JPEGmini – A Free Web Based Tool To Compress JPEG Files Without Losing Quality
JPEGMINI is a free online tool to easily compress high quality JPEG file size to small file size without losing its quality. The site also offer user login for bulk uploads and unlimited usage, but its not mandatory if you want to compress single JPEG images.
Technology behind JPEGmini
JPEGmini is a patent-pending photo recompression technology, which significantly reduces the size of photographs without affecting their perceptual quality. The technology works in the domain of baseline JPEG, resulting in files that are fully compatible with any browser, photo software or device that support the standard JPEG format.
JPEGmini is capable of reducing the file size of standard JPEG photos by up to 80% (5X), while the resulting photos are visually identical to the original photos. The JPEGmini algorithm imitates the perceptual qualities of the human visual system, ensuring that each photo is compressed to the maximum extent possible by removing redundancies, without creating any visual artifacts in the process. This enables fully automatic, maximal compression of photos with no human intervention required.
Performance Chart
| JPEG Photo Resolution | Typical JPEGmini file size reduction |
| 8 MP and higher | 70% – 80% |
| 5 – 7 MP | 60 – 75% |
| 3 MP | 50 – 60% |
| 2 MP | 30 – 50% |
| 1024×768 | 25 – 35% |
| 800×600 | 20 – 25% |
| 640×480 | 10 – 20% |
So the next time when you upload high quality JPEG’s use JPEGmini to save bandwidth and web page loading time.JPEGmini
