Version 3.0

(november 2025)

Download JimgBatchEn.zip (64-bit)

JimgBatch is a program with two functions:

Convert and/or resize set of image files to a unique format.
After the conversion is made, you may reorganize the list of resulting images using drag-drop, and renumber them with a unique name, to create a consistent set of images.
The program can read most usual image formats (Gif, Jpeg, Jpg2K, Png, Psd, Tiff, Raw, Webp). But it is not a paint program, so the settings included are elementary (orientation, jpeg quality...)
The Rename/Renumber tab may be used indepently to reorder, rename and renumber a set of files in a folder. Filters may be used on file names.

JimgBatch uses the FreeImage library for conversions.

Download and install

Download the ZIP file to a folder of your choice and unzip it.

By default, the application unzips to a subfolder JimgBatchEn.

Run JimgBatch.exe in the installation folder.

You may go to step 2 directly if you simply want to rename and reorder a set of files in a folder.

Select an original folder and a different destination folder. As an option you may add a filter for the file names.

In the right panel, choose the origin and destination file formats.

Convert to: 4 formats are available (JPG, PNG, TIFF, WEBP)

Grayscale: to convert images to B/W

Delete matadata: clears the metadata in the picture files.

Jpeg quality: Sets the quality of a JPG conversion

RAW : Changes default brightness for RAW images.

Resize: Check to resize the converted images and set a pixel size and resizing options:

Select an image to see preview. You may change the orientation of an image. It is memorized for conversion.

Colors in the list signal incorrect images or duplicate names of different formats that create conflicts.

Use the Del. key to remove unwanted images from the list.

'Replace files': uncheck this to skip conversion when a file with the same name is present in the destination folder.

'Convert image': Converts the selected image, for instance to check a result or a specific need.

'Convert all': Starts the conversion of all images.

A log file is created to check potential errors.

Once the conversion is completed, the second tab presents the list of converted files in the resulting folder.

(If you skipped Step 1, you may select a folder name and as an option, and add filters on file names and types.)

You may then reorder the images in the order you want by drag drop before renumbering.

New name: Set a unique name for the set.

digits number: sets a number of digits in the number (with leading zeros)

Start n°: Numbering start at 1 by default. You may set a number of your choice.

Colors shows if there is a potential conflict in renumbering the files.

Renumber: Sends the renaming of the list.

You may add or change the extensions associated to an image format. Please note that no checks are made on the extension validity.

You may also change the colors for errors.
