Quick Resizer is the fastest and simplest app for resizing your images.

Resize one or more images by dragging them on the app or opening them from within the app. PNG and JPEG files are supported, and the resized images will be optimized for use on the web.

Simply drag your image file (or files—batch resizing is simple!) on the app, set the size and constraint for the resizing, and hit enter!

You can also set the app to quit automatically after processing images, change the JPEG compression quality, and decide whether to sharpen images when they are reduced in size.

Please send any questions to our support email address, and let us know what we can do to make this app better.

Great drag and drop resizer

I just wanted a quick resizer where I could easily resize square images. It works well in that I can specify a new size to use for all images and then just drag the images onto the icon or application panel and press “go”. My one and only complaint is that there is no option to overwrite the original file. It defaults the original filename with “-resized” appended to the end which you then have to erase (making the Quick Resizer more of a Less Slow Resizer). I seriously doubt that many people will use that default so it would be better to just put in the original filename with no extra text and allow the user to either accept it (overwrite original) or change it. If you HAVE to have an extension, please make it only 1 character long!

can only resize one way despite it saying horizontal and vertical. The input stays the same when you click accross and contrains the image, useless.

doesn't do batch changes

Its Ok. Doesn't do batch changes and it wouldn't do drag and drop (I had to use file and open each time).

It was fast and simple which is good. and cheap.
