Common Use Cases

Scanned Documents

You took photos of a document with your phone. Now you need to submit it as a PDF:

  1. Take clear, well-lit photos of each page
  2. Drop them into our Image to PDF tool
  3. Reorder if needed
  4. Download as a single PDF

Tips for scanning with your phone:

  • Use good lighting (natural daylight is best)
  • Keep the camera straight above the document (avoid angles)
  • Include all edges of the document in the frame
  • Use the phone's built-in document scanner if available (iPhone: Notes app, Android: Google Drive)

Job Applications

Many application portals only accept PDF. If you have JPG certificates, transcripts, or ID scans:

  1. Gather all images
  2. Convert to one combined PDF
  3. Upload the single file

Photo Albums / Portfolios

Create a PDF photo album to share or print:

  1. Drop all photos
  2. Arrange in the order you want
  3. Set page size and margins
  4. Download — ready to print or share

Receipts and Expenses

Photograph receipts and combine them into a PDF for expense reports or tax records.

Image Format Tips

Format From Notes
JPG Phone photos, downloads Most common, works everywhere
PNG Screenshots, graphics Larger files, preserves quality
HEIC iPhone photos Convert to JPG first, then to PDF
WebP Web downloads Convert to PNG first using WebP to PNG

Reducing PDF File Size

If your PDF is too large (common with high-resolution photos):

  • Resize images first using our Image Resizer — resize to 1200-1500px wide before converting
  • Use JPG instead of PNG — photos in JPG are 5-10x smaller
  • Lower photo quality — 80% quality is visually identical to 100% but much smaller
  • Optimal resolution for documents: 200-300 DPI is enough for readable text

Multiple Images → One PDF vs Separate PDFs

Approach When to Use
One combined PDF Job applications, submissions, sharing a document set
Separate PDFs When each image is a standalone document
Split later Combine first, then use PDF Split & Merge to extract pages if needed

Frequently Asked Questions

What is the maximum number of images? Our tool can handle dozens of images. For very large sets (100+), performance depends on your device.

Can I set the page orientation? Yes — rotate individual images in the tool, or choose "Fit to image" page size which automatically matches each image's orientation.

Will the PDF maintain image quality? Yes — images are embedded at their original resolution. The PDF file size depends on the image sizes and format.

Can I add text to the PDF? Our image-to-PDF tool converts images only. For adding text, use a PDF editor after conversion.
