qimgv VS oxipng

about this time, i am a little more than intrigued and a bit confused. i use my image viewing program qimgv (github) by typing qimvg 87956_60.png and was shown a photograph of a man seemingly turning his head to look at me.

qimgv - Image viewer. Fast, easy to use. Optional video support. Very powerful, qt app, best for me.

I use qimgv, It's mostly frameless (It only has a window bar), supports going left and right through images, even sorted by date and even on a directory with 80k+ files in it. It also has some very useful features in the right-click menu and also has a folder view and is highly customizable.

I don't know exactly what you mean by "nothing", but JPEG XL is already supported for almost all image viewers on Linux installing the libjxl plugin system wide, and on Windows good image viewers like XnView, IrfanView e my personal favorite qimgv, and all most used browsers already supports jpeg xl, however is not enable by default and you need to enable it in the hide settings, but I agree that you probably will not want to use jxl if you are sharing images to other people all the time on different platforms and can't bother to decode before doing, or are using it on other devices that don't use a desktop OS, that is way I only recommend it to people that like "bleeding edge" stuff, my first recommendation is still use something like pingo if the original format is a must.

My personal favorite is qimgv. It even supports videos with an additional download, which is awesome for me.

qimgv can also save AVIF

7zip, Rufus, BleachBit, Bulk Crap Uninstaller, SpeedCrunch, ShareX, Keypirinha, Everything, OBS, qimgv and of course Nextcloud are all the essential free/open source software I need.

I have had good experiences with https://github.com/shssoichiro/oxipng . Although, I suspect this wouldn't give you nearly enough space savings as jpg.

If you do want the file as a PNG (for transparency and a common format that's well supported), but don't want it so huge, consider something like oxipng. https://github.com/shssoichiro/oxipng

oxipng, pngquant and svgcleaner — optimizing images

I wonder how `pngcrush` compares to `oxipng` (https://github.com/shssoichiro/oxipng).

Personally, I use `oxipng` if I want lossless compression. However, most of the time, I use `pngquant` instead, since it gives significant size reduction even at `99%` (I can't even distinguish between the original and reduced image).

    pngquant --quality=99 --ext=.png --force file.png

Depending on your workflow it might make sense to export PNGs directly from Affinity and then reduce their size with a utility like Oxipng, which uses all your cores to find the best algorithm for each particular image.

Assuming your frames are PNG files, you could use a lossless optimizer like optipng to try if their size can be reduced. I prefer oxipng, which is faster and multithreaded, and seems to have more active development.

Not sure what extensions of images you use, but if they’re PNG you could use oxipng: https://github.com/shssoichiro/oxipng
