Why are PNGs so small?
2 Answers. PNG is a lossless format and compresses the image data by first performing a step called prediction and then applying the same algorithm used in zlib. The prediction step is a crucial one in order to effectively compress the file, and it is based on the values of earlier neighbors pixels.
Can PNG files have motion?
Motion can handle 32-bit transparent PNG files (and sequences).
How much can you compress a PNG file?
To reduce the size of PNG files the software reduces the number of colours in a PNG image, which allows it to convert the 24-bit PNG to a much smaller, more efficient 8-bit indexed color image. The file size reduction can often be as much as 60-80% smaller than equivalent 24/32-bit PNG files.

Is it safe to reduce the size of an image?
You’ll be able to control the image quality, which comes in handy when you want your finished product to look polished and professional. It’s usually pretty safe to scale down an image. When you make it smaller, it typically still looks good. It has all the pixels (tiny dots of color) it needs, it’s just being condensed.
Is it OK to expand an image to 72 dpi?
If you don’t have enough pixels per inch, your enlarged image will look fuzzy or choppy. Check the resolution to see how much you can safely expand your image. Whereas 72 dpi doesn’t give you much room to expand, 300 dpi does, especially if you ever want to print your image.
