File format information for PNM and JPG

Full NamePortable anymap
Mime Typeapplication/octet-stream

A PNM file, which stands for Portable Any Map, is a common file format used in computer graphics and image processing. It's a simple and versatile format that can store images in a raw, uncompressed form, making it easy to work with programmatically. PNM files are commonly used for tasks such as image manipulation, image conversion, and data exchange between different software applications. One of the key advantages of PNM files is their platform independence, as they can be read and written by a wide range of software on various operating systems.

PNM files come in three main variants: PBM (Portable Bitmap), PGM (Portable Graymap), and PPM (Portable Pixmap). PBM files represent binary images, where each pixel is either black or white. PGM files store grayscale images, allowing for various shades of gray. PPM files, on the other hand, support full-color images by representing each pixel with red, green, and blue color components. These variants provide flexibility for handling different types of images, from simple line drawings to high-quality photographs.

While PNM files have the advantage of simplicity and compatibility, they are not suitable for efficient storage of large, high-resolution images due to their lack of compression. In such cases, other formats like JPEG or PNG are preferred. Nonetheless, PNM files remain valuable in scenarios where simplicity, ease of processing, and compatibility are more important than file size efficiency, such as in certain image processing tasks or as an intermediary format during image conversion.

Full NameJoint Photographic Experts Group
Mime Typeimage/jpeg
Opens WithPaint.Net, Photoshop

A JPG file, short for Joint Photographic Experts Group, is a widely-used image file format known for its efficient compression and high-quality display of photographs and other complex images. It utilizes lossy compression, meaning some image data is discarded to reduce file size. This compression technique allows for smaller file sizes, making JPGs ideal for storing and sharing images on the internet and digital devices without compromising visual quality significantly. However, it's important to note that excessive compression can lead to noticeable image degradation, known as artifacts, especially in images with fine details or high contrast areas.

JPG files are commonly used in various applications, including web design, digital photography, social media, and document imaging. Due to their compressed nature, they are easy to upload, download, and display, making them a popular choice for online platforms where quick loading times are essential. It's worth mentioning that while JPG is excellent for photographs and natural scenes, it may not be the best choice for images with sharp lines, text, or simple graphics, as these can suffer from compression artifacts. For such scenarios, other formats like PNG or GIF may be more suitable.

Despite its widespread usage, it's essential to be mindful of multiple saves and edits on JPG files, as each compression can introduce additional loss of image data, leading to a gradual decline in quality known as generational loss. To preserve the highest quality, it is advisable to work with images in lossless formats or save a copy in an uncompressed format before converting it to JPG for final distribution or display.
