Question

PDF files display differently in Acrobat than in browser viewers

Hi everyone,

I'm running into an issue with some PDF files that I upload for visitors on my website, [third party link removed by Adobe Moderator]

When I open the PDFs in Adobe Acrobat, everything looks correct, including fonts, spacing, and formatting. However, when the same files are opened in browser-based PDF viewers, some text appears slightly different and a few elements shift position.

I've already tried re-exporting the PDFs and embedding fonts where possible, but the issue still occurs on certain devices and browsers.

Is there a recommended Acrobat export setting or compatibility option that helps ensure PDFs render more consistently across different viewers?

Any advice would be appreciated. Thanks!

    Hello @Emilycarter,


    I hope you are doing well, and thanks for reaching out. We're sorry for the trouble you had.


    Please note that all browsers have their own capability to render PDF and its content. Browser PDF viewers implement only a subset of the PDF specification so that they can render the same file differently from full Acrobat.


    Suggestions:

    Open one of the affected PDFs in Acrobat and check:

    1. Menu (hamburger) > Document Properties > Fonts tab. Every font your document uses should show Embedded or Embedded Subset beside it. If any font has neither tag, or if a font you expect to see isn't listed at all, that's the substitution gap browsers are exposing. Subset embedding is fine; non-embedded fonts are the problem.

    2. Go to Menu > Save as Other > Optimized PDF (on macOS: Acrobat > Save as Other > Optimized PDF).

    3. In the dialog, select Fonts in the left pane. Move any unembedded font from the right list to the left list using the arrow buttons (or use the Embed action). If you want to keep all existing embeds intact, tick Do not unembed any font under Font Unembedding Settings.

    4. In Make compatible with, choose Acrobat 7.0 and later (PDF 1.6) or Acrobat 8.0 and later (PDF 1.7).

    5. In Clean Up, ensure Optimize the PDF for fast web view is selected.

    6. Click OK, save with a new filename


    If you have Acrobat, please use the Preflight tool to embed missing fonts. Check this article for more details: https://adobe.ly/3PCZ6fQ

    I hope this helps, and let us know how it goes.

    Regards,

    Anand Sri.
