Image to PDF Guide

What this tool is for

This tool allows you to combine several images — like scanned document pages, receipts for tax purposes, or photographs from a project — into a single organized PDF file. PDF is the universal standard for sharing multi-page documents, ensuring that layout and content appear consistently on every device and operating system.

When you should use it

Ideal for submitting multi-page job applications or government forms where multiple photos must be combined into one file, creating digital portfolios with a controlled page layout, organizing expense receipts for accounting, or archiving scanned printed documents into a compact single file.

Step-by-step instructions

• Configure your PDF settings — choose page size (A4 or Auto), margins, fit mode, and output quality.
• Add all the images you want using the upload area. Multiple images can be added at once.
• Drag the preview thumbnails to reorder the page sequence exactly as you want it.
• Click 'Create PDF' and your browser generates the file locally.
• The finished PDF downloads automatically to your Downloads folder.

How it works & Privacy

We use the open-source pdf-lib library running entirely in your browser to generate binary PDF documents from your image data. Each image is rendered onto an HTML5 canvas at high resolution, then embedded into the PDF structure using JPEG encoding. Everything stays within your device's memory — no server processing occurs.

Common Mistakes to Avoid

• Uploading images in the wrong order without reordering them — the PDF pages will reflect the exact upload order unless you drag them to the right sequence.
• Using very high quality for PDFs with 30+ images — this can create extremely large files that are slow to email or upload. Use 'Balanced' for multi-page documents.
• Forgetting that transparent PNG areas become white in the PDF — JPG embedding is used internally, which does not support transparency.
• Not checking the fit mode for official documents — 'Fill' mode crops the image to fill the page, which can cut off edges of important documents. Always use 'Fit' for official paperwork.
