White lines after saving in png

I know this is suuuuuper late, but I'm posting this for anyone else who has had the same question.

I just had the same problem, and I found that if your using Adobe Illustrator, and you select your layer, then go to the asset export button (which I have on the sidelines, but you can access it by doing Window>Asset Export). From there, I just chose png as my file type and exported. It looks really clear on a website i did and the white lines are gone 🙂

I had the same problem with a PNG logo that showed no white line in CS6, but did when I uploaded the PNG to a website. Drove me nuts for a while.

Here's what worked for me:

Go to File > Save for Web and Devices...

In the control panel that opens, look at the color table.You'll see a row of tiles representing the colors in your image. If you see a white tile, highlight it and then hit the Trash icon beneath. When you save your image, anything white should be gone.

Check the 2 saved images flipped against each other, sometimes this is a display driver issue, since you mention that it's not visible in CS6.  Uncheck this setting in your version of PS CC

This can be explained if the file was resized  with layers/masks/selections still present - then flattened and saved out to PNG.

The technical explanation for this is pretty complicated and involves blurring of mask edges in the downsampling, gamma encoding of the mask, and so on.

The bottom line is that you should always flatten first, then resize. Could that be it?

Maybe it's anty-aliasing?

Maybe your object was cut from background before and it's not perfect done?

I assume you saved this file as a psd before saving as png.

Look at this area in each of the separate layers in the psd and see whether it appears.

Are you seeing the lines only in photoshop or after it is saved in another program?
