I have use Acrobat Pro DC to create fillable form, mainly I use "Adobe Ming Std Light" font. But pdf file size is very large arround 4.2MB. Already try optimized pdf, the file size did not change

In "PDF Optimizer" --> "Audit space usage", it show font size used 4.2M.
In "PDF Optimizer" --> "Fonts" it did not have any embedded fonts.

1. How to reduce files size?
2. Any tools/method can help to reduce size?
3. Need change to other fonts? but the fonts need supported English, Traditional chinese and Simplified chinese

    Correct answer Dov Isaacs

    The font you use for a form must be fully embedded in the PDF file. Asian language fonts are large due to the large number of characters that must by accommodated by such fonts and as a result, your PDF file is large. Due to the embedding requirement, Acrobat's file reduction and optimization capabilities will not un-embed such fonts.

    What’s wrong with the PDF - unless you make the mistake of trying to email it? That should be avoided, big or small...

    Hi dmantse,

    Sorry for the delay in response.

    To check the fonts embedded, open the file in Acrobat> File > Properties > Security (tab). You can check the fonts embedded.

    You may check the steps Optimizing PDFs in Adobe Acrobat Pro I assume you may have already exhausted.

    If you try to use a different font does that make any difference? If you already have found a solution to this problem, you may update this thread with your findings and that will help other users.

    Thanks for your reply.

    I have find "Adobe Ming Std L" font embedded, but no ways to prevent or remove embedded font.

    I have already try Optimizing PDF or change to another font but still failed. It seem it have embeded subset font cannot remove.

    Some PDF I can use Acrobat 9 save once to reduce size but some PDF file cannot .
