1. How to Use
- Upload PNG images via drag-and-drop or click to browse. Supports multiple files—they will be combined into one PDF in the order you add them.
- Review the file list. Remove individual files or click Clear All to start over.
- Click Convert to PDF. Each image becomes a separate PDF page sized exactly to its dimensions—no white margins, no aspect ratio distortion.

2. How It Works
Each PNG is loaded to get its naturalWidth and naturalHeight. pdf-lib creates a page with those exact dimensions (in PDF points, 1:1 with pixels).
The image is embedded at (0, 0) with width and height matching the page. Transparency is preserved where supported by PDF.
PNG data is embedded without recompression. Original quality and transparency are preserved.
Multiple images produce a multi-page PDF with varying page sizes.
