How to use Convert JPEGs to Animated PNG
- 1. Add your JPEG frames. Drop two or more JPEG photos into the file queue in the order you want them to play. Each JPEG becomes one frame of the resulting animation, so arrange them like a filmstrip.
- 2. Set the frame delay. Enter a value in Frame delay (ms) to control how long each frame stays on screen before the next one appears. Lower numbers feel like a fast flip-book, higher numbers read more like a slideshow.
- 3. Download the animated PNG. Click generate and download animation.png. The APNG cycles through your JPEGs losslessly, so it works anywhere APNG is supported without the color banding a GIF palette would introduce.
When to use Convert JPEGs to Animated PNG
Convert JPEGs to Animated PNG turns a folder of still JPEG photos into a single looping APNG file. It is useful whenever you have a short sequence of frames, like a burst of camera shots, and want them to play back as one image instead of juggling separate files.
- Before-and-after photo comparisons. You shot a before and after pair, or several progress photos of a renovation, and want them to flip automatically in a blog post instead of forcing readers to click through a gallery.
- Stop-motion from a phone burst. A burst-mode sequence of JPEGs from a phone camera becomes a tiny stop-motion loop, useful for a product page or a README that needs motion without embedding a video file.
- Preserving quality over GIF. GIF's 256-color palette introduces banding on photographic gradients. Bundling the same JPEGs as an APNG keeps full color depth, which matters for skies, skin tones and smooth shadows.
