[peor]

I have a question about image quality becomes worse as I convert jpg to bitmap in Animate.

We eagerly anticipate the question.

BMP format files are uncompressed bitmapped images, while those with a JPG format are compressed digital images. BMP formatted images have a higher resolution than JPG images.  BMP images are larger in size when compared to JPG images.

So to answer your question you can't take a jpeg which is lower quality than bitmap and expect it to get better.  So... you can't take something with pixels that is small and make it big without it looking worse.

"BMP format files are uncompressed bitmapped images"

False. BMP files use RLE or Huffman compression.

"BMP formatted images have a higher resolution than JPG images."

Also false. BMPs and JPEGs can both be whatever resolution you want (up to the maximum resolution supported by each format, which is in the gigapixel range).
