    ..raw pictures were taken on a canon 10d and processed and saved as
    ..tif in photoshop.

    these files are too big and needed in .jpeg format.

    how do i batch convert a folder full of .tif files to .jpeg ones in
    irfan view.
    The goal is to provide some web images that will be relatively quick
    loading and if somebody wants to make a print out of them they would
    look ok up to 6x4inch print size. (That would be about 640x480,

    Thank you for the help!

    IT is very exciting now!

    Most still need wire unless you go blue tooth from what I seen.

    I use IrfanView for reviewing my pics, but I NO longer use it for resizing
    and instead use a more complete photo editing product Paint Shop Pro (or
    Photoshop Elements will work too). IrfanView comes with a help file, that
    has a shortcut in the IrfanView Start Menu folder. It is called "Command
    Line Options" and it has several excellent examples that will answer your

    I see you've got the typical variation of pointless and "RTFM"-type
    answers so far. Now for something actually useful.

    Assuming you have a fairly recent version of IrfanView, you just go to
    File -> Batch Conversion/Rename...

    Navigate to the folder with the desired pictures in "Look in:"; select
    the pictures you want and "Add" (or "Add all" if appropriate) them to
    the "Input files" list. Select your output directory and "Include
    subdirectories" if desired (I'll usually click "Use this directory as
    output" and then add "smaller" to the end of the folder path; this
    creates a new folder called "smaller" under the source of the pictures,
    and puts the resized ones in there).

    Under "Work as:", select "Batch conversion" or "Batch conversion -
    rename result files" depending on how you want them output (I go with
    the former, using the above directory settings).

    Set "Output format:" to "JPG - JPEG Format" and use the Options button
    to adjust JPEG settings as needed (I usually find an 85% compression
    setting works well for web images).

    Check the "Use advanced options" button and then click "Set advanced
    options". In the "Set for all images:" dialog, click the "RESIZE"
    secion, and select your desired resizing parameters (hint: if you "Set
    both sides to:" and enter 640 for both width and height, making sure
    "Preserve aspect ratio (proportional)" is checked, it will resize
    pictures so the maximum of either dimension is 640 - portait layouts
    will be 640 high by whatever smaller width; landscape will be 640 wide
    by whatever appropriate height).

    There are also options to alter color depth, flip/mirror/rotate, adjust
    bright/contrast/gamma/saturation/etc., add text to images, and more, as
    part of the batch process.

    Once you have those settings as you want them, click OK (you can also
    "Save settings" if you plan to use the same settings regularly). When
    you're ready, click the "Start" button at the top beside the "Input
    files:" list, and watch the fun!

  7. One particularly useful thing to do while downsizing images is a small
    amount of sharpening after the resizing. Irfanview can do that as part
    of the batch process. Check the "Sharpen" box in the batch dialogue,
    then enter a sharpening amount. I prefer something like 10 (out of
    1-99) which is relatively subtle.

    Cool idea, I'll try that. Thanks!
