Convert multiple .jpg files to .bmp files

Question

I am currently making a game with iGraphics, and for that I have to use images only in .bmp format. I have multiple .jpg images, and I want to convert all of them to .bmp format. Just changing the extension didn't work for me, I have to open each image in MS paint and then save that image as .bmp format. I have to do this for all the images one by one. Is there any way to convert all of them at once?

Answer 1

I have multiple .jpg images and I want to convert all of them to .bmp format.

One possible solution is to use ImageMagick. ImageMagick is a free, open-source cross-platform command line tool for image manipulation. You can download a copy here.

After installing ImageMagick, you can add magick.exe to your Windows path and use the following in a command window (wherever your images are stored):

magick mogrify -format bmp *.jpg

If you don't wish to add magick.exe to your path, you can always specify its full path instead.

Answer 2

While i prefer using magick (like the other poster), before i started using commandline tools i used irfanview for the same thing.

I think it uses magick in background, but gives a nice gui.

Copied from here.

It's not my own solution, but its copied from my bookmarks, from what i used for the same/similar things.

Instructions

Open Irfanview, and click on File, in the Toolbar, and select Batch Conversion/Rename.... This will open the Batch conversion dialog box.

In the Look in: box, navigate to the images you want to convert.

Select (single Left click) the images to be converted, then click the Add button. This will add the selected file to the Input files: box, to the left of the Add button.

Next, you need to decide where you want the files to be placed, after converting. If you want the images to be placed in the same folder you loaded them from, click the Use this directory as output button.

If you want to put them in a different folder, under Output directory:, click the Browse button, and navigate to where you want them placed. Under Work as:, select Batch conversion.

Under Batch conversion settings, use the drop down arrow to select the Output format. If you don't want to change the file format (jpeg, gif, bmp, etc.), just select the format the images are already in.

Use the Options button to change the image quality. The format you use, will determine if the Options button is active, or not.

This will bring you back to the Batch conversion dialog box.
