Method 8Īnother option (for Windows users) is PNGSlim. I would love to see this idea extended further, or see JPEG 2000 (which I believe supports alpha channels) garner some browser support. Still, for photographs with an alpha layer, it does the trick and saves some bytes. It starts to lose quality from the original image about the same way a JPEG does, but unfortunately at a much faster rate. Image Analyzer has the ability save lossy PNGs while preserving the alpha layer.
It performs additional compression of the resulting PNG file, something that other quantisers such as pngnq don’t do.

It also preserves full alpha transparency. It quantises the image so it only needs 256 colours, and then stores the file as 8-bit indexed PNG.

There’s a free online service at that performs pretty advanced lossy compression.
#SUPER PNG COMPRESSOR MAC#
That’s a Mac application, but tools for individual techniques are available for other platforms.īy the maker of ImageOptim is ImageAlpha which is a lossy png optimizer, It will convert your 32bit png into 16bit color or less.
I’ve found 3 different methods for lossy PNG (lossy averaging filter, vector quantization, median cut posterization) and implemented them in ImageAlpha. Alas, Pixelmator is still woefully lacking in PNG export options so, for now, this is what I’ll use. It’s not perfect in that it’s still mostly automatic, so I can’t fine tune more lossy options. The idea is that it picks the best tool for the particular PNG. It comes with OptiPNG, PNGCrush, AdvPNG, PNGout and a few other’s you can add-on. What it is is a wrapper around several different PNG optimization tools. You can choose to dither or not, of course - sometimes the file size of the quantised PNG is larger than the original RGBA, so you may have to play around with dithering settings to get something that works. It’s command-line only, but if you don’t mind that, it’ll be a handy tool in your arsenal. It gives pretty good dithering, and one really really nice feature is that it lets you preserve the 8-bit alpha channel rather than quantising it to 1-bit (remember the bad ol’ days of GIF?). Even for mobile broadband devices, bandwidth won’t be a concern for 95% of users within the next two to three years.

But bandwidth is fast becoming a non-issue, and in parallel with that the importance of image super-compression, minified code and all the other optimization tricks that have exercised the webdev community for years is fading rapidly. That said, I’m fairly certain png output in Photoshop hasn’t changed since roughly the end of the last Ice Age, and I don’t see any signs of it changing any time soon, so if you have any version of PS its png capabilities won’t be outdated.Īnd all that said, this is all about bandwidth. It’s been a while since I played with it, but iirc it did include lossy (color table) compression. Irfanview has excellent png support in its PNGOUT plug-in, and it’s free for non-commercial use.
One or more of those might well fit the bill. There were some good answers to this png compression question on SU. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you. I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem.

I could even fire up Ubuntu if I had to, I suppose… How to solve : Is anyone familiar with a tool (other than PhotoShop) that would offer up some lossy PNG compression options as well like reducing the color pallet, converting 32bit to 24 or 8bit, etc?Īddendum: I’m open to OSX or Windows software. I can dump it out as a PNG then use one of the many great PNG optimizers like PNGCrusher and can reduce the size fairly well.Īlas, all of the PNG optimizing tools I’ve found are purely lossless. On OSX I’ve been enjoying Pixelmator but it has woefully inadequate PNG export support. I do primarily web work these days and don’t do enough side gigs to justify keeping up with the Creative Suite beast.Īlas, that does bring to the table some limitations. I’m trying more and more to get by sans PhotoShop for my personal/freelance work. All we need is an easy explanation of the problem, so here it is.
