Issues with PDF File Size for Mod Downloads on My Website

[fr_legends_1008]

Hello Adobe Community,

I run a website focused on FR Legends mods where I occasionally share downloadable PDFs with guides and instructions. I've been having trouble with PDF file sizes—some of the guides include high-resolution images of car models and other visuals, which makes the files quite large. This impacts the download speed and can be frustrating for users.

I've tried compressing the files using Acrobat's built-in tools, but I often lose quality, especially in the images. Are there any specific settings or workflows in Acrobat to reduce file size without sacrificing too much image quality? Any tips for balancing file size and image clarity would be greatly appreciated.

Thank you.

Hi @fr_legends_1008,

Hope you are doing well. Thanks for writing in!

In case you are still looking for a solution, you can try the methods below that can help you reduce file size while preserving as much image clarity as possible:

Use PDF Optimizer in Acrobat:

• In Acrobat Pro, go to File > Save as Other > Optimized PDF. This tool gives you more control over what gets compressed.

• Click on Audit space usage to see what’s contributing to the file size (images, fonts, etc.). You can target specific areas to optimize.

• Under the Images section, you can adjust settings for compression (e.g., downsampling) without sacrificing too much quality:
  
  
  • Set the resolution to around 150 dpi for images that don't need ultra-high resolution. This usually provides a good balance for web use.
  
  
  • Choose JPEG compression with Medium quality or Automatic for best results.

Downsampling Images:

• In the PDF Optimizer settings, you can downsample images to a lower resolution while controlling the quality. For images like car models, you can try reducing them to around 150-200 dpi for web viewing, which can significantly reduce file size without a huge drop in visible quality.

• Use Bicubic Downsampling to maintain better visual quality compared to other methods.

Hope this helps.
