Name

Name

The Name field allows you to customize the filenames for your converted images.

By default, the image filenames match the original PDF filename. To change it, type your desired name into the text box.

You may use any letter or number in a filename, with the exception of the following special characters:

:;\\\[]{}—§…–/«»„”¿¡’′‰*

If you accidentally enter extra spaces or returns, KitBatch will automatically correct the error and format the filename properly.

Image filenames must be a minimum of 1, and a maximum of 30, characters in length.

If you erase the filename without entering a new filename, the previously saved filename will be used.

Custom filenames help organize your image exports and identify the PDF source.

Color & Size - Background

Color & Size
Background

The Background option appears if your PDF has transparency (an alpha channel).

It allows you to choose:

• Transparent - Keeps any transparent areas in the conversion
• Solid Fill - Fills transparent regions with a solid color

To retain the original transparency, ensure Background is set to "Transparent".

Choosing Solid Fill is useful if you want to remove transparency or need a specific background color.

Note: This option only appears if the Image Type is set to something other than JPG, since JPEGs do not support transparency.

If "Solid Fill" is chosen for the Background, the Background Color option appears.

To change the fill color:

1. Click the color box to open the color palette
2. Select your desired background color
3. Close the palette - your new color will be shown

The color palette provides a wide range of hues and tones to match your creative vision or brand style.

If you set a custom color but want to revert back to a transparent background:

1. Go back to the Background setting
2. Change the selection to "Transparent"

Background colors allow limitless customization for a polished, professional look.

Color

The Color option lets you choose between full color or grayscale conversion.

• Color - Keeps images in the original full color
• Grayscale - Converts images to grayscale

Use the picker to select whichever choice best fits your needs.

Color is ideal for maintaining the original vivid appearance. Grayscale creates a classic, monochromatic look.

If your PDF does not have any color, choose grayscale to maintain the original appearance.

The choice comes down to personal preference and which style aligns better with your project. Both produce professional, quality images from your PDFs.

Color & Size - Image DPI

Color & Size
Image DPI

DPI (Dots Per Inch) or resolution refers to the amount of information in an image. It controls print quality and image detail.

For images only being displayed on screens - Leave the DPI setting at 72. This is standard for web and digital use.

For images being printed - Increase the DPI to 300 or higher for best results. Consult your printer documentation to determine the maximum resolution it can effectively handle. Higher DPI equals greater print clarity and quality.

Changing the DPI also impacts the image dimensions in Pixels, Points, and Picas. This is because DPI directly relates to these measurements. However, width and height in Centimeters, Inches, Millimeters, or Percent remain constant if altering DPI. Those values represent physical print dimensions, which stay fixed as DPI changes.

If you enter a DPI value lower than 72, the Image DPI will remain unchanged, as will the width and height. If you start a batch, the previously set valid DPI will be used for that image. To confirm the active DPI, deselect and reselect the file to reload the last saved value.

Note: GIF images can only be exported at 72 DPI. If your Image DPI is set higher than 72 when you select GIF as the "Image Type", KitBatch will automatically change the DPI to 72, and the Image DPI field will disappear. This will recalculate the image dimensions to match the new 72 DPI resolution. Remember, you will only see the image dimensions change if your measurement type is Pixels, Points, or Picas.

You can customize the image dimensions using various measurement units, similar to photo editors like Adobe's Photoshop. However, KitBatch always maintains the original aspect ratio. Changing the width recalculates the height, and vice versa.

Measurement options:

• Percent - Scales based on original dimensions. Enter 200% to double image size.
• Pixels, Picas, Points - Dimensions grow with higher DPI.
• Centimeters, Inches, Millimeters - Physical print size remains constant at any DPI.

Be sure to enter values of at least 1 or images will revert to default sizing. 0 will not update the settings.

Precisely sizing outputs streamlines your workflow. Need social posts? Choose pixels. Print materials? Use Centimeters or Inches for real-world dimensions.

Page Range

Page Range

The Output option allows you to specify which pages are converted.

• All Pages - Converts every page in the PDF
• Single Page - Output just one selected page
• Page Range - Select a starting and ending page to output a custom sequential range

For Page Range, use the "From" and "To" fields to define the start and end of your range.

To output multiple non-consecutive sections, run each range as a separate batch.

Precisely choosing pages is an easy way to convert only the content you need.

Save Options - Image Type

Save Options
Image Type

KitBatch supports conversion to all major image formats, including:

• BMP - Bitmap
• GIF - Graphics Interchange Format
• JPG - JPEG
• JPG2000 - JPEG 2000
• PNG - Portable Network Graphics
• TIFF - Tagged Image File Format

Select the type that best fits your project needs using the picker. To output multiple formats per PDF, run separate batches.

Note: If your PDF has transparency and you want to use the Background options, you must select an image type other than JPG as it does not support an alpha channel.

Save Options - Filename Format

Save Options
Filename Format

The Filename Format option is especially useful for multi-page PDFs. It lets you define custom filename structures for your converted images.

The picker provides the formatting option choices.

Here's what the components represent:

• Filename - The base name you set for the images
• Page - Denotes the following number is the page
• 1 - The page number placeholder

For example:

• Filename_Page_1

Would output:

• Filename_Page_1
• Filename_Page_2

Choose the structure that best fits your workflow needs and naming conventions.

Save Options - Sequential Numbering

Save Options
Sequential Numbering

One of KitBatch's most powerful features is the ability to sequentially number images across multiple PDF files. This unifies exported images into an organized, cohesive set.

Sequential numbering works when:

• Multiple files have identical Name, Image Type, and Save Directory settings
• Sequential Numbering is enabled for those matching PDFs

With sequential numbering turned on, KitBatch will process the PDFs in the order in which they appear in the batch list, and number their pages consecutively from start to finish.

For example, if File 1 has 4 pages, and File 2 has 3 pages, with sequential numbering the image filenames would be:

• Filename_Page_1.jpg
• Filename_Page_2.jpg
• Filename_Page_3.jpg
• Filename_Page_4.jpg
• Filename_Page_5.jpg
• Filename_Page_6.jpg
• Filename_Page_7.jpg

The pages seamlessly combine into a single numbered sequence.

Note: Files must have sequential numbering enabled to be included in the sequence, even if they match the criteria. Non-sequential files will get (X) added to differentiate.

For instance, with 2 sequential and 2 non-sequential 2-page PDFs:

• Filename_Page_1.jpg
• Filename_Page_2.jpg
• Filename_Page_3.jpg
• Filename_Page_4.jpg
• Filename(1)_Page_1.jpg
• Filename(1)_Page_2.jpg
• Filename(2)_Page_1.jpg
• Filename(2)_Page_2.jpg

No limit exists on the number of non-sequential duplicates.

Note: Sequential numbering for a PDF file will be disabled if you modify a value that causes the file to no longer match the criteria for sequential numbering. Once disabled, the sequential numbering option will disappear for that file. To re-enable sequential numbering, you must first change the value back so the file matches the criteria again. Then, you will need to manually turn on sequential numbering for that file once more.

Save Options - Include Annotations

Save Options
Include Annotations

The Include Annotations option only appears if the selected PDF contains annotations (comments, notes, etc.) on any pages.

By default, it is enabled so all annotations are included, matching the original PDF.

To output clean images without annotations, simply disable this option.

It provides an easy way to strip out annotations when needed, while retaining the ability to preserve them by default.

This helps streamline your workflow by eliminating manual annotation removal when required. The choice comes down to whether annotations are valuable or undesirable for your use case.

Save Options - Save Directory

Save Options
Save Directory

Due to macOS’ file security restriction called sandboxing, KitBatch does not have automatic access to write files to your folders and must be granted explicit temporary access.

When KitBatch is first launched, your personal folders like Documents or Desktop are blocked for writing files until access is provided.

To grant KitBatch access to write your converted image files, you must actively click the folder icon to open a standard save dialog and choose an output directory.

Choosing a save directory in this way lifts the sandbox restrictions for your current session only. KitBatch is then able to write your converted images to your selected destination folder.

It is highly recommended to choose your desired output directory before each batch conversion, as attempting to start the process without an allowed save location will result in a dialog interrupting your workflow and pausing the batch until a folder is actively selected.

Actively granting temporary write access ensures uninterrupted batch processing and provides you full control over where your converted image files are saved.
