How To Export and Save Images in PNG File Format in GIMP Editor

GIMP (GNU Image Manipulation Program) is a free and open-source raster graphics editor used for image retouching and editing, free-form drawing, image conversion between different formats, and more.

Why Use the PNG File Format

The PNG (Portable Network Graphics) file format is a popular lossless image format well-suited for editing and sharing digital images. Here are some of its key advantages:

  • Lossless compression: PNG uses lossless data compression, meaning no image quality is lost when saving images. This makes it ideal for editing images multiple times without degradation.
  • Transparency support: PNGs allow transparency, making them perfect for images with irregular shapes and transparent backgrounds. This is especially useful for graphics, logos, icons, etc.
  • Web compatibility: PNG is well supported by all modern web browsers, making it a reliable format for website images.
  • Metadata support: You can embed color profiles, captions, copyright info and more metadata within PNGs.

Exporting Images as PNGs in GIMP

Follow these simple steps to export images as high-quality PNG files in GIMP:

  1. Open the image file in GIMP that you want to export as a PNG.
  2. Go to File > Export As or use the keyboard shortcut Shift + Ctrl + E (Windows/Linux) or Shift + Command + E (macOS).
  3. In the export dialog box, locate the Select File Type option at the bottom and choose PNG image from the dropdown menu.
  4. Enter the filename for your PNG image and select the folder location you want to export it to.
  5. Click Export to open the “Export Image as PNG” dialog box.
  6. Adjust any PNG configuration options if desired, like enabling interlacing for progressive display. The default settings typically work fine for most purposes.
  7. Click Export again to finalize the PNG image export.

And that’s it! The image will now be exported and saved as a PNG file in the chosen folder location.

Recommended PNG Configuration Settings

When exporting PNG files in GIMP, you have various configuration options available to customize your exported PNG:

  • Interlace: Enabling this displays the PNG progressively when loading on web pages.
  • Save background color: Includes transparency in PNGs. Disable to export JPEGs with white backgrounds instead.
  • Save gamma: Helps browsers better display colors if using gAMA chunk.
  • Save metadata: Embeds color profiles, creation timestamps, comments, etc. Disable to omit metadata.
  • Compression level: Higher levels create smaller files but take longer to compress. Level 9 is best for maximum, lossless compression.

For most purposes, the default export settings provide a good balance. But you can tweak specific options based on your unique needs and image requirements.

Batch Exporting Multiple Images as PNG

If you need to export multiple images as PNG files, GIMP provides batch processing capabilities to automate this:

  1. Go to Filters > Batch > Batch Process.
  2. Click Add and select all the images you want to batch export.
  3. Set the Output location where exported PNGs will be saved.
  4. Enable the Use file extension option and enter “.png” to set PNG as the output format.
  5. Click Run to batch export all images as PNGs.

This saves the hassle of manually exporting images one by one.

Other Recommendations When Exporting PNGs

Here are some other tips for successfully exporting high-quality PNG images within GIMP:

  • Export layers as separate PNGs if transparency is needed, since flattening combines visible layers.
  • Avoid extreme PNG compression levels to prevent introducing compression artifacts.
  • Export important metadata like color spaces, copyright notices, etc.
  • Enable interlacing for progressive rendering in web browsers.
  • Double check image dimensions if downscaling for web use.

Following these best practices will ensure you export pristine PNG images perfectly suited for your specific needs.

In summary, exporting images as PNG files using GIMP is straightforward – simply use the Export As dialog, choose the PNG file type, adjust any desired configuration settings, and export your image in this versatile lossless format.
