When I save a pdf logo as jpg in photoshop, it saves it with a white backround

Hi,

I am looking to convert a pdf logo on photoshop to jpg to reduce the file size for speed optimization.

When I add the png logo image to a transparent page on photoshop and then save it as a jpg, it saves it but with a white backround.

How can I save this with the same original transparent backround?

Thank you in advance!

Carlos

    A white background makes almost no difference to size, it compresses to almost nothing.

    But my first thought is that the size of these graphics (1024 x 1024) is huge for a button. It is fine for a graphic that dominates the entire page, but what size are these graphics run, on the page, in pixels ("live size")? You should probably produce them at their live size (or multiple copies for different live sizes). The web customer should not be paying to download and subsample...

    You can reduce the file size much further.

    • Original PNG (32bit): 123KB
    • Optimised PNG (32bit): 99KB
    • GIF (256 colours): 57KB
    • JPEG (Quality 10): 40KB
    • PNG (256 colours): 36KB

    All without too much quality compromises.

    There is no transparency in jpg.

    Anyway you seem to mix formats – is the logo pdf or png?

    In the case of pdf it may be vector and would suffer in any pixel format.

    Thank you c.pfaffenbichler,

    The logo is png as you mention, sorry.

    So if i understand correctly there is no way to convert a png logo to a jpg and maintain the transparency?

    Thank you!

    Hi Carlos,

    JPEG does not support transparency. It will fill in transparent areas with white.
