The Digital Initiatives department is all for low-cost options when it comes to software.

Software for digitization projects or digital collection management can get expensive, particularly when you need multiple programs for different purposes (editing, converting, renaming, etc.) and formats (images, documents, video, audio, OCR, etc.). Did I mention it’s free? I probably should have led with that.įor information on additional software that Digital Initiatives recommends, consult the Hardware & Software page on LibGuides. Nicely done, Bad Peggy! If you use JPEGs (or PNGs) and you want to keep an eye on them for long-term storage, Bad Peggy is a great option. The program detected the issue right away. I corrupted a copy of a JPEG with the website and then used Bad Peggy. ALWAYS make a copy to play around with.īack to the experiment. Of course, NEVER run tests like this on the original file. Although I do not support the reasons the website mentions for corrupting files, it was a rather useful site for my test.
Believe it or not, there are websites that will corrupt files for you. Bad Peggy quickly scans images (or entire folders of images) and checks for irregularities, such as corruption.Īlthough Bag Peggy has been tested and authenticated by others, I wanted to do a test for myself.
There are no confusing settings or add-ons. One of the best things about Bad Peggy is its simplicity. This is why Bad Peggy can be useful for both institutions and citizens since both will likely use JPEG extensively. In the digital preservation world, JPEG is not a preferred format for originals because of its data loss (see NDSL’s “ Digitization Standards”), but JPEG is still widely used. The reason for the small file size, however, is the lossy compression process associated with the format ( see the “JPG vs. JPEGs typically have manageable file sizes which makes them easy to share, email, upload, etc. JPEG (or JPG) is an abbreviation for Joint Photographic Experts Group. It enables you to find such broken files quickly, inspect and then either delete or move them to a different location.” The name and logo are certainly intriguing.Īccording to the Community Owned digital Preservation Tool Registry (COPTR), which is a fantastic resource, Bad Peggy “scans images (JPEG, PNG, BMP, GIF) for damages and other blemishes, and shows the results and files instantly. I also wish I knew more about the program’s logo/ icon (a corrupt image of a foot in high heels that is turned sideways). I wish I knew more about the origin of the name.
One program specifically designed for JPEG, PNG, and GIF caught my eye. There are many available, and most of them focus on certain formats (TIFF, PDF, JPEG, etc.). I recently spent time researching and testing various validation programs. This type of software supports the validation of digital files by scanning specific file formats for errors, data loss, corruption, etc. Useful image editors, converters, and renamers have already been covered ( GIMP, XnConvert, and Advanced Renamer). For this month’s column, we turn our attention back to software.
