Image to PDF Converter

Image to PDF Converter is an online image to PDF converter that helps you combine multiple images into one clean PDF file directly in your browser. It is suitable for everyday needs such as JPG to PDF, PNG to PDF, scanned document collation, and submission-ready file packaging.

Compared with many traditional converters, this tool gives you practical layout controls during conversion, including page size presets, custom page size, image scale, and linked or independent margins, so you can generate print-ready or archive-ready PDFs with fewer adjustments.

Core Features

• Convert multiple images into a single PDF in one run.
• Accept common formats such as JPG, JPEG, PNG, WebP, GIF, BMP, TIFF, AVIF, HEIC, HEIF, SVG, and ICO (subject to browser decoding support).
• Choose page size quickly with presets like A4, Letter, Legal, and A3, or set a fully custom size.
• Control page layout with image scale and margins.
• Link all margins with one value or adjust top/right/bottom/left separately.
• Process files locally in the browser for faster iteration and better privacy.

How to Use

1. Upload one or more image files.
2. In Page size, choose:
   • Auto to match each image size, or
   • A preset size (A4, Letter, Legal, A3), or
   • Custom and enter width/height in millimeters.
3. Set Image scale if you want a larger or smaller placed image before fitting.
4. Configure Margins:
   • Enable Link all margins for unified spacing, or
   • Disable it to set each side independently.
5. Click Convert to PDF.
6. Download the generated PDF file.

Parameter Guide

Image Scale

• Defines the source image scaling before layout fitting.
• Higher values can improve effective page coverage for small inputs, while very high values may increase processing time.

Page Size

• Auto: each page follows the corresponding image dimensions.
• Preset sizes: fast standard output for office and print workflows.
• Custom: manual width and height in mm for specialized templates.

Margins

• Margins are set in millimeters.
• Linked margins are recommended for consistent document appearance.
• Independent margins are useful for binding offsets and asymmetric print layout.

Practical Scenarios

• Prepare a portfolio PDF from product screenshots and design previews.
• Merge photographed invoices and receipts into one submission file.
• Convert mixed image exports into a standardized Letter or A4 PDF for team review.

Best Practices

• Use Auto when images have mixed orientations and dimensions.
• Use A4 or Letter presets for printing and formal submission.
• Keep moderate margins to avoid clipping near page edges.
• If a specific image fails to convert, re-export it as JPG or PNG and retry.

Notes

• Supported upload formats depend on your browser’s decoding capabilities.
• Very large batches or high-resolution images can take longer to process.
• If one image cannot be decoded, conversion may fail for the current run.
