Chances are good that you’ve witnessed a wide variety of file formats flit across your screen, but do you really understand what they mean? For example, you may understand that a JPEG is for pictures but what’s a PNG and a TIFF?

And which format supports an image with a see-through background? In this column, you’ll get answers to those questions and more. JPEG stands for the Joint Photographic Experts Group that developed it. It supports a wide range of colors, so it’s the one most folks capture on their cameras and (JPEG works well for black-and-white photos, too). However, JPEGs are also compressed, so some detail gets sacrificed to produce a smaller file size, which is great for maximizing space on your camera’s memory card, posting online, or for sharing via email. Happily, apps that let you save files as a JPEG also let you specify quality level, so you can control how much detail is lost. In fact, a JPEG saved at the highest quality from your scanner is indistinguishable from a TIFF.

May 08, 2017  The M4V file format is a video container format developed by Apple and is very similar to the MP4 format. The primary difference is that M4V files may optionally be protected by DRM copy protection. Apple uses M4V to encode video files, such as TV episodes, movies, and music videos, in its iTunes Store. What Is the Best Video Format for Mac OS X. To be frank, knowing the best format for playing, editing, uploading is just in the infancy of manipulating video performance.

It’s also practically impossible to spot quality loss on a second generation JPEG—say, you edit the original JPEG (1st gen) your camera or scanner captured and then save it as a JPEG (2nd gen) at the highest quality—which is why it’s the preferred format for uploading to online printing services and stock photography agencies. However, if you open JPEG (2nd gen), edit it and then save it as a JPEG (3rd gen), you’re well on your way to creating pixel pudding. To avoid this in apps such as Adobe Photoshop, the Photoshop Elements Editor, Affinity Photo, or Pixelmator, save JPEG (1) in the app’s native file format (say, PSD) to preserve quality. To re-edit the file, open the PSD, make your changes and then save a JPEG from the native file. You don’t have to worry this in apps such as Apple Photos, Adobe Photoshop Lightroom, and Alien Skin Exposure X. In these database-driven apps, you’re always working with the original—your edits are stored in a database and applied when you export the image, which generates a new copy. TIFF stands for tagged image file format and it’s long been the gold standard for printing high-quality images.
