While most users won’t mind having a few broken images sitting on their hard drive, others may want to find the broken images to delete or move them. This can for instance be handy if they regularly watch image slideshows on their computer, as broken images might return error messages, break the slideshow or return an empty screen.

Bad Peggy is a Java application that can be used to scan a folder for broken or defect jpeg images. The program will automatically scan all jpg compatible image formats in the root folder and all of its sub-folders.

You select the root folder with a click on File > Scan or the keyboard shortcut Ctrl-s. The program will then scan all jpg files in the folder structure.

All broken or defective images are listed with their file name, path and reason why they have been added to the listing.

This can be the reason if a file is not a jpg image but has the jpg extension, or if it is a truncated file. Images can be selected with the left mouse button. The program tries to display a preview of the image on the left side of the screen. This works well for some types of errors, for instance if the file is truncated, which often is caused by a transfer error. Other jpg images may show a blank screen instead.

A right-click opens a context menu with options to delete or move the file. It is additionally possible to export the list of damaged jpg images.

Additional file types to scan can be added via Options > File Extensions. The application cannot scan large jpg images. It displayed error messages when I tried to scan a folder containing digital camera image with a size of three and more Megabytes.

Bad Peggy is compatible with the Windows and Linux operating system. The software can be downloaded from the developer website.

PDF is the most popular format for digital archiving in the world. Normally PDF files are created by virtual printer; however it is not easy to create PDF documents from multiple scanned images. JPG To PDF Converter is a windows application that quickly converts multiple images into a single PDF document without virtual printing.

JPG to PDF Converter supports the majority of modern graphic formats, including GIF, BMP, TIF, PNG, JPG, ICO and PSD. Users can control the compression ratio of PDF files for optimal quality/size balance and specify such PDF file properties as title, creation date, subject and keywords.

Many people like to scan in documents such as official personal or business paperwork and household bills.  It’s annoying for people having to store these documents as JPG or other image files.

For anyone who wants to test the images in their browser, they are here and here. I was not able to come up with a solution yet, the second image was displaying fine after a few tries but it seems to be caught in an endless loading loop. The image is displayed completely but the loading bar is still loading something, not sure what it is. Saving the images and viewing them in Windows turns out to be working correctly.

A quick research seems to suggest that those images have been saved using CMYK encoding and not the usual RGB encoding. It turns out that Firefox is having problems displaying images that have been encoded this way and cannot display them properly, hence the error message The image [...] cannot be displayed, because it contains errors when trying to load such an image.
