How can I open a 400MB .png image file? - Page 4

post #31 of 44
There are a few conversion programs that use DOS and the command prompt. I'm not sure if they would have to unpack and repack to convert but they most likely won't un-compress to view which is probably half the battle.

I refer to these but never have used them, so...
Go to google and type 'command prompt picture converter'. I was able to find 2 or 3.

I now the photo editor that I use has a batch editor that allows me to convert it, resize, or use a variety of other editing functions. I use it to create a a jpeg copy of my tiff files so it is easier to view images quickly without trying to load a bunch 80+ MB files.

I'm not sure about GIMP, PAINT.NET or other free to use image editing softwares. But as some have said, in photoshop you have to ability to resize an image without having to open it.

400MB files isn't funny, then one day, i made some 2GB panoramas, then 400MB files are so easy to work with in comparison.

No idea if this can handle something THAT big but it always worked great for me for resizing.

On *nix I use the ImageMagick suite from the command line to resize images in batch and such:

They appear to have a windows binary available.
worth a shot, imo

If you have access to a Linux machine, ImageMagick's convert tool is probably your best bet.
