alterImage has been completely rewritten in Objective c and applescript. It is optimized for the fastest processing of images using The unix sips program built in to the OSX operating system.

You can contact support with questions or to report a bug or offer suggestions.


With alterImage you can, crop, scale, size, rotate, convert and rename a single image or a folder of images. It is fast, efficient and very useful for anyone who works with images. You can see the image in the info drawer on the left and any editing you have selected will show up in the image information listed there so you see what the resulting image will be


How To use alterImage

  1. Launch alterImage .
  2. Drag and drop an image or folder of images into the Source text field, or press the Source button to browse.
  3. iAlterImage will automatically create the default destination for the converted images. This will be the same folder that the image(s) reside in.
  4. If you want to choose a different destination, drag a folder into the Destination text field or press the Destination button.
  5. Check off any functions you want performed on the image(s).
  6. Select a different image format to convert to, if desired.
  7. Press the Proccess button.
  8. alterImage will process the images and placed the new ones in the destination folder.
  9. If you are processing multiple images and select to rename them, each additonal image will have a sequential number appeneded to its name in the destination folder.


The main settings window


The settings

  1. Scale: Will scale the image size proportionally without changing resolution.
  2. Size: Will reduce the longest side of the width or height to the desired length, maintaining overall proportions.
  3. Crop: Crops the image to the desired dimensions.
  4. Resolution: check the box and indicate what resolution you want the image changed to.
  5. Flip: Flips image.
  6. Rotate: Rotates image.
  7. Rename images: Will rename the images adding numbers after the name for multiples. Image, Image 1, Image 2, etc.
  8. Convert to: Converts an image into another format.
  9. Source: The source image or folder of images to edit.

Converting to different file formats

You can convert from any of the following file formats: jpeg, tif, png, psd, bmp, gif, tga, pdf, and icns.

You can convert To any of the following file formats: jpeg, tif, png, psd, bmp, gif, tga, and pdf.

NOTES: you can convert an icns ( icon file ) to a standard image format which is useful for working with icon images. Converting from a pdf file will create an image file from the first page of the pdf.



A note about scale, size, crop, and resolution:

Resampling and image size and pixels can be very confusing. I have set up these functions for a typical usage. alterImage uses the unix sips program to process images. The scale and size functions resample the image to the desired pixel dimensions. On the web image dimensions are usually seen in pixels though you can see the final dimensions in inches in the info window as well. Resampling the image results in a smaller image which is the usually desired effect when scaling and re sizing.

Usually you re size or scale down images in size since going "up" will always result in more distortion since the program has to make up the extra pixels, basically guessing at the probable result.

Changing the resolution will change the final image size but not the pixel dimensions. The number of pixel remains the same - just the number of pixels per inch will change. Increasing the resolution to 250 or 300 is useful for images to be printed while the standard 72 dpi resolution is desried for web pages or screen viewing. Note: at this time you can only change the resolution for images with jpeg, tiff, and png formats.

You can visually see the final dimensions, pixels, and resolution in the info window which makes alterImage so useful.

The Crop function works best without using Scale or Size since those are applied first and to then crop may not create the desired result.


The image info box and other preferences

The Info Window

  1. Remember settings will retain all the settings when you launch alterImage next time.

  2. Copy into folder... will create a new folder for your converted images at the destination

  3. Delete originals: After processing each image the original will be deleted from the source folder. Use Caution - this is irreversible!
  4. When you drop an image into the source field, the image specs and a thumbnail will show in the prefs window. Useful if you want to crop an image or know the dimensions you are working with. If you drop a folder of images it will show the first image in the folder.


Additional preferences

  1. Use centimeters: show centimeters instead of inches in Info window.
  2. Always set destination: by default, if there is no destination chosen, alterImage CS will set the destination to the same as the source file when you select the source file. This setting will tell alterImage CS to always set the destination to the same as source even when there is a destination already set. You can always reset the destination manually even with this setting.
