CALCIXA PRACTICAL GUIDE

How to use the Image to PDF Converter

The image-to-PDF tool arranges selected images as pages in a downloadable PDF. It is useful for combining scans, receipts, or photos in a chosen order without transferring the files to Calcixa.

A PDF made from photographs is not automatically searchable or accessible. Page size, orientation, margins, image resolution, and source rotation affect readability and output size; sensitive documents should be reviewed before sharing.

Step-by-step

  1. Select supported images and review their filenames.
  2. Reorder pages and choose page size, orientation, and margins.
  3. Generate the PDF and inspect every page.
  4. Download with a descriptive filename and add OCR or accessibility tags in a specialized tool if required.

How to read the result

  • Each selected image becomes a page in the chosen order.
  • Images may be scaled to fit while preserving proportions.
  • Output size reflects source resolution, image count, and encoding.

Common mistakes to avoid

  • Creating sideways or out-of-order pages.
  • Assuming image text is selectable text.
  • Sharing a document before checking cropped edges and sensitive details.

Important: Review important outputs before relying on them in a production, legal, or safety-critical workflow.

More questions about Image to PDF Converter

Are my documents sent to a server?

No. PDF creation runs in the browser with the bundled processing library.

Will the PDF contain OCR?

No. The page contains an image unless the source or another tool adds a text layer.

Why is the PDF large?

High-resolution images and many pages can make image-based PDFs large.
