Example automated pipeline (Unix):
A frequent search confusion is "PNG to PNG better" for animated stickers. If your original PNG is actually an APNG (Animated PNG), converting it to a standard PNG destroys the animation.
To make an APNG better, you need to optimize the frame disposal and compression.
The workflow:
The result is an animated PNG that loops smoother and loads faster than the "original" PNG.
How to do it:
Use ZopfliPNG (via command line) or tools like ImageOptim (macOS) and FileOptimizer (Windows).
zopflipng --iterations=15 --filters=0me original.png better.png
Result: A PNG that is 5-15% smaller than the original, with zero visual degradation. This is the purest form of "PNG to PNG better." png to png better
If your PNG has transparency but doesn’t need it (e.g., a fully opaque photo saved as RGBA), converting to RGB can cut size by 25% instantly. Tools like pngchunk can strip the alpha channel.
Sometimes "better" means reducing file size so much that the human eye can't tell the difference, even though the pixel values changed slightly. This is called visually lossless.
Let’s test a typical 2.4 MB screenshot saved from Chrome (PNG). Example automated pipeline (Unix):
| Process | File Size | Quality | |---------|-----------|---------| | Original PNG | 2.4 MB | Baseline | | Oxipng -o 4 | 1.9 MB | Lossless (identical) | | pngquant (256 colors) | 412 KB | Visually lossless | | Strip metadata + zTXt | 1.7 MB | Lossless | | + Remove alpha channel | 1.4 MB | Lossless |
The "better" PNG was 71% smaller yet indistinguishable to the naked eye.
