Free image compression software/website?

[paulpmp4]

I have created some images for my school website but some of the images take a while to load. Does anyone know of any free wesbites or software that will compress the image to make it smaller without losing image quality? Thanks in advance.

Most installations of Office (all?) come with Microsoft Office Picture Manager. From the Start menu -> All Programs -> Microsoft Office -> Microsoft Office Tools

or, if it's not there then in this location for Office 2003:

C:\Program Files\Microsoft Office\OFFICE11\OIS.EXE

I'm not sure about doing it without losing quality but you can easily, shrink, compress, resize etc. photos in bulk. PNG is a good format for publishing to the web, and compressing. I prefer it to JPG.

Take a look, chances are you have the software all ready. Microsoft is fairly ubiquitous!

Irfanview is good, you will need a plugin aswell as the main download


IrfanView - Official Homepage - one of the most popular viewers worldwide

mspaint ( on windows ) or gimp ?

MSPAINT?!?! doesn't that restrict you to one image at a time, and default to bitmap?

There's an image compression app in PowerToys. But it's not as good as Photoshop's Save for Web.

ImageMagick: Convert, Edit, and Compose Images

For batch processing... its the daddy.

For the special case of PNG
PNGCRUSH

Or particularly jpegs...

+1 for Irfanview. Not sure what plugin is needed though we just use it out of the box.

The tools mentioned all do the job of batch resizing images on your local computer but AFAIK there is no solution of resizing the images already present on your webserver (unless you've got total control over it and can treat it like a local server).


If I have time - I download the image files using FTP down to a local folder, resize them (I just use MS Imageresizer and use options of resize to 640x480, in place and don't resize smaller images )

I then FTP them back up (which takes a lot less time than downloading them )

I try to educate the teachers to use resize before they upload and knobble school cameras to produce smaller images but its an uphill battle
