Image To PDF Plus: Step-by-Step Guide to Create High-Quality PDFs

Image To PDF Plus: Step-by-Step Guide to Create High-Quality PDFsImage To PDF Plus is a versatile tool for converting photographs, scans, and other image files into clean, shareable PDF documents. This guide walks you through preparing images, converting them with Image To PDF Plus, optimizing output quality and size, and troubleshooting common issues so your PDFs look professional on any device.

Why choose Image To PDF Plus?

• Easy batch conversion — Convert many images into a single PDF in one go.
• Multiple input formats — Supports JPEG, PNG, TIFF, BMP, and more.
• Quality and size controls — Adjust resolution, compression, and page layout.
• Simple interface — Designed for users of all levels, from beginners to power users.

Before you start: prepare your images

1. Organize files
   • Put images in a single folder and name them in the order you want them to appear (e.g., 01_front.jpg, 02_page.jpg).
2. Check orientation and rotation
   • Rotate images so text and important content read correctly.
3. Crop and remove borders (optional)
   • Crop out unwanted margins or background to make pages look cleaner.
4. Fix exposure and contrast (optional)
   • For photographed documents, adjust brightness/contrast and straighten skewed pages for better OCR and readability.
5. Choose color vs. grayscale
   • Use color for photos or graphics; choose grayscale or black-and-white for text-only documents to reduce file size.

Step-by-step conversion

1. Launch Image To PDF Plus
   • Open the application on your device (desktop or mobile).
2. Create a new project or conversion task
   • Choose “New” or “Add Files” depending on the interface.
3. Add your images
   • Drag-and-drop the prepared images or use the file picker. Verify the order; reorder if necessary.
4. Configure page settings
   • Select page size (A4, Letter, Custom), orientation (Portrait/Landscape), and margins.
5. Set image scaling and alignment
   • Choose “Fit to page” or “Keep original size.” For documents, “Fit to page” generally improves consistency.
6. Choose output quality and compression
   • For high-quality PDFs, select a higher DPI (300 DPI or more) and lower compression. If file size matters, choose medium compression or convert to grayscale.
7. Enable OCR (if available and needed)
   • Turn on OCR to make text selectable and searchable. Select the correct language for best results.
8. Add metadata (optional)
   • Fill title, author, subject, and keywords to improve searchability.
9. Preview the PDF
   • Use the built-in preview to check page order, cropping, and image quality.
10. Export or save as PDF
    • Choose the output folder and filename, then click “Convert” or “Save.” Wait for processing to finish.

Optimizing for quality and size

• DPI recommendations:
  • Text documents: 300 DPI for archiving or printing.
  • Photographs: 300–600 DPI depending on desired clarity.
• Compression tips:
  • Use JPEG compression for photos; use lossless for diagrams or images with text to avoid artifacts.
• Color space:
  • RGB for screen use, CMYK for professional printing. Converting color images to grayscale reduces size.
• Combine image preprocessing and app settings:
  • Pre-crop, straighten, and adjust contrast before conversion to reduce reliance on high DPI for legibility.

Using OCR effectively

• Choose the correct language and enable layout detection if available.
• Clean, high-contrast scans yield the best OCR results.
• Proofread OCR results—automatic recognition may misread fonts, handwriting, or faint text.
• Export searchable PDF to enable text selection, copy/paste, and full-text search within the PDF.

Troubleshooting common issues

• Blurry output: increase DPI or improve source image focus.
• Large file size: reduce DPI, switch to grayscale, or increase compression.
• Wrong page order: rename files with numeric prefixes before adding or reorder within the app.
• OCR errors: improve image contrast, rotate correctly, or retry with a different OCR language.
• Missing fonts when printing: embed fonts when exporting (if the app provides that option) or flatten the PDF.

Advanced tips

• Create templates for recurring tasks (e.g., invoices, receipts) with fixed page size and compression settings.
• Use layered PDFs only when necessary; flatten pages to ensure consistent rendering across readers.
• Automate batch conversions with scripts or built-in batch-processing features for large workloads.
• For legal or archival needs, follow PDF/A standards—Image To PDF Plus may offer PDF/A export for long-term preservation.

Example workflows

• Quick mobile scan: photograph pages, auto-crop and auto-enhance, enable OCR, export with medium compression for sharing.
• Archival scan: high-res photos or scanner at 300–600 DPI, lossless compression, PDF/A export, embed metadata and fonts.
• Photo album: keep color, lower compression only slightly to preserve detail, set page size to match image aspect ratio.

Final checklist before sharing

• Verify page order and orientation.
• Confirm OCR accuracy if text search is needed.
• Check file size vs. recipient limits (email, upload platforms).
• Add metadata and password protection if privacy required.

Image To PDF Plus streamlines turning images into polished PDFs whether you’re creating archives, sharing documents, or preparing prints. Follow these steps and tips to get reliable, high-quality results every time.
