How to Improve Image Quality When Converting a URL to PDF in Adobe Acrobat
Question details
Users need a way to preserve the original high resolution of JPG and PNG files when generating a PDF document directly from a webpage URL.
- Product
- Adobe Acrobat Pro DC
- Device & OS
- not provided
- Scenario
- Creating a PDF from a webpage URL resulting in degraded image quality.
- Observed behavior
- Images embedded in the resulting PDF appear lower in quality than the source files on the webpage because the conversion relies on Acrobat's default Standard compression settings.
Before modifying Acrobat's core job settings, ensure you back up your original 'Standard.joboptions' file, as future software updates might overwrite your customized configurations.
Modify the Standard.joboptions Downsampling and Compression Settings
Adjust the default job options used by HTML and Outlook PDFMaker conversions to prevent Acrobat from heavily compressing or downsampling images.
By default, Adobe Acrobat uses 'Standard.joboptions' for generating PDFs from webpages. This preset is optimized to keep file sizes small, which significantly degrades image quality. Editing this preset ensures original media quality is maintained.
Open Adobe Acrobat Pro DC, go to 'Edit' > 'Preflight' (or access Distiller settings) to find the 'Standard' profile.
Edit the profile's 'Images' settings. Change the downsampling threshold to avoid downsampling images below approximately 450 dpi.
Under the compression options, select 'Automatic (JPEG)' compression and set the image quality to 'Maximum' rather than the default Medium/Low.
Navigate to the 'Fonts' tab and ensure fonts are embedded as subsets. Under the 'Color' tab, select the option to leave colors unchanged to avoid unnecessary color conversion.
Save this customized profile and restart Acrobat. Future URL to PDF conversions will now utilize these high-quality settings.

Frequently Asked Questions
Why do images look blurry when saving a webpage as a PDF?
Acrobat defaults to 'Standard' job options designed to minimize PDF file sizes. This preset heavily compresses media and downsamples images (often to 150 dpi or lower), causing JPGs and PNGs to lose their crispness and appear blurry.
How do I stop Acrobat from compressing images when creating PDFs?
You can prevent this by opening Acrobat Preferences, navigating to 'Convert to PDF', and modifying the specific settings for HTML, JPEG, and PNG to use 'Maximum' quality while turning off image downsampling.
Can I recover my original PDF conversion settings in Acrobat?
Yes. If your customized settings cause issues, you can restore the default behavior by selecting the default 'Standard' preset in Acrobat Distiller, or by deleting your modified 'Standard.joboptions' file so Acrobat regenerates the default version.
