I have too many photos ( about 27 GB ) of them taken from my digi cam. These photos were taken with 7MP resolution and the size of each photo is about 3 -3.5 MB. Now i need to compress them without loss in quality.
I tried opening the photos and saving them in the same format, the photo size reduces ( it came down to abt 600KB), but I could not see any perceptible change in the quality. What exactly is happening here? I saw all the parameters of the photo in its property file were unchanged.
Is there any good free photo / image compressor that would do the job for me easily. I want the photos to retain the same resolution and the format, but reduction in size.
Suggest the best possible solution. Thanks

Picasa is a great application Ashu...
It will convert all you pics folderwise...you can convert all the pics at once....no hassles, no problems at all.....you can keep the original ones as well as the picasa's.
I'm using it and I've converted around 2-3Gb photos tu put in my cellphone...it works just fine....you can choose quality settings, the size and there are also editing options.

You can also use Irfan View. It also has the ability to rename the files accordingly. And it has advanced features tooo.

I use Picasa for Photo Management in my desktop. I would try out the photo compression feature.

But what I don't understand is Picasa compresses the picture by reduction in resolution. What MSPAINT does is, reduction in image size without reduction in resolution. Still 3xxx by 2xxx is retained, but size is reduced drastically. How is this possible.

Is it possible to do the same all at one go for an entire folder using Picasa / Irfanivew / any other freeware?

Batch conversion software don't generally come bundled with the camera?

I got my copy of Adobe Photoshop Album (Starter Edition) with one! Also, it is free to download from Adobe's site as well. :)

Pictures are usually saved in RAW format within the camera which have a lot of picture details and thus needs more space. While compression softwares efficiently reduces picture size removing those details in a way such that minute deterioration takes place in terms of picture quality. JPEG is a widely used compressed format.
