Note

• Supported input filetypes: JPG JPEG PNG WEBP BMP TIF TIFF

💡 Settings Explained

• Resize to:

  • Resolution: Resize to a specific width and height, ignoring aspect ratio.
  • Percentage: Resize the image on a percent scale.
  • Width: Target the image width and resize it.
  • Height: Target the image height and resize it.
  • Shorter side: Target the shorter side of the image and resize it.
  • Longer side: Target the longer side of the image and resize it.

• Condition:

  • Upscale and Downscale: Resize the image to the new dimensions, regardless of whether they're larger or smaller than the original dimensions.
  • Upscale Only: Resize the image if the new dimensions are larger than the original dimensions.
  • Downscale Only: Resize the image if the new dimensions are smaller than the original dimensions.

• Checkbuttons:

  • Use Output Folder: When enabled, a new folder will be created in the image directory called 'Resize Output' where images will be saved.
  • Overwrite Files: When disabled, conflicting files will have a _# appended to the filename. If enabled, files with the same basename will be overwritten.
  • Save PNG Info: When enabled, this option will automatically save any PNG/WEBP chunk info to the resized output if saving as PNG or WEBP. If converting from PNG/WEBP to another type, then a text file will be created containing the metadata.
    • Handling WEBP metadata requires ExifTool.exe to be in the same folder as this application.
    • ExifTool (2003-2024) was created by Phil Harvey and can be downloaded from https://exiftool.org/

• Filetype:

  • Select 'AUTO' to output with the same filetype as the input image. Alternatively, choose a specific filetype to force all images to be saved with the chosen type.

• Quality:

  • Used to control the output quality of JPG and WEBP images. A higher value results in a higher quality output. (Ignored for PNG)
