best software for resize a picture ?

.. When you have a big, final picture on LR, Photoshop, Capture one etc ... and you want to reduce it for mailing, forums, galery... something small, like 1024*768 or 1280*800... have you find a good tool ?
i'm not impressed by algorythm and results from Adobe's resize process...loss of sharpness etc...not very convincing
... i found "photofiltre" (studio X) with Lanczos sampling, sometimes good... sometimes not...
And you ?

Recently while producing a few "web" resolution jpgs (1900x800, 961x290) I've used Pixlr.com's online app. It's easy to resize and then crop to my specific sizes for this project. I can't say how this method compares to others as I've not done a side by side but the client was happy.

The other app that I use is FastStone, which is also my default jpg viewer. FastStone's resize/resample offers 11 different filters, including Lanczoz3 (default setting). Again, I've not done a side by side comparison of the output but FastStone is free and worth trying. I know several other forum members us it.

I also like FastStone Photo Resizer - Powerful Image Converter/Resizer for this purpose.

Me, too. I use it for chimping as well because it loads the images quickly.

Have you played with the Export options in Lightroom? There are a couple settings for sharpening in addition to the standard JPEG "quality" slider.

I'm not as familiar with Photoshop. It seems its "Export" options are not identical but do also offer control over how the downsampling is done.

After using Photoshop and Lightroom for many years and also trying other applications (usually upsampling but quite a few downsampled for web I have always found them to be more than up to the job, many times at least as good and sometimes better than specialist apps.

Therefore I was more than a little surprised to see complaints of downsizing algorithms being sub par and loss of sharpness as this should not be the case. However I have seen poor results from either incorrect settings in Adobe products and more so with the output results from certain image hosting sites due to them applying resizing algorithms to the output data.

Not saying that poor results cannot be had but I would like to see some objective side by side testing, ideally with access to the same raw data and certainly with some detailed step by step description and software version, as I may be missing something

That is a very good thread.
I just downloaded/installed that software and I can't seem to find out how to specify an "output folder" ...
Can anyone help me with this here so I can try this software?
Thanks!

Like Tony, I have the same experience with PS and LR. They have been the best for me, but requires more user skill because they are not simple programs. On Macs, for users that are new to PS or LR, one may be better off just using the Preview app for resizing.

Also if you regularly share to FB or Instagram or a particular site, it is worth experimenting to find what works best for that site. In some cases, it is better not to downsize yourself, but let their posting software do the work. In other sites, you may find the opposite. More times then not, I find it is my own fault when there is something below par on the results.

Not unlike camera lenses and sensors, we often expect a better monitor, like a retina display or 5K to look better, but sometimes it will make an image look worse because it is showing the lack of resolution in the downsized image that was acceptable with an inferior resolution display.

Select the images. Go to Tools menu. Select batch convert images. You should see the selected image names in the right-side panel. Below that is "Output folder". Either browse to the desired folder, or uncheck the little box in which case the smaller images will overwrite the larger files in the current folder.

Below that is "Advanced Options", which you click to get to the output size.

While I have Lightroom and Photoshop - iPhoto (now that it's back in OS X El Capitan) is about as easy as it gets.

As long as you have FastStone Viewer it's not neccessary to install FastStone Photo Resizer or..?
For years I've been using FS Viewer to view and simple batch process my jpeg's for web + +.

Just select one or several picture and press F3 and you will get up the same tools as Photo Resizer:



By "Settings" plus "Advanced Options" you'll find all the ordinary Parameters ++ to change.
As TomTom mention; selecting the optimal filter (algorithm) for resampling are essential.
As long as we're discussing optimal settings for web; try at least "Bicubic Sharper" as an
alternative to default "Lanczoz3".

Finally you can save all your spesific settings optimal for web transformations etc etc.
This is the same for both programs. Or have I missed something?
