Turn images into a PDF document

How it works in FileLume

• Each image is decoded, drawn to a canvas at its natural dimensions, and exported as JPEG quality 0.9.
• pdf-lib creates a PDF page matching the embedded image dimensions and places the image across the page.

Best for

• Combining scans, receipts, photos, or screenshots into a document.
• Creating a PDF accepted by a form or email workflow.
• Turning image evidence into a predictable page sequence.

Format and quality guidance

• The current PDF path embeds JPEG, so transparent source pixels may become a solid background.
• Image-based pages do not contain selectable or searchable text unless OCR is run separately.
• Large source dimensions create large PDF pages and use more browser memory.

Trade-offs to expect

• JPEG encoding can reduce fine detail in screenshots, diagrams, and small text.
• The PDF preserves visual pixels rather than document structure or accessibility information.

Limitations

• The current implementation creates one PDF result per processed image path rather than OCR text.
• Very large images can exceed local memory during canvas and PDF embedding.

Common errors and fixes

Text cannot be selected in the PDF.

The pages are embedded images; use an OCR workflow when searchable text is required.

Transparent areas changed.

The current path embeds JPEG, which has no transparency.

The PDF is too large.

Resize or compress the images before creating the PDF.
