Supports: JPG, JPEG, JFIF
A JFIF file is just a JPEG — the same lossy, full-color, opaque photo data, wrapped with the standard JPEG File Interchange Format header. On its own a JFIF holds a single still frame, so this tool works as an APNG maker: upload several JFIF images and they are stacked in order into one animated PNG, each photo becoming a frame. Upload a single JFIF and you get a clean one-frame APNG. Unlike GIF, APNG keeps the full 24-bit color your JFIF photos already carry, so gradients and skin tones stay smooth instead of being crushed to a 256-color palette.
.jfif images (.jpg and .jpeg are accepted too). The order you add them is the order they play, so add the frames in sequence.| Property | APNG | GIF |
|---|---|---|
| Color depth | 16.7 million colors (24-bit RGB) | 256 colors per frame (8-bit palette) |
| Best for | Photographic frames, gradients, soft detail | Flat-color, simple cartoon-style loops |
| Compression | PNG DEFLATE, lossless | LZW, palette-based |
| Transparency | 8-bit alpha (smooth) | 1-bit (hard on/off) |
| Typical file size from photos | Larger, but no color banding | Smaller, but visible dithering/banding |
| Browser support | ~94.7% — Chrome 59+, Firefox 3+, Safari 8+, Edge 79+, Opera 46+; not Internet Explorer | Universal |
| Fallback if unsupported | Shows the first frame as a static PNG | n/a |
For photo sequences APNG is the better choice because your JFIF frames are already full color — GIF would throw most of those colors away. If you need an animation that plays literally everywhere, build a JFIF to GIF instead and accept the 256-color limit.
Not by itself. A JFIF holds one still frame, so converting a single file produces a valid one-frame APNG — a static image in an animated container, which won't appear to move. To get actual motion you need a sequence: upload several JFIF photos and they are combined into multiple frames, one per image. If your goal is a moving animation, gather the individual frames first (for example, a burst of photos or a numbered image series) and add them all in the order you want them to play.
They play in the order you add them. The first file you upload becomes frame one, the next becomes frame two, and so on. If the sequence looks out of order, remove the files and re-add them in the right order, or rename them with leading numbers (01, 02, 03…) before uploading so the order is unambiguous. Every frame shares the same FRAMERATE, so each photo is shown for the same length of time.
The conversion to APNG is lossless, so it adds no new compression artifacts — but it can't recover detail the JFIF already discarded. JFIF is a JPEG, which is lossy, so each source frame already has whatever compression the original encoder applied baked in. APNG faithfully preserves what's there in full 24-bit color and stops further degradation. In our testing, a sequence of five 1080p JFIF photos at default quality produced a sharp, banding-free APNG; the main tradeoff is file size, since lossless full-color frames are heavier than the equivalent GIF.
Photographic APNGs can get large because every frame stores full lossless color. Three levers help: lower the FRAMERATE so fewer frames are needed for the same duration, drop the resolution with a preset or a resize percentage, and switch Colors to "By Color Reduction + Dither" to shrink the palette. Each one trades a little fidelity for a smaller file. If the result is still too big after converting, run it through compress APNG to squeeze it further without changing the format.
APNG plays in roughly 94.7% of browsers worldwide: Chrome 59+, Firefox 3+, Safari 8+, Edge 79+, and Opera 46+, on both desktop and mobile. Internet Explorer never supported it. In any viewer that doesn't understand the animation chunks, the first frame shows as a normal static PNG, so the image is never broken — it just doesn't move. If you need guaranteed motion everywhere, including very old clients, keep a JFIF to GIF copy as well, or convert the finished animation with APNG to GIF.
