JPG -> PNG?

[Submeg]

Is there a program which will do it automatically without me having to go through each picture??

@Submeg i don't know about jpeg to png direct conversion but i used infranview to convert all my Amiga .iff images to png for viewing on pc

get it here

it does batch file conversion and even sequential re-naming etc 000, 001,002 etc

hope that helps m8!

Ps i hope you mean Pc of course

Yep all on PC, it's just that having 700 photos in JPEG takes a bit of room when u want to upload

With photos PNG will be far larger! JPG is the most efficient file format when it comes to photos.

Damn it is too! oh well time to upload then!!!

Have you tried just compressing the jpgs more? Normally most pictures will look perfectly fine with a 20-30% compression ratio (that's photoshop settings, some software uses reverse percentages. Basically I'm meaning 20% quality/size of original file). Also reducing the dimensions of an image a bit can dramatically reduce file sizes.

You can easily use irfanview for this. Just experiment with a couple of images to get them smaller while retaining good quality, and then do a batch conversion of the rest using the best settings you worked out.
