Saving to PNG Painfully SLOW

[serendigity]

Anyone else experiencing very very slow times to save PNG with the latest Photoshop version?

I can save PNG using Apple Mac with the simple Preview app in a fraction of the time Adobe Lightroom takes. Is it just a bug in my version, or does everyone else experience this as well?

I do not know when saving a png started taking so long its been a problem for a long time. I have removed some versions of Photoshop. Currently I have CS2, CS3, CS6, CC 2014, CC 2018, CC 2019, PS 2020, and PS 2021 installed.  I just tested one 8MP Image with these versions.  CS2, CS3, CS6 and CC 2014 took around 6 seconds to save the imags as a png file.  CC 2018, CC 2019, PS2020 and PS 2021 took around 30 seconds to save the same png file.  I could not test CC2015, CC 2015.5 and CC 2017 for I have removed them from my machine. I think CC 2014 was the fastest was actually under 7 seconds  where  other three  were over 7 but under 8. But then how good are my 80 year old reflexes on a stopwatch.

So for a major app that I am spending over a hundred dollars a year to use this is utterly unacceptable. Who does their beta testing?   How do I get the eyes of the engineers on my issue?

Use Adobe feedback.photoshop.com  site report this bug. Adobe most likely knows about this and may not fix it for all we know. If unacceptable you can always cancel your plan pay the early termination fee and be done with Adobe.

Thanks. The feedback link you posted just loops back to this forum. Adobe doesn't want to hear about bugs or fix them, why would they? They get paid every month now regardless.

Try this to save png:

1. Open the File menu.
2. Click Export > Quick Export as a PNG.

[Multifun5]

Thanks, that helps!

[Multifun5]

Yes, that seems to be faster because it doesn't spend time creating a dilaogue box and preview. Good tip, thanks!

[LeoAmaralTr]

This really helps! Thanks! I can't believe that I've been using this super slow save option when there was this option to do it instantly all along. It's like the dumbest thing: "May I offer you a longer save accompanied by lag and stutter, Sir? Or would you rather an instant save?"

Apparently for the "Large File Size (Fastest saving)" option, that actually uses default PNG compression (zlip level 6) 🤔

Small and medium do use the higher level, but strangely the file sizes are exactly the same.  (The "FLEVEL" tag in the file apparently tells the compression level range, but not the exact number. Default is always 6, but "maximum" compression can be any from 7-9).

Kind of counter-intuitive. Really wish there was an option to use a lower compression level, since even level 1 compression is not THAT much larger than maximum compression level 9. Though of course this will heavily depend on the content. 

Here's the results of a test I did one time, this was a photograph image though. The difference is probably different for graphics.

Why doesn't Adobe make the Quick Export as a PNG the default behavior when
saving as a .png file?

Yes saving pngs in Photoshop is really bad.

I have a really good computer and sometimes saving pngs takes 5 minutes +

Using 85% CPU and 40-70% RAM....

For example if i want to save 6000x4000px 300dpi png.

But anyway,

this problem existes since years. And they will not be able to change that...

You have to deal with it. For other people who sometimes have to wait for 15min+ saving times, they work on 2 computers haha 🙂 Save on one, and use the other one to work on another file...

[JJMack]

I normally equate png image files with web usage for images where transparency is needed in which case the png will be displayed by a web  browsers.  Therefore a 6000px by 40000px 300ppi png image does not make sense to me. Also saving png with no compression seems to be the fastest way to save png files. However, it depend on which version of Photoshop you are using how long the save will take.  On my Windows 10 machine saving a 6000px x 4000px 300ppi png take CS6 less the 5 seconds to save the png where photoshop 22.4.4 takes around 20 second to save the same png. CC 2014 the saver takes forever. CC 2018 also takes 19 seconds.  So I avoid using PNG files I only PNG file when I need a Flat image files the has transparently in the image. I do not create image for web usage. So it does not bother me how long it takes Photoshop to save png files.  I believe Adobe knows Photoshop has an issue saving png file it hard to miss how long it takes Photoshop to save a png file.

[Multifun5]

Some animation programs, like After Effects, Flash and Spine use PNG files, and sometimes those files need to be big. There are more uses for PNG with transparecy besides just display on a webpage. It's crazy that my very expensive and very modern mac, with tons of ram and speed, runs as slow as a 90's computer at times when I'm using photoshop.

[Earth Oliver]

how are you saving the png? save as? save for web? export as? quick export?

[Multifun5]

"Export as". Should I be using a different method?

Thanks.

Silly slow.
Bad coding. 

[joeri.kassenaar]

Just save it as anything that supports transparancy and use a real tool to convert.
Maybe even have a folder automation.

It's just silly how bad such an expensive piece of software is so bad at something so basic as saving.

Even on a Mac Pro it’s slow to save PNGs ... Aslowbe Photoshop
