![]() ![]() ![]() But can I be honest? I'd do that with a more efficient and far faster conversion utility like IrfanView. Photoshop is incredibly slow for this type of work. For example, I did a quick test to demonstrate the difference in performance:įolder with 10 images in jpg format, 5600px by 5600px. 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. Above command works for command line, if you plan to use the command inside a batch file (. 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. svg files in your sub-directories under the root folder you launched your command from.

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. While you can batch convert and export HEIC files to JPEG in Preview. 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. According to this comment on an issue report on the ImageMagick repo it turns out. 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 record an action in photoshop to convert. This takes about 33 seconds compression time per image with my benchmark images. eps files in a folder, and use the Photoshop image processor to change them to. It also explains why IrfanView is so much faster and still produces nicely compressed versions. ImageMagick Recursive Powershell Script with Progress display This script will execute a command recursively on all folders and subfolders This script will display the filename of every file processed set the source folder for the images srcfolder 'C:\temp' set the destination folder for the images destfolder 'C:\temp' set the ImageMagick command imconvertexe 'magick' set the source image format (wildcard must be specified) srcfilter '.png' set the destination (output.
