Photo Compression

[hariharan]

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

^^ hey, thanx for this, even i was looking for sumthing like this Picasa..as even i was relying on the old MS Paint..but it was a really tedious task..

Will the Picasa convert all the pics at one go ?? or will i hv to go it one-by-one for every single pic ??

Cheers n e-peace...

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.

hey thanx alot lot for the reply buddy.. really appreciate it, will try out the s/w from *ahem...* sources..

[dpuk]

^^ let me suggest you the best source -----------> Google!!!
yeah, right, it's FREEE!!!

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

[ashu888ashu888]

^^ ooh, good then, will try out that too... i guess its a freeware...

[dpuk]

dude even PICASSA is a freeware....download it.

[hjpotter92]

picasa is a freeware, but it takes a lot of memory.

[hariharan]

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?

[techking_dinesh]

i haven`t read other replies

just dload vso image resizer and size will come down to 200-250kb per photo and quality will be same

for more support contact me at yahoo messenger: id : great_dindi

^^ thanks

irfan view too can resize without much ado. digit oct issue has included a small explanatory workshop too.

[hjpotter92]

Yeppp, thats wat I was going to put now....

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.

But the size is gigantic

7.8 MB is gigantic???
guess you are on dial up.

Anyways, how does Adobe Photoshop Album compare to lightroom or adobe photoshop elements (only the organiser part, editing is not required)

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.

Not the dnload size, but the memory size...

[Cool Buddy]

oops, sorry.
any views about the softwares organising capabilities?

[tech_creeds]

hi frends......
dont forget to check out fotosizer its a good piece of software with batch convertion feature. its interface too is very good just try it ,its freeware

[Rahim]

Picasa is confusing and it raids my hard drives without asking me!!

[thewisecrab]

Irfanview should do the trick

[mmharshaa]

If u have an ocean of patience you can do this one...

Open each photo in mspaint and save it as .jpg

This will reduce each file to about 500 kb

If there is any other way to change the format of all the files at once u can try that...

[maindola]

Step1: Open Irfan View, Press S for "Save as" to save the file in desired format (Jpeg in case its a RAW format).

Step 2: Use Cntrl+R to resize the file to desired size.

This should reduce the size to a great extent.

Buddy you need XAT Image optimizer
Its a powerful tool for image optimization, that not only includes loss less compression, but various other utilities (like adding text, watermarks or correcting tilt error etc). Support batch conversion as well. Very handy tool. Have been using this for ages...

[MenTaLLyMenTaL]

+1 IrfanView! Really lightweight - filesize and memory and lots of options.

[NucleusKore]

You can use The GIMP.

[hjpotter92]

GIMP isn't user friendly. Open IView, press 'B' and go to the extents of conversion, renaming.... and the lot.

Technically speaking, there has been loss of quality as it is a JPEG file.

I think you've used MsPaint and saved it again, Paint has compressed it more and there *has* been loss of quality, but you can't actually observe it as it is a photograph taken through a camera of physical sorroundings. It has got millions of pixels of different colours, it makes the loss very difficult to observe.

If you will, try saving a BITMAP file drawn by a child to JPEG file through Photoshop & GIMP, they'll give you options of various compressing levels ranging from 1-10 and you'll be able to observe the loss of quality & the quality difference in 2 JPEG files compressed at different levels. JPEG is lossy compression.
