The fact of the matter is, the faster your website the better. This one is huge for me, and will be for anyone else who relies on their website to earn a living. If you have folders containing large amounts of JPG images on your desktop (waiting to upload to client galleries etc), reducing the file sizes here will result in faster boot times and computer operation, particularly on older devices.īottom Line: JPEGmini has sped up my laptop by increasing my available hard disk space. This is especially apparent on devices with limited solid state hard drive space, such as laptops. No matter what computer set up you’re running, if your hard drive has more space, it will run faster and more efficiently. I can now provide the exact same quality of photo, at over half the file size. Wedding photographers, you’re going to love this! Ever tried to squeeze 11gb worth of client JPGs onto your 8gb USB thumb drive? Of course you have! With every new camera release, it seems like with all the new mega pixels, our file sizes are doubling and doubling.Īnyway, from now on, when I deliver HIGH RES photos to my clients, I use the JPEGmini Lightroom plugin (more on this later) to export my photos at half the size of what they would have been having used my previous export method, and easily fit every file onto my USB thumb drive.īottom Line: JPEGmini has meant I don’t need to order any costly new USB thumb drives. ONE THIRD! With no noticeable loss in quality. You might say, what’s the point in this? Storage is so cheap these days! Why would I need to save space? Well, I’m glad you asked…īottom Line: JPEGmini has reduced my Lightroom JPEG backup catalogue by 1/3.

Since waking up this morning, I’ve reduced the size of my entire photo backup library on my main iMac (and 4tb Mybook WD external hard drive), my partner’s Macbook Air and my old and decrepit Macbook… saving over 26gb in hard drive space!

If you don’t have time to read the rest of the review, this is all you need to know: JPEGmini is an essential piece of software for anyone who stores images on their computer.

With apps and software available for everything under the sun, it’s rare that something new comes along that you find absolutely essential.įor me, that piece of software is JPEGmini, an amazing mac/pc application (and Lightroom plugin) that uses patented image optimisation technology to reduce the file size of photos significantly (up to 80%), while preserving their full resolution and quality. Chroma sub-sampling occurs at up to 50% 'quality.' However, unlike normal Photoshop saving, there is a big file-size jump when you move from 50% to 51% because extra compression isn't being performed to maintain a linear file size relationship.It’s not often that that you try a piece of software that completely blows you away. Photoshop's 'Save for Web' dialogue doesn't behave in quite the same way. As such, it's worth avoiding saving JPEGs at 54-61% in Lightroom. As a result it makes more sense to think of the slider as controling file-size, not quality, and to avoid saving at JPEG quality level 7.Īlthough it's labelled differently, Lightroom appears to use the same 0-12 quality scale as Photoshop, just re-mapped as percentages. However, because the full chroma data is so much larger than the sub-sampled version, the chroma and luminance information are then more compressed to stop there being a huge leap in file size as you step from level 6 to 7. Up to quality level 6, the software conducts chroma subsampling, while at 7 and above, it does not. It's a piece of information that resurfaces from time-to-time, but one we've never covered before so we thought we should explain: He discovered that Photoshop's JPEG 'quality' slider isn't as linear as you might think. In response to an interview with ICVT on .il, PetaPixel's Michael Zhang looked into Photoshop's JPEG specs.

( via PetaPixel)Ĭlick here to find out more about JPEGMini Photoshop quality/size confusion: Meanwhile, the news has prompted blog PetaPixel to reiterate the little-known quirk of Photoshop's JPEG quality slider that means your images may be better saved at quality 6 than 7. At present the system can only be used via the company's online service. The company says you can expect a 50-80% reduction in filesize over a JPEG that hasn't been intelligently optimized. The company's JPEGMini system analyses each image to assess the maximum compression that can be applied to an image without loss of perceptible quality. Israeli technology company ICVT has developed an method to optimize JPEG compression.
