Convert CR3 to APNG Online

Convert CR3 to APNG Online

Build one animated PNG from a sequence of Canon CR3 raw photos — a timelapse, a burst, or a frame-by-frame loop — with each CR3 becoming one frame. The raw sensor data is demosaiced and rendered to an 8-bit sRGB image first, then stacked into a single APNG that keeps full 24-bit color and lossless frames, so skies and skin tones stay smooth instead of being crushed to GIF's 256-color palette. Upload one CR3 and you get a valid one-frame (static) APNG; upload several and they play back in the order you add them.

How to Convert CR3 to APNG

1. Upload Your CR3 Files: Drag and drop or click "Add Files" to add your Canon raw photos. They become frames in upload order, so arrange them before converting — drop in a whole burst or timelapse set and they queue as one animation.
2. Set the Framerate: Pick a value from the Framerate dropdown — 10 FPS (Recommended) for a typical loop, or step down toward 1 FPS for a slideshow and up toward 50 FPS for fast motion. This sets how long each CR3 frame 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 shrink the large raw dimensions to a web size, or leave Colors on ORIGINAL for full color.
4. Convert and Download: Click Convert and save your APNG. Files upload over an encrypted connection, are processed on our servers, and are deleted automatically after a few hours. No sign-up, no watermark.

APNG vs GIF for CR3 Photo Frames

Frequently Asked Questions

How do I combine multiple CR3 files into one animated APNG?

Add every CR3 you want as a frame before you convert — the upload order is the playback order. Each raw file is rendered to one frame, and the Framerate setting controls how long each frame is shown. A single uploaded CR3 produces a valid one-frame (static) APNG, so this tool doubles as a plain CR3-to-PNG export when you add just one file.

Why pick APNG over GIF for a CR3 timelapse?

Canon raw photos are full continuous-tone color, and GIF caps every frame at 256 colors, which adds visible banding to skies, skin tones, and out-of-focus areas. APNG stores full 24-bit color losslessly, so a rendered raw sequence looks like the originals. In our testing, a 5-frame 1080p CR3 timelapse exported as APNG showed no posterization across the sky, where the GIF version dithered the same gradient into visible grain.

Does the APNG keep the raw editing latitude of a CR3?

No. A CR3 is a digital negative holding 12-to-14-bit linear sensor data with adjustable white balance and exposure; APNG is an 8-bit display format. Converting bakes in the current rendering, so do your white-balance and exposure edits first, then export. Keep the original CR3 files as your master — see the full CR3 converter for other export targets.

Will my APNG have transparent areas?

Only if you build them. A rendered CR3 frame is fully opaque — raw photos have no alpha channel, so there is nothing transparent to carry over. APNG supports 8-bit alpha, but this tool fills each frame edge-to-edge from the photo, so the output is a solid rectangle unless your source frames already contain transparency.

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 old browser that does not support it, the file falls back to showing its first frame as a normal still PNG, so it never appears broken. For a single still instead of an animation, use CR3 to PNG.
