Converting images to PDF: tips for the best result
A PDF is the easiest way to send several photos or scanned pages as one document — for applications, expense reports, school assignments or insurance claims. ToolCMB puts your images into a PDF right in your browser, so personal photos and documents are never uploaded.
Choose Same as image if every page should match its photo exactly, or a paper size like A4 or US Letter when the PDF will be printed. “Auto” picks Letter in North America and A4 elsewhere, and turns pages to landscape for wide images.
With Original quality, JPEGs are embedded without being re-compressed, so nothing gets lost. For email or upload portals with size limits choose Smaller file, which scales large photos down to 1600 pixels — still perfectly readable.

Tips
- Scanned receipts? Use 4 images per page with a small margin to save paper.
- iPhone photos in HEIC format? Convert them first with HEIC to JPG (Safari reads HEIC directly).
- PDF still too big? Run it through the PDF Compressor.
- Need images back from a PDF? Use PDF to JPG.
