Image to PDF Tips

For Documents and Text

If you are scanning a document, use a high resolution (300 DPI or higher) for crisp, readable text in the PDF.

For Photos

Standard resolution (150 to 200 DPI) is sufficient for photos that will be viewed on screen. Use 300 DPI for print quality.

For Passport and ID Photos

Most government portals accept PDF files. Scan your ID at 300 DPI for clear, readable output.

File Size Considerations

High-resolution images create large PDFs. If file size matters, compress the PDF after converting using our PDF Compressor.

iPhone HEIC to PDF

iPhone photos save in HEIC format by default. Our converter handles HEIC directly — no need to convert to JPG first.

Image to PDF vs Scanning Apps

Mobile scanning apps like CamScanner add perspective correction and enhancement. Our tool is better for:

  • Images already saved on your computer
  • High-quality photos that do not need correction
  • Batch conversion of multiple images at once
