on wikipedia you will find more info aboit the compression method used.

I still fail to get decent size jpg:s from NIK Sharpener compared to the same image exported from PL7. I exported the image with the same settings in PL7 and NIK Sharpener. The image sizes were the same but the file sizes differed from 1.98 MB in PL7 to only 414 KB in NIK Output sharpener.
PL v.7.3.0
NIK 6 most recent
Please check your two screenshots, set the Resolution to the same value and try again.
Has been done - same result.
See results of jpgQ Estimator showing that NIK exports at 86 - 90 % and PL7 with 100 % both set at 100 % at the output settings. This did not happen earlier with old NIK and this is the issue I am trying to get solved.
Exporting with PL7 using 86 % compression gave a file size of 496 KB. That is about equal with the size obtained with NIK at 100 % compression and no sharpening applied. There must be something odd within the settings of NIK (in my workflow or computer).
There’s also a difference in saturisation.

Hi Klaus,
when I tried yesterday, what I wrote to you, the size of Nik 6’s output JPEG file
was even slightly larger than that of PL7.
As I had deleted those files I checked again.
-
The files with the “-1” addendum were
takenexported with the following settings
and Resizing mode set to Fit
export to disk
.
export to Nik
.
and in the Nik Collection Preferences → JPEG quality: 100%
.
Unfortunately the Nik Collection layout is so dark,
that one easily misses those options. -
The files w/o addendum were
takenexported with the very same settings,
but Resizing mode set to Longest side
Yes, slight. That I discussed earlier here but the issue became less and now I feel the file size is the main issue to be solved.
Sorry for asking a possibly stupid question: What is the issue of different file sizes?
Different apps produce different output, because they are programmed in slightly different ways, use slightly different precision and rounding etc. So what?
Or is it that you need to be within a certain file size for publishing images on a site that sets such limits? Or is it for curiosity/interest?
It is the need to be within a certain file size - in my case 2 MB max and 1920 x 1080 pixels max.
Hi Wolfgang,
Now as I saw your screenshot about NIK collection preferences I made the following:
- Uninstalled NIK Collection 5 and 6.
- Re-installed NIK Collection 6.
- Opened NIK Sharpener as stand alone from Windows Program files folder (never done before)
- Found NIK Collection Preferences dialog box (for my first time) and changed the jpg quality settings from 80 % (default DxO ???) to 100 %
Then, my image came out at about 2 MB as should after being saved from NIK. I continue testing but believe I have good chances to be happy with this.
Odd that I found no indication of NIK Collection Preferences dialog in the manual or in the software installation/usage dialogs. It was you picture that made me search for this. I have since long been convinced that there must be another - serial connected - setting for jpg compression. Its there.
I hope DxO would clarify the manuals regarding this.
Thank you Wolfgang!
What you were looking for is shown

for Nik 6
in the online help → Shared interface and tools – Nik Collection Guidelines -
for Nik 5
in the user manual (pdf, page 130)
The problem is that in both cases the settings are displayed all at once, but not in the software. Instead the completely dark “modern style” interface effectively prevents you from noticing the bottom part – a bad GUI.
(not that I didn’t report it to DxO/Nik…)
Okay, that is the real topic at hand.
You want the file as big as possible (for less jpeg artefacts) but stay within limits.
