I'm having issues with artwork I would like to use for my website. Unfortunately, the artwork I have came included with a white background behind it. I realize I can manually remove the white background using tools like the Magic Wand in Photoshop, but I've found that the edges of the artwork lose their sharpness. Is there anyway in Photoshop to just save an image out where the white background is picked up as the part of the artwork that is suppose to be transparent?
I have a trick I developed for this exact situation. You may be best to use slightly different settings for each element you want to be a separate graphic but try the following steps:
- Copy the section you wish to be a graphic into a new file
- Double click on the layer in the layers pallete
- Hold down alt on your keyboard, this separates the handle allowing smooth transparent edges and drag the left half inwards until the white is completely gone. Note: if you're not careful a residue of white may be left.
- You can now save for web as a transparent png if you wish.
See the screenshot below for details of stage 3
As you've mentioned in your question, there are various tools to remove backgrounds from images.
However, there is no automated method to simply designate a color as transparent when saving unless you save as a GIF image. However, GIF would be entirely inappropriate if you have a photograph as opposed to a drawing. Without knowing what the actual image looks like, it's very difficult to recommend the GIF format.
Photoshop cannot determine what the background is, but you can while saving change a color to transparent. For white it will change ALL white, not only "background white". So you'll only be able to use this technique if the object doesn't have white in it.
- Save For Web
- Change it to GIF with the Transparency Ticked
- On left side of the preview window is an eye dropper. Use it to click on the white.
- Click on the transparent box below the color table
- Repeat working closer to the edges until you're satisfied with the results.
