In IrfanView and ImageMagick we can control the quality setting from 0 (uncompressed) up to 9 (max compression). It also explains why IrfanView is so much faster and still produces nicely compressed versions. This takes about 33 seconds compression time per image with my benchmark images. Next, I checked the "save for web" option - which resulted in the long wait times again, because it seems PS automatically sets the compression rate to one of the highest (8 or 9). Then, however, I noticed the reason for this: no compression is applied at all by PS, and the resulting PNG files are huge, this being the nature of uncompressed PNGs. I ran RB's image processor on the same list of images as before, and was surprised to see it converted all the JPGs to PNGs in a matter of ~10 seconds. But it is much slower than IrfanView, a tad faster than PS.Īfter some more testing I have to partially retract the words I have written above. It is a command line tool, and easy to use for conversions.Will also work on a mac.

ImageMagick is also free and open source. The batch processing you can find under File->Batch Conversion

This matters if you have hundreds of images to convert.ītw, Irfanview (windows only) is free to download It's too slow.Īnother issue is that during the conversion process Photoshop cannot be used - while with a simple conversion utility you can leave it running in the background, and continue to use PS for other work if required. That's a rather big difference - and with large numbers of images I just do not have the time to wait for Photoshop to finish the job. For example, I did a quick test to demonstrate the difference in performance:įolder with 10 images in jpg format, 5600px by 5600px. Photoshop is incredibly slow for this type of work. Unless you can find a good copy of any corrupt file from a backup, there probably isn’t much you can do about these (trying to fix the image header with a hex editor to retrieve a corrupted image usually isn’t worth the effort).But can I be honest? I'd do that with a more efficient and far faster conversion utility like IrfanView. Depending on which conversion utility you use, it may stop if it encounters a corrupt file or may just log the problem and carry on converting. Inspect a few sample images to see how much bigger or smaller the converted files are than the originals, and then use that ratio to estimate how much extra storage space you’ll need. If you have tens of thousands of old PCX files you may need to leave the batch conversion running overnight, but so long as you don’t run out of disk space you’re unlikely to have any problems. Most batch converters will happily search down through subfolders to find images to convert, and put the converted files alongside the original image or in another folder if you’d prefer.

Once you’ve converted all your PCX files, which takes only a few seconds per file, you can archive all the original PCX files to CD or DVD and then use the PNG files in their place. Commercial users should buy a licence for €10 per user, but there are discounts available for bulk purchases. There are many packages that can do this for you: IrfanView is one possibility that’s free for non-commercial use. Most image-editing packages that can read PCX files can write PNG and so are able to convert files from one format to the other, but if you have many files in the old format you’ll probably want to use a batch conversion routine to convert all the files in one operation. PNG is now the best lossless image format available for most applications, and is the default format used internally by Microsoft Office applications. The only feature PNG lacks compared to GIF is the ability to animate images. The PNG format was designed to replace GIF, and it has much greater colour depth (16 million colours), better transparency support (an 8-bit alpha channel, where GIF has only a single-bit alpha channel) and more efficient compression than GIF. It was also hobbled because for ten years (1994-2004) Unisys insisted that anyone who supported it within their application had to pay a licence fee to use the LZW (Lempel–Ziv–Welch) compression algorithm on which it relied. It was invented back in 1987 and so is stuck with a palette of just 256 colours. GIF is another possible format to consider but it, too, is both old-fashioned and restrictive.
