Remove white background in png files without photoshop?

Just wondering if anyone knows any online tool/small free program that might help me to remove the white background and make the background transparent for a .png file? Nope it is not for stealing images :)

  • If you want a photoshop alternative which is free, try GIMP.

    If it's just one image, post it here, and we can do it for you.

    This is something you can't really do accurately in an automated fashion. GIMP is actually very suitable for this task - select magic wand, set the right tolerance (trial and error) and start selecting and deleting. That's pretty much all there is to it. Then save as PNG.

  • Additionally, GIMP now supports single-window mode, so you don't get a mass of floating windows anymore.

    I doubt it. At best, you could have used ImageMagick or GD to change all white pixels to transparent pixels.

    That does not account for:

    1. White pixels that are actually part of the image, and not of the background.
    2. Pixels that are almost white but not quite (while being part of the background).
    3. Alpha channel oddness, such as a 'glow' or 'shadow' around an element, where the pixels aren't white, yet should be semi-transparent to avoid a ragged edge.

    There may be a way of doing this in ImageMagick at the command line, but I don't have time/inclination to research...just throwing it out as an idea.

  • Gimp ^^

  • I just noticed that I actually have paint.net installed on my laptop, does anyone know what is the correct procedure to remove the white background in Paint.NET?

  • why don't you pm @AsadHaider? he willing to help you

  • @Randy said: why don't you pm @AsadHaider? he willing to help you

    He actually did, thanks so much to him but I guess it is better for me to learn how to catch fish rather than get fish from someone every time I am hungry :)

  • So nobody knows how to do it in Paint.NET? Just for my own learning purposes and so that I don't have to bug @AsadHaider every time :) Thanks people!

    Have not experimented yet, will try it at home tonight.

    Gimp is good

  • Paint.NET is just like an upgraded version of Microsoft Paint that has some UI elements of Photoshop adapted to it.

    Better use Photoshop or GIMP :)
