Thumbnail picture generator.

Overview

ThumbsUp lets you create thumbnails for your website in seconds. Drag them to its icon and it converts them in a batch with the previously set options. Of course, ThumbsUp works with all image formats supported by OS X including PDF documents and QuickTime movies. Set desired size, quality, sharpening, and anti-aliasing; scale images by percentage or maximum size.

This is the best resizer I've found, ThumbsUp can not only create thumbnails or icons for images and movies. ThumbsUp goes far beyond, it's a superfast batch image resizer, a format converter (for example jpg to tiff, etc.) and ThumbsUp can sharpen (!) and antialias (!) the images (not only the thumbs as falsly stated in the manual) and can do all that in one fast step. ...and this FREEware, wonderfull, thank you very much.

ThumbsUp quality when downsizing jpegs for web without sharpening is just a bit worse than Preview or ResizeMe and significantly worse than PhotoBatcher at the same sizes. Visual comparison here: foliovision.com/2016/01/best-image-resizer Sharpening just makes matters worse. ThumbsUp does match Adobe Photoshop CS6 and JPEGmini both of which are significantly more expensive. On the other hand, the options are simple and the price is right. ThumbsUp is coded by DevonTechnologies so one can be sure the core is rock solid. A big thanks for excellent freeware.

This is a handy program however it has it's flaws. When I reduce a JPEG in dimensions it frequently doubles in files size. I can easily fix this using ImageOptim, however it does seem strange that this happens.

This would be a great application except it doesn't handle nested directories (folders/subfolders). Or rather it handles them in an idiotic way. When you drop a directory tree on ThumbsUp instead of asking you if you want to overwrite it or if you want a resized copy somewhere else in your computer it creates a subfolder inside every one of the original subfolders and calls them all "resized". If you want a resized copy of the original directory tree you have to move and rename each one of the "resized" folders. If all your images are in ONE folder without subfolders it works fine. You only have to rename that one folder.

Excellent, does everything in the right way. I couldn't ask for a better thumbnail/image resizing tool than this.

I have used this for a long time now, and I hate to have to complain about such a great little free app, but it can't seem to do the first page of a PDF file if the file has more than one page. It always does the second page. Very annoying, but otherwise very use-able.

I should also add that ThumbsUp can't make a thumbnail with the EXACT same name of the original (with a different extension) and put it in the same place as the original. It either must change the name of the thumbnail, or put it in a separate folder, even if the file type changes. This adds unnecessary extra steps.

Huh? Tried without success, Terminal/Shell needed? - Are you shure your comment is related to ThumbsUp? - With the utmost probability you've gotta be kidding, but unless: You _don't_ need the Terminal/Shell... ThumbsUp is a standalone app, nothing else needed, maybe you are a bit alienated by its small file size of 704k, but it is a real app. - The programmers of ThumbsUp are high professionals showing huge knowledge not huge apps... they know how to code small, efficient and fast apps, it doesn't need some megabytes of code for such an easy exercise as resizing & sharpening images. Again: ThumbsUp is a _droplet app_, you start it by doubleclicking on it, configure your desired settings and then drop imagefiles on it. It will do its job and after a short while your images are smaller/bigger related to your settings. Just read the "ReadMe.rtf". The one thing that you can't read in the "ReadMe.rtf", is just that ThumbsUp can not only sharpen the previews but the images itself. Alright now?

I tried it, but without success. I'm not very familiar with the Terminal/Shell.

Is this App scriptable or can be fired from the unix shell? I would like to use it for folder actions or droplets.

Hi TEKL, ThumbsUp in fact IS a: -droplet- You may ask the developer about scriptable/shell. Or just try it yourself - the download is only 307 K...
