Key Features of the RiazHub Image to PDF Tool
1. Advanced PDF Page Size Controls & Custom Dimensions
Every project has unique formatting requirements. With the RiazHub Image to PDF Tool, you aren’t restricted to default page dimensions. Select from popular presets like A4 (210 × 297 mm) or US Letter (8.5 × 11 in), choose Fit Image Dimensions to let each page match your photo’s exact proportions, or select Custom Page Size to specify custom width and height values in mm, in, or px.
2. Smart Page Orientation & Margin Spacing
Set orientation to Auto to let the converter automatically detect portrait vs. landscape images for optimal page display, or force all pages to Portrait or Landscape. Customize spacing with No Margin (0 mm), Small Margin (10 mm), or Large Margin (20 mm) options.
3. Multi-Image Grid Mode
Need to fit multiple photos onto a single sheet of paper? Switch the Image Layout setting from 1 Image per Page to Grid Mode (2×2 per Page) to automatically arrange four images per sheet—ideal for printing contact sheets, flashcards, or photo catalogs while saving paper.
4. Drag & Drop Reordering & 90° Rotation
Adjusting the page sequence in your final PDF is simple. Drag and drop any image card in the interactive gallery grid, or use the quick Move Left/Up and Move Right/Down arrow buttons. If an image is shot sideways, click the rotate button on that card to turn it 90° clockwise, or use the “Rotate All 90°” button to rotate the entire sequence at once.

Browser-Based Conversion: Why Privacy Matters
Many online file converters process your images on external servers, exposing confidential documents, contracts, identity cards, or private family photographs to security vulnerabilities. By utilizing Web API FileReader and HTML5 Canvas engines, our Privacy-First Image to PDF Converter processes every single byte locally within your browser tab. Your files remain 100% confidential and secure.
