There are several folders with pictures (~10000 images).
Task: reduce them by 1 pixel on each side. What software can do this?

The above, SnagIt and even Photoshop. There are many options, there is little input data for a full-fledged advice.

If there is MS office, then the same Microsoft Office Picture Manager.

Under Windows, XnView will be an excellent choice

In Photoshop, write down the action, then run it for the folder, but I'm afraid for ~ 10,000 images you will need to leave the computer running for a week ...

Something like this:

$srcPath = ".\Pictures"
$shrinkBy = New-Object Drawing.Size 1, 1
foreach ($file in dir -r -inc *.jpg, *.jpeg, *.png, *.gif $srcPath) {
    echo $file.FullName
    $src = [Drawing.Image]::FromFile($file)
    $dest = New-Object Drawing.Bitmap $src, ($src.Size - $shrinkBy)
    $format = $src.RawFormat
    $src.Dispose()
    $dest.Save($file.FullName, $format)
}

Saves changes directly to the original file (too lazy to mess around with recreating the directory structure), so it's better to work with a copy.
Repacking with default encoder parameters. If you need others, you can tinker with the Save overload.
To change the interpolation parameters, you will have to create Drawing.Graphics and draw there.
