Converting or resize multiple images takes a lot of time if you're using an image editor. As a workaround you should try a batch image processing software. We have reviewed our fair share of batch processing applications for Windows, including ImBatch, ImagesMixer, XnResize or Pictor.
Photo Resizer Expert is a freeware tool that can batch resize, convert, watermark, crop images and a lot more.
The installer has an option to add the program to the Windows Explorer context menu, you can uncheck the box to prevent it from being added.
A splash screen is displayed when you run the program, click on the continue button after 5 seconds to access the software. It tells you that it is a free trial and that you can use it for 100,000 days. That's over 273 years in case you were wondering. Jokes aside, that's Photo Resizer Expert's way of saying that it is free for noncommercial use.
Click on the Add files button on the toolbar to add some images for editing. You may drag and drop files onto the UI. If you allowed the Explorer shell integration, you can use the context menu to open the selected files in Photo Resizer Expert. Want to batch edit all images in a directory? That's what the add folder button is for. The program can open virtually all image formats including raster, RAW, PSD (Photoshop) formats.
The program lists the images in the top pane, and the columns indicate the filename, size (in KB), date and the full path of each file. Save the list of files to a text document from the file menu, in case you want to come back later, the Import List option can be used to add the files from the saved list.
Select an image and it is displayed in the preview pane on the right-hand side. The picture's original size (resolution in pixels) is mentioned below the preview, and this helps in determining the output size. The preview also tells you the total size of the selected images. Hit the "Show Resize Preview" button and a new window opens, it allows you to view what the output file will look like. Use it to decide whether the image is alright, or make adjustments as required.
The pane at the bottom of Photo Resizer Expert's interface has several tabs. You may choose the image editing profile to use preset options, or customize the settings and save it as a custom profile.
Define the resolution of the output images using the Image size tab. It lets you set the width and height in Pixels, Percentage, Inches, Centimeters, Millimeters and Points. The aspect ratio setting when enabled preserves the ratio of the original picture.
Next is the Image Format tab, and you can use it to select the output format that the pictures should be saved in. Photo Resizer Expert can save images in the following formats: PNG, JPG, JPEG, BMP, GIF and TIFF. Saving the image in JPEG? The JPEG quality slider lets you restrict the file size as required.
Choose the Output Folder where the processed images should be stored in. If you added folders and sub-folders, the program preserves the folder structure of the source directories.
