So, for example, the program will allow you to resize a large group of photos to give them all the same format, rotate a series of vertical photographs to make them horizontal, or rename all of the files in a folder so that they have the same string of text in their names.
In addition, of course, you can change the format of the selected files, choosing from the most popular formats (JPG, PNG, BMP, GIF, PDF, TIFF...), crop images, and even apply certain effects such as gray scale, blur, red-eye correction, and many more.
The program interface was specifically designed to make it very comfortable to work with. Converting dozens of photos to the format that you want is as easy as selecting all of them and clicking. And there are definitely more than just a few supported files: BMP, JPG, GIF, TIFF, TGA, PNG, ICO, PDF, PDF/A, PSD, WMF, EMF, JBIG, JBIG2, WBMP, PICT, PCT, JNG, JPEG 2000, PIC, ICB, VDA, VST, PDD, WAP, WBM, EXR, PNM, PBM, PGM, PPM, XPM, CUR, CUT, DDS, DIB, FAX, HDR, IFF, BIE, JBG, JB2, JIF, KOA, LBM, MNG, PCD, PCX, PFM, PGM, RAS, SGI, RLE, XBM, EXIF, JTIF.
Photopus is a very useful photo editing tool. And, while it has some shortcomings if you're just working with one or two photos, as soon as you start working with a group of photos at once the program really shines.
