compression is not suitable for charts, graphs, and text. But that
doesn't stop the digital idiots.

However, FOSS has an answer:

From the link:

"jpeg2png gives best results for pictures that should never be saved
as JPEG. Examples are charts, logo's, and cartoon-style digital drawings."

Installation

A compiled Windows version is available on the "Releases" page.

(It's jpeg2png.exe).

Under Windows, you can also drag-and-drop JPEG files onto the program.

Also, the example graphics really don't show any benefit. The first example, "Lena", the encoding is better than the bogus GIMP conversion, but the jpeg2png is worse than the original. Why not use an original JPEG as the base. And show numbers (file sizes).

Just my quick assessment.

There's no way you don't know about ImageMagick.

ImageMagick-im6.q16(General Commands ManuImageMagick-im6.q16(1)

NAME
ImageMagick - is a free software suite for the creation,
modification and display of bitmap images.

SYNOPSIS
convert-im6.q16 input-file [options] output-file

OVERVIEW
Use ImageMagick® to create, edit, compose, or convert
bitmap images. It can read and write images in a variety
of formats (over 200) including PNG, JPEG, GIF, HEIC,
TIFF, DPX, EXR, WebP, Postscript, PDF, and SVG. Use
ImageMagick to resize, flip, mirror, rotate, distort,
shear and transform images, adjust image colors, apply
various special effects, or draw text, lines, polygons,
ellipses and B\['e]zier curves.

The functionality of ImageMagick is typically utilized
from the command-line or you can use the features from
programs written in your favorite language. Choose from
these interfaces: G2F (Ada), MagickCore (C), MagickWand
(C), ChMagick (Ch), ImageMagickObject (COM+), Magick++
(C++), JMagick (Java), JuliaIO (Julia), L-Magick (Lisp),
Lua (LuaJIT), NMagick (Neko/haXe), Magick.NET (.NET),
PascalMagick (Pascal), PerlMagick (Perl), MagickWand for
PHP (PHP), IMagick (PHP), PythonMagick (Python), magick
(R), RMagick (Ruby), or TclMagick (Tcl/TK). With a lan‐
guage interface, use ImageMagick to modify or create im‐
ages dynamically and automagically.

The only digital idiot here is you. Going from a lossy format (jpg) to a
higher quality format (png) does NOT make it look any better. All you
will end up with is a larger file that looks exactly like the original.

You need to encode the original in png, not jpg. Once its in jpg, the
stuff that is lost is gone forever.

You can pour 2 gallons of water into a 5 gallon bucket. But it is still
2 gallons of water. You can take a crappy mpg file (at 64k for example)
and convert it to a CD. But it is NOT CD-quality sound.

And BTW, there are dozens of these useless utilities for Windows.
Because there are LOTS of people just as stupid as you.

I use imagemagick all the time. Sign the various spots in a document, then scan each page to JPEG format (better than PNG for emailing), save each one with an ordinal name, then:

$ convert *.jpeg official-document.pdf

Easy peasy!

We also used imagemagick (and libreoffice) to convert a variety of documents to PDF for a project at work (years ago). This was on Windows.

It's also an easy way to take a screen shot (root window or a specific window):

$ import screenshot.png

More options than you can shake a stick at.

It is useless to argue with total idiots but I have some time to waste.

This program is NOT a converter. Understand assholes?

This program addresses the following problem:

Certain types of digital images such as line drawings, text, cartoons,
graphs, etc. should not ever be compressed using JPEG compression.
The reason is that such images contain a lot of very sharp edges
that require extremely high spatial frequncies to reproduce. The
nature of JPEG compression is to throw away those high frequncies.

Needless to say, when such images are compressed with JPEG the
result is chock full of highly visible artifacts and distortions.

This jpeg2png program attempts to remove those artifacts and create
a distortion-free result that is saved as a PNG image.

There are idiots all over the Internet. Most, if not all, will
use Microslop Winblows to do their production work. When the time
comes to save their images they just stupudly press the JPEG compress
button without enderstading the consequences.

I encounter this idiotic junk all the time and now there is a specific
program, jpeg2png, that is designed to provide a remedy.

But one cannot fix stupid, just like one cannot argue with idiots.

So I look at the next solution, which says to keep the related packages at their current version.

It turned out that the update broke Qt. Skanlite, qsynth, skanlite.... none would work. I had to go back into aptitude, update again, and select a different solution.

Hardware note: I saw a cheap ($7) USB-to-3.5mm headphone jack and bought it so that I could free up my Berhinger UCA202 audio codec box. Plugged into a USB-2 port on the back of the mini PC, plugged in my speakers, tweaked mpd.conf and used pavucontrol to make that dongle the default audio output.

Also edited .xbindkeys (changed "CODEC" to "Audio" to reflect the new device's name as shown via "aplay -l") to control the new device using the amixer app.

Nice change o' pace.

As the references in the web page attest, the information is not really
lost but can be inferred from the stored quantization tables:

"Our algorithm is based on an adapted total variation minimization approach constrained by the knowledge of the input intervals the unquantized cosine coefficients belong to. In this way, we reconstruct an image having the same quantized coefficients than the original one, but which is minimal in term
of the total variation."
