Any recommendation for an equivalent tool to pngcrush for JPG images? Or for other formats?

"With the increased spatial resolution and number of spectral channels, each LandIS instrument is expected to generate up to 1.8 Gbps of raw science data, excluding embedded telemetry and metadata. Given the mission’s primary goal of capturing imagery of all land surfaces and inland water bodies, which collectively cover approximately 30% of the Earth’s surface, each LandIS instrument could produce nearly 6 TB of image data per day. The management of this large volume of data, particularly the storage and transmission to ground stations, presents a significant challenge for the mission architecture. Historically, the Landsat Ground Network has supported X-band frequencies with roughly a 384 Mbps downlink rate to transmit science data (Masek et al., 2020, Irons and Dwyer, 2010). However, with approximately 105 min of contact time per day, the available data transmission volume would be insufficient to fully downlink the expected daily generated data volume, leaving a significant portion of the science image data undelivered. To address this issue, a shift to higher downlink rates using Ka-band frequencies is necessary. With potential Ka-band downlink rates of 2.6 Gbps, and the same 105 min of contact time per day, the transmission of more than 2 TB of data per day would be possible. Although this represents a notable improvement over X-band, this Ka-band system still cannot accommodate the full volume of data generated by the LandIS instruments."

I've always been a big fan of squoosh, the web app that allows you to compress an image in several formats without losing much quality, but it does not work properly on mobile — on iOS, at least.
That's a problem when I want to share pictures taken from the phone camera, since they are large.

So, unhappy with apps on the App Store, I discovered a-Shell, an app that allows you to run shell commands on your iPhone… including magick!

So I spent too much time created a Shortcut that allows to:

• choose an image from Apple Photos app
• resize it and compress it (-resize 1500x1500 -strip -interlace JPEG -sampling-factor 4:2:0 -define jpeg:dct-method=float -quality 75)
• copy it to the clipboard
• (removes the temporary files, of course)

So the compressed image can be just pasted anywhere, e.g. on Phanpy.

Here is the Shortcut link for anyone interested: https://www.icloud.com/shortcuts/486776b73d554396a7ace51e18984a0e

A short primer on the AVIF image format, what benefits it offers and how to make use of it in your work. I personally think it offers a LOT and is probably going to be replacing PNG in the near future. WebP is great, but doesn't serve all needs, AVIF has some drawbacks of its own, but is probably the stepping stone we need to adopt before moving to the next thing.

I’m looking at some random recent small imprint or self-published books from my library which contain artwork and digital image scans with digital artifacts or blurring. These days I presume some of this is simply caused by most people using something like JPEG format when sourcing digital imagery, not realizing it is a lossy format. #imagecompression

Are there ways that we can lighten the load on the #mastodon servers?

I've recently been nerding out about the image #compression choices/tools that "LOW<-TECH MAGAZINE" uses (low resolution, single channel, dithered pngs) and I'm wondering whether we should be thinking about that kind of stuff as we move away from the buffet of high-gloss video-centering social media sites...

How can we save money/energy @fosstodon?
