Need help?Convert JPG to APNG Online
Turn a set of JPG photos into one animated PNG: upload your JPEG frames in order, set a frame rate, and download a single looping APNG. Unlike GIF, APNG keeps full 24-bit color, so photographic frames stay smooth and banding-free instead of being crushed to a 256-color palette. Upload one image and you get a clean one-frame APNG; upload several and each becomes a frame in the animation.
How to Convert JPG to APNG
- Upload Your JPG Files: Drag and drop or click "Add Files" to add your JPEG photos. They become frames in the order you add them, so arrange them before converting (JPG, JPEG, and JFIF inputs are accepted).
- Set the Frame Rate: Pick a value from the FPS dropdown — 10 FPS (Recommended) for a typical loop, or 1 FPS (Slideshow) up to 50 FPS to speed it up or slow it down.
- Adjust Image Quality or Resolution (Optional): Use Image Quality (%) to trade detail for a smaller file, or set a Preset Resolution / Width x Height to resize every frame.
- 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.

Frequently Asked Questions
How do I combine multiple JPGs into one animated APNG?
Add every JPG you want as a frame before you convert — the upload order is the playback order. Each image becomes one frame, and the FPS setting controls how long each frame is shown. A single uploaded image produces a valid one-frame (static) APNG.
Why pick APNG over GIF for photos?
JPG photos are full-color, and GIF caps every frame at 256 colors, which adds visible banding to skies, skin tones, and gradients. APNG stores full 24-bit color losslessly, so the frames look like the originals. In our testing, a 3-frame 1080p JPG sequence produced an APNG with no posterization, where the GIF version showed dithering across smooth areas.
Will my APNG have transparent areas?
No. JPG has no alpha channel, so every frame is fully opaque — there is nothing transparent to carry over. APNG's 8-bit alpha only helps when the source already has transparency. If you need transparent frames, start from PNG instead with PNG to APNG.
Does converting to APNG lose quality?
The APNG container is lossless, so it does not re-compress your frames the way GIF's palette reduction does. Your frames still carry whatever quality the original JPGs had — JPG is a lossy format, so the APNG preserves that existing detail without adding new loss unless you lower the Image Quality (%) slider.
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 (such as Internet Explorer), the file falls back to showing its first frame as a normal still PNG.
