Combine JPG, PNG, WEBP into one PDF
Receipts, site photos, and scanned IDs are easier to archive as a single PDF than a folder of images. RatPDF orders files as uploaded and avoids trailing blank pages.
Tips
- Rename files with numeric prefixes (01-, 02-) before upload for sort order.
- For heavy photo packs, compress the resulting PDF.
- Portrait photos on A4 — expect margins; crop in an image editor first if needed.
