- Batch Image Resizer!
You can crop and straighten any image manually, and the cropped part will be resized as required. Everything in a single operation! Most other batch image resizers would, at best, allow you to align the crop rectangle automatically, without any manual control. With Resize Sense, you never need to enter the same configuration twice! Just save your size configurations, as well as output settings file naming and format , as custom presets.
With the custom size presets defined, you can save every image in several sizes at once! Moreover, using custom saving presets, you can even save every size in its own file format and with its own filename pattern! Resize Sense supports the Small and Large Batch modes. The former is convenient when working with relatively few images and performing many customizations manual crop, rotation, etc. The latter is suitable when processing thousands of images.
Even the basic act of saving your work is highly configurable. You can save into a single output folder or at the original locations.
Replicate the original directory structure if needed. Use image information such as size and metadata in the generated filenames. And of course, you can choose the output image format, define JPEG quality, etc. Resize Sense has a companion application, our flexible batch image watermarking utility Watermark Sense.
The two applications are mutually integrated to act as a single application if needed, while keeping things so simple and straightforward as possible. Together they form a flexible and efficient image processing toolset for web publishing and similar needs, for those who need to obtain top quality results quickly and easily.
