Batch JPG to PDF Converter — Merge Multiple Images into One PDF
What it does
- Combines multiple JPG/JPEG images into a single PDF file, preserving image order and basic layout.
Key features
- Batch processing: Add many images at once.
- Ordering: Rearrange images before merging.
- Output options: Choose page size (A4, Letter, custom), orientation (portrait/landscape), margins, and image scaling (fit, fill, actual size).
- Quality settings: Adjust image compression to reduce PDF size or preserve resolution.
- File naming & metadata: Set output filename and optionally add title/author.
- Security (optional): Add password protection and basic permissions.
- Preview & reorder: Thumbnail preview to check sequence and orientation.
- Speed & offline use: Desktop apps offer faster, offline processing; web tools provide convenience without installation.
Typical workflow
- Open the converter and choose “Add files” or drag-and-drop JPGs.
- Reorder images as needed (drag thumbnails).
- Select page size, orientation, margins, and scaling.
- Choose image quality/compression and optional security settings.
- Click “Merge” or “Convert” and save the resulting PDF.
When to use
- Creating photo albums, receipts, scanned documents, or multipage portfolios from separate images.
- Preparing image-based PDFs for sharing, printing, or archiving.
Tips
- Rotate images beforehand if orientation matters; many converters can rotate during import.
- For searchable PDFs (text extraction), use OCR-enabled tools after merging or convert from original scans through an OCR-capable app.
- If file size matters, lower image quality or enable higher compression; for print, keep resolution high.
Limitations
- Resulting PDFs are typically image-based and not text-searchable unless OCR is applied.
- Very large batches may produce large PDFs or require more RAM in desktop apps.
