How to Convert Multiple Images (JPG, PNG, HEIC) into One PDF

To combine JPG, PNG, or HEIC images into a single PDF, use Zro7 Images to PDF. Drop as many images as you want, drag to reorder, pick a page size (A4, Letter, or fit-to-image), and download one clean PDF. Everything happens in your browser — ideal for expense receipts, ID scans, and anything else you'd rather not upload.

Why one PDF beats a folder of JPGs

• Reviewers open one file, not ten. Expense systems, insurance forms, and legal packets expect a single document.
• Order is preserved. ZIP a folder and the recipient sees whatever alphabetical order their OS invents.
• Smaller than a ZIP when images are re-encoded to JPEG at a sensible quality.
• Printable. One PDF, one print job, correct page order.

HEIC handled without a converter step

iPhone photos default to HEIC, which most PDF creators can't ingest. Zro7 decodes HEIC in the browser via WebAssembly, so you can drop iPhone photos directly. If you want plain JPGs first, use HEIC to JPG.

Steps

1. Open Images to PDF.
2. Drop images — JPG, PNG, WebP, HEIC all welcome.
3. Drag thumbnails to reorder; rotate any that were shot sideways.
4. Pick page size (A4 / Letter / fit-to-image) and orientation.
5. Optionally re-compress JPEGs to shrink the file.
6. Click Create PDF and download.

Sensible defaults

• Receipts / documents: A4 portrait, JPEG quality 80.
• Photo album: fit-to-image, quality 90.
• Scanned pages: A4 portrait, keep original resolution (don't recompress crisp scans).
