Converting JPG images into a single PDF is one of the most practical document tasks you'll encounter. Whether you've scanned a multi-page contract on your phone, photographed a series of handwritten notes, collected product images for a catalogue, or compiled screenshots into a report — combining multiple JPG files into one PDF makes them easier to share, archive and present professionally.

Why Convert JPG to PDF?

A PDF is universally readable, maintains your layout regardless of device, and bundles multiple pages into a single file that's easy to email, upload and print. Sending 20 separate JPG files is inconvenient for everyone. Sending one PDF keeps everything together and makes the right impression in professional contexts.

  • Scanned documents: Combine scanned pages from a contract, application or form into one organised PDF
  • Photography proofs: Bundle client photos into a PDF for review and approval
  • Reports and portfolios: Assemble design mockups, data charts and screenshots into a shareable report
  • Medical and official documents: Combine scanned ID pages, insurance cards or medical forms into one submission file
  • Receipts and invoices: Merge multiple expense receipt photos into one PDF for accounting or reimbursement

Page Size Options Explained

  • Keep original size: Each image becomes a PDF page at its exact pixel dimensions. Use this when precise sizing doesn't matter and you want the highest fidelity to the original image.
  • Fit to A4: Images are scaled to fit within standard A4 dimensions (210 × 297mm). Use this for documents destined for European printing, official submissions or anywhere A4 is the expected standard.
  • Fit to US Letter: Scales to 8.5 × 11 inches — the standard page size in the United States. Use for business documents, HR submissions and anything destined for US office printing.

Images are never upscaled beyond their original resolution — only downscaled when they exceed the target page size. This ensures maximum quality with no artificial sharpness loss.

Page Order

Images appear in your PDF in the exact order they were selected during upload. To control the page sequence, select your files in the order you want them to appear, or use your file manager to name them sequentially (001.jpg, 002.jpg, etc.) before selecting them all at once.

Preparing Your Images Before Converting

For the best PDF results, take a moment to prepare your images first:

  • Use Image Rotator to fix any sideways or upside-down photos before creating the PDF
  • Use Image Resizer to standardise dimensions if your images are from different sources and different sizes
  • Use Image Compressor to reduce JPG file sizes before creating the PDF, especially if you have many high-resolution photos
