How it works

Convert images to PDF online

The “Convert images to PDF online” workflow consists of 3 consecutive stages. Review the settings and expected output at each stage because processing creates a new copy instead of overwriting the source.

  1. 01Upload file

    Upload one or more JPG or PNG images here.

  2. 02Choose settings

    Choose the settings and review the expected result before processing.

  3. 03Get the result

    Download a separate result without changing the source file.

What you can do

The capabilities below describe what is included in the workflow and the resulting file. Use them to confirm whether this tool completes the task or whether another processing stage will be needed.

  • JPG and PNG
  • EXIF orientation
  • Reordering
  • A4, Letter or auto size

Limits and important details

Limits keep the result predictable by describing supported files, processing boundaries and PDF properties that may require manual review. Read them before starting, especially for complex documents.

  • A separate output is created; the source PDF remains unchanged
  • PDFs are not stored in a permanent document library
  • An inactive guest session expires after 15 minutes
  • The hard session limit is 2 hours

Before you start

  • Keep the source file until the result has been reviewed
  • Check whether the PDF is password-protected or digitally signed
  • Identify the pages and objects that are expected to change
  • Use a non-sensitive test copy for an unfamiliar workflow

Result checklist

  • Open the downloaded copy in a second PDF viewer
  • Review every changed page at normal and enlarged zoom
  • Check text search, links, forms and visual quality where relevant
  • Confirm that confidential data and metadata meet the intended use
