The JPEGmini Photo Optimization Software is a photo resizing application designed to reduce overall file sizes without sacrificing image quality, resolution, or format. Capable of lessening your JPEG file sizes by up to 5x, this tool provides an efficient solution for freeing up hard drive space and shortening upload times.
This program is a desktop application used to reduce JPEG image file sizes in order to save hard drive space and lessen the amount of time to upload or share JPEG files.
JPEGmini is capable of reducing the file size of a standard JPEG file, up to 28 megapixels, by up to 80% without affecting the file's native perceptual quality. Resolution, overall image quality, and compatibility all remain the same as the original file. This compression technique utilizes an algorithm that imitates the human visual system to ensure the overall appearance of the image remains the same while removing redundancies within the file structure without creating any perceivable aliasing or artifacting.
The JPEGmini technology utilizes a two-step process to first analyze the file's image quality and assess how much compression is possible without a perceivable reduction in quality. Secondly, the system then utilizes a unique JPEG encoder that is tailor-made to the file itself to apply standard compression techniques that still allow for consistent resolution and image quality when compared to the native file. This compression technique has been tested in accordance with the ITU BT.500 standard to deliver an unnoticeable visual difference between the original file and the JPEGmini-compressed file when viewed at 100% on a monitor or printed at 200dpi on photo paper.
JPEG resolution (typical file size reduction)
8MP or higher (70-80%)
3-7MP (50-70%)
1-2MP (40-60%)
Less than 1MP (30-50%)
