How to adjust (reduce) screen snapshot for sharing

[jetguat]

So must of us know how to take a screen snapshot with the N3. Though I am endless frustrated using the hand swipe technique as i inevitably to impact something within the application that I am trying to take a snapshot of. That said.

The clipboard has the snapshot and you can view it in the gallery. its saved as a .png file. But for some sites the file sizes are two large. What is the method used to reduce the files size. Either via compression, or changing to a new format that can be reduced in size. Is there some capability that is native to do that?

thanks

There are photo editor apps tht can do it (not by compression, a png is already compressed), and there are computer programs that can do it (by copying the image file to the computer, making it smaller, then copying the smller image back to the phone). I use Paint.net for that sort of thing. You should be aware though, that generally "reduce the size" when referring to an image means the same thing as "reduce the quality". You can't keep the same number of pixels and reduce the file size - a file with 10,000 8-bit pixels is 10k. Unless you can find a compression algorithm that's tighter than the one already being used (png is, among other things, a compression algorithm), and doesn't degrade the quality too much (any lossy compression degrades the quality), that file will still be 10k. Unfortunately you're not starting with a raw image, of you could try 7-zip compression to see if the particular picture can compress tighter than png. ("Particular picture", because the amount you can compress a file depends on the data in the file, so remove one flower from a scene and the two pictures will compress differently.)

JPG is the major compressed picture file format.

Inter alia, QuickPic will easily allow you to reduce a picture size [pixels] which is ideal for fast emailing - especially if the image is only ever going to be viewed on another phone.

Edit: OK I just checked and Photo Editor dev.macgyver will let you convert your screenshot .PNG file to a .JPG at whatever compression you want so I started with a 3.14Mb [ie 3140Kb] screenshot image file I had laying about and ended up with a 297Kb JPG picture of it with acceptable quality.

[Technical note, PNG is a lossless format and JPG is a lossy format.]

Here's what to do. Take the pen out. Hold the button on the side as you press down onto the screen you want a screenshot of.
