence produced an APNG with no posterization, where the GIF version showed dithering across the sky.

Which browsers and apps play APNG files?

Chrome 59+, Firefox 3+, Safari 8+, Edge 79+, and current Opera play APNG natively — about 94.7% of users worldwide per caniuse. In an app or older browser that does not understand APNG, the file gracefully falls back to showing its first frame as a normal still PNG instead of breaking. If you only need a single still image from one RAF, use RAF to PNG instead.
