Change white background to transparent mac

Very helpful. Just fixed my logo and plan to launch the new version of my web site with an increasing number of Pixelmator enhanced photos soon. Thank you, this is going to be my most used tip! I have done this but when I export it into my blog, the transparent area shows up as white instead of transparent. I saved it as a PNG and told it to keep transparency, what did I do wrong?

Make sure to update your browser to the latest version. Sometime older browsers do like that such as IE6 at my work does the same thing without transparent but white instead.

How to Remove an Image’s Background Using Preview on macOS

Hope that helps! If it does work most likely because the background has many colors or the background and picture wanted to be kept have similar colors. Thanks so much! I used to just try to use the soft eraser and always, painstakingly, attempt to erase all the background on an image. And it was always the worse, especially when I had a person I wanted to erase the background from, and I would get to try to go around his hair, and it was just a huge mess, trying not erase bits of hair, but then it would always leave pieces of the background, between hair locks, just so annoying!!

But this, this, is perfect!!! Oh man, I love Pixelmator so much, and this just reaffirmed my love even more! Thank you so much for this tutorial, and the amazing application that is Pixelmator!!! Went through the tutorials and the help topics-very understandable-have iphoto, picasa, pse, LR, Nikon transfer and view but this app seems to be the the most user friendly and direct with explicit directions.

I have a huge problem doing this. Wish I could just take out the whole background and leave the object……frustrating!!! If the background is a little more complicated than this one, try using other techniques for selecting objects. You might want to have a look at the Lasso Tool tutorial:. I saved as a PNG, it opens in preview fine and has the background now transparent.

I open back in Pixelmator and it is transparent. I than export back to JPG. However the background is now white again? Is it not possible to save a JPG with a transparent background? I am trying to upload to a custom print site and they only allow JPG. Can anyone comment on this? To keep the transparency, you should save your images in PNG file type.

How then could I put in a different background color? I have a picture that I would like to remove the background color which I can use the magic eraser tool above to do that , then I would like to put in another color. How would I do that? Many thanks. Drag this newly created layer below the Background Layer. Torg, yes you can.

Thanks for the tutorial. It looks like it is very easy but when I select my Magic Eraser and place it on my white part of the image it is a large circle and then my entire image goes away and noting is transparent! Clearly I am doing something wrong. Try only clicking.

It should work. If you drag the Tolerance increases and more image is erased. OK, I am missing something. I want to cut away all the background transparent , save the image and import it into a CAD program, so I can overlay the triangle shape over a logo dwg. I erased the background as described above checkerboard pattern , saved it in various formats, but all import into the CAD with a black background filling out the image. Is there a way to get the original image back?

Is there really no way to select non-contiguous areas of the same color? What if the object has holes? Dillo, using selection tools you can choose the selection modes. You can read more about those modes here:. As a Mac user, Pixelmator is my go-to. I used the magic eraser on the top of my image, but now when I click on the bottom portion- like on your picture the bottom portion of the bow, it is not allowing me to use the magic eraser- nothing happens.

What am I doing wrong? The top portion also has a dotted line around the portion I am removing- nothing like that is showing up under the image when I click on it. Thanks for your help!

You made some good points there. I did a search on the issue and found most people will consent with your site. But, what concerning the bottom line? Are you sure about the source? Great tremendous things here. Thank you so much and i am taking a look ahead to contact you. Will you please drop me a mail?

You have used the magic eraser tool here for removing the background and it worked well as the background is in one solid color. But if the background is not in one solid color or the image edge is not plain enough then Photoshop pen tool should be used for image selection and then need remove the background of that image. Most Prominent Work and Tremendous Efforts from you. Fantastic view of points there. If the original file was a PNG or GIF and you are satisfied you can just save as usual, but in a lot of cases you may not want to overwrite the original file. This is demonstrated in an earlier version of Preview where the Editing Tools button was the Pen rather than the modern Toolbox icon, otherwise all else is the same:.

Just remember to look for the Toolbox button in modern Preview versions and the Pen button in earlier Preview releases. Enjoy this tip?

Wow, do you even think about being a bit less of an azzhole when pointing out mistakes? I really love using Preview for all kinds of things Some rudimentary image editing, resizing, merging multiple pictures into one image, combining PDFs, deleting pages from PDFs etc.

Apple Mac Everything

Thanks for telling me about this feature, too! Has apple done it again and removed an interesting feature? I no longer find the instant alpha in Preview Version 7. Every time I export to png, tiff or jpeg, I still get a black background, rather than transparent. Is there some preference I need to set? Also the occasional image.

You can see a little bit of the background image through the foreground of the transparent png. Any idea? Have they removed this feature? Used to be an Apple fan, when it all just worked. Agree with wow comments about simple — thanks to your explanation. The magic wand moved in Preview, but the rest works as described. Huge thanks! Thank you SO much! This was super useful for editing my logo to use for a banner in Canva.
