Image File Formats – JPG, TIF, PNG, GIF
Which to use?
The most common image file formats, the most important for cameras, printing, scanning, and internet use, are JPG, TIF, PNG, and GIF.
Digital cameras and web pages normally use JPG files – because JPG heroically compresses the data to be very much smaller in the file. However JPG uses lossy compression to accomplish this, which is a downside. A smaller file, yes, there is nothing like JPG for small, but this is at the cost of image quality. This degree is selectable, to be lower quality smaller files, or to be higher quality larger files. JPG is rather unique in this regard, using lossy compression allowing very small files of lower quality, whereas almost any other file type is lossless (and larger). WeScanFiles.com uses JPG when small file size is more important than maximum image quality. But JPG is good enough in many cases, if we don’t overdo the compression. Perhaps good enough for some uses. If maximum quality for archiving your important images is your goal, then you do need to consider a couple things:
- JPG should always choose higher Quality and a larger file, and
- Continue editing and saving your JPG images repeatedly causes quality lost every time you save it as JPG
