Optimization
File Size & Compression
Automatically optimize and compress high-resolution images within your HTML before generating the PDF, dramatically shrinking the final file size without noticeable quality loss.
Up to 80% Size Reduction
Zero Client CPU Usage
Implementation Example
{
"url": "https://example.com/heavy-images",
// Compress image quality to 60%
"image_compression_quality": 60,
// Resize any image wider than 800px down to 800px
"image_compression_width": 800
}
Parameters Explained
Our powerful server-side algorithms intercept image loading, applying dynamic resizing and native format-preserving compression (JPEG/PNG/WebP) directly in-memory before the PDF is compiled.
image_compression_quality
Set a value between
1 and 100. Lower values aggressively compress images to reduce size. We recommend 60-80 for a good balance of size vs quality.
image_compression_width
Set a max width in pixels (e.g.
1000). Any image wider than this will be proportionally resized down before being embedded into the PDF.
