Instead of cropping from the sides to reduce the width as earlier FastStone added black borders to the top and bottom to increase the height. In this example, I did the same 400 x 300 to 300 x 300 resize, this time with smart-fill enabled instead of smart-crop. Smart-fill automatically adds bars on the edge of the image to manage aspect ratio mismatches without having to squish the image.

If there is a mismatch in both of the dimensions and in the aspect ratio then both cropping and resizing is done. resized to 300 x 300 with smart-crop enabled The result of such a smart- crop on our original image is shown below. Conversely, if either height or width of the new image matches the corresponding height or width of the original image no resizing is done and the image is simply cropped to fix any aspect ratio mismatch. For example, if you resize the original 400 x 300 image to 200 x 150 resolution with smart-crop enabled, the image gets simply resized and no cropping is done. If there is no aspect ratio mismatch FastStone will just resizes the image. If you reenable Preserve Aspect Ratio option and choose smart-crop, Faststone will automatically crop the image if the new aspect ratio does not match the aspect ratio of the original image. Original 400 x 300 resolution image Resized to 300 x 300 with preserve aspect ratio off Smart-Crop If you disable the Preserve Aspect Ratio option you will get a squished looking image as shown below. If the aspect ratio is different then things are more difficult. If the new image resolution you want has the same aspect ratio as the old image then you don’t need to bother with most of these options. Both sections have many common options, let us take a look at some of them. The In Print Size section is quite similar to In Pixels section except that here you specify the image size in inches or centimeters. In the In Pixels section, you can specify the height and width of the new image in pixels. Make sure that the tick box before resize is ticked, that would make the resize options visible.

This would make the Advanced options button visible, click on it to open the advanced options window. Next, make sure that the tick box next to Use Advanced option is ticked. Here you can add files to your selection or remove files from your selection. Even if you are a not going to do any batch processing, the Batch Resize option of FastStone is well worth a look since it has a lot more resizing options than it’s dedicated single image resize.įirst, select the images you want to resize, then choose batch convert selected images option from the tools menu. Batch convert gives you a lot of options like resize, crop, compress, rotate, color adjustments, add watermark etc. One of it’s most powerful features is the batch convert feature. For what is essentially an image viewing application Faststone image viewer has a surprising number of useful editing features.
