Irfanview from http://www.irfanview.com is free and excellent, as is xnview from http://www.xnview.com.

You can also do things such as (a) choose the level of jpeg compression to give a satisfactory file size for your users, and (b) add a little sharpening, allat the same time to improve web quality.

Good luck!,

You need a program that does batch processing.

Yo Alan T, or anyone else. I down loaded the infranview program yesterdayand when I went to downsize some pics, which were all jpeg files, the program converted them into BMP files, which are way to large for simple e-mails. They were reduced in sizeon the monitor.What I do wrong?. How do I reduce the size, but still keep them as jpeg files?

Yeah..., I`m a "newbie" to the digital image world after decades with 35mm.

You'll see a field for the file type. That's strange (that you got .bmp files). I thought it defaulted to JPEG.

Anyway, you can either convert one image at a time (under Image, Resize/Resample), or you can convert multiple photos using Batch Mode. To use Batch Mode, go to "File, Thumbnails" and select a folder. Then, use the "File, Start Batch Dialog with Selected Thumbnails" menu choice. You can add more photos to the ones you want to process then.

Make sure to select a different output directory so that you don't overwrite the originals (especially since you don't want to ruin them if you make a mistake). Also, make sure to select the "Options" button by your file format you're saving in (which i THOUGHT always defaulted to JPEG), so that you can select the desired JPEG Quality.

Then, select the "Advanced" button and you'll have lot of options (including resizing, converting to grayscale, etc.).

Here is a screen capture... Note the Output format field towards the bottom. If JPEG is selected, you can also control the JPEG Quality (I clicked on it so you can see the box that comes up), as well as whether or not you want to retain the EXIF, etc. Lower Quality = Smaller Filesize

If you're not using batch mode (converting one file at a time instead), when you use the save aschoice under the file menu, you can set the file type and options there.

I use PhotoFiltre http://www.photofiltre.com/ (free) which is like PS but without the levels function and a few nice plugins too.

Imagemagick is a command-line tool allowing to perform many different operations with images

http://www.imagemagick.org/script/index.php

since you can run it from command line you can write a script to do batch processing. For example I wrote a script to pad images to desired resolution and put a date label (besed on exif) on the added white space.

I am interseted in how you achieved this:

What I look for is a program that will determine the correct orientation of my photos by checking the vertical to horizontal pixel ratio, then add a black or white border such that the resultant image will be 1:1.5 or any other ratio of my choice, 10"x8" for example. The ability to add text into the border would be a bonus. I don't want to re-sample, just change the canvas size to get the correct ratio with max photo info.


Does the batch routine take account of the original ratio and orientation ? sometimes after selective cropping I have an image which is 1:1.1 ratio.

I'm batch resizing to show wide pics on my new plasma TV that comes with a card reader.

Be aware that some batch resizers (my version of PS and PS pro does this) strip or modify each files EXIF header making it unreadable. A bit like the problem of editing a pic and putting back in your camera to show on a TV when the camera throws it out as an 'invalid format'.

IRFANVIEW does batch resizing and does not strip or modify the data (unless you want to change it) and I thoroughly recommend it. It was the last prog I tried, when it should have been the first!
