The PNG format maintains the resolution... Myth or reality?

Is it true that the PNG format maintains the resolution?

Surely when saving an image someone will have suggested that you save it in PNG format, because, according to them, the PNG format maintains the resolution of an image better, but is that true? In this article we will seek to clarify this point.

The name PNG, comes from the English Portable Network Graphics, and refers to an image format that allows lossless data compression. This PNG format was developed as an improved replacement for the Graphics Interchange Format (GIF).

This PNG image format supports palette-based images (using 24-bit RGB or 32-bit RGBA color palettes), grayscale images, and non-palette-based full-color RGB or RGBA images. PNG's developers focused on designing the format for transferring images on the Internet, but not for printed graphics; therefore, color codes other than RGB are not supported. A PNG file contains a single image in a repeating structure of chunks, encoding the basic pixels and other information such as textual comments and integrity checks documented in RFC 2083.

Saving a graphic file in PNG format uses the .PNG or .png file extension

Conclusion

In conclusion, yes, PNG files enjoy lossless compression. This means that no data is lost when the image is compressed: the quality remains the same no matter how many times you edit and save the file. The image will not become blurry or distorted, making PNGs ideal for sharp logos and graphics that contain lots of shapes and details.
