How to use the Image to PDF Converter? – Step-by-Step

You can easily convert your images to PDF by following the steps below.

Step 1: Upload Images

First, select the image(s) you wish to convert to PDF. You have three convenient methods to upload images:

• Drag & Drop: Drag the images from your device and drop them into the designated upload area. You can upload multiple images at once.
• Browse Button: Click the ‘Browse’ button to select images from your device.
• Link Button: If you have an online link to an image, click the ‘Link’ button to add the image directly using its URL.

Step 2: Review Uploaded Images

After uploading, you will see options beneath each image –

• Rotate Button: If an image is upside down or sideways, click the ‘Rotate’ button to adjust it to the correct orientation.
• Delete Button: If you accidentally upload an image, click the ‘Delete’ button to remove it.

This allows you to arrange all the images according to your preference before generating the PDF.

Step 3: Select Page Size

Next, select the page size for the PDF –

• A4: This is the most popular size for documents, reports, printing, and official work.
• Letter: This size is commonly used for international or business documents.
• Auto Fit: The page automatically adjusts to fit the size of each image, ensuring the image quality and aspect ratio are well-preserved.

Step 4: Select Page Orientation

Choose the orientation for the PDF pages –

• Portrait: Use this option to set the page vertically. It is suitable for standard documents.
• Landscape: Use this option to set the page horizontally. It is ideal for presentations.

Step 5: Select Margin

Use the Margin option to determine the amount of empty space around the page –

• No Margin: No extra margin; the image will cover the entire page.
• Small (10mm): Adds a small 10mm margin around the image.
• Medium (20mm): Adds a 20mm margin around the image, providing a cleaner look.
• Large (30mm): Adds a 30mm margin around the image. Use this if a larger margin is required for printing or official documents.

Step 6: Select the PDF creation mode

You will see two options here –

• Merge All Images into One PDF: All images will be combined into a single PDF file. Example: 10 images → 1 PDF. This is the most commonly used option.
• Separate PDF for Each Image: A separate PDF will be created for each image. Example: 10 images → 10 PDFs. You can use this option when you need individual PDF files.

Step 7: Click the “Convert to PDF” button

Once you have configured the settings, click the “Convert to PDF” button. Your PDF file will be generated in just a few moments.

Step 8: Download or Share the PDF

What technology powers an Image to PDF Converter?

1. HTML5 File API: This is used to select images from the gallery or file manager. It allows the browser to read the files selected by the user.

2. JavaScript: This controls the entire conversion process. Loading, rotating, and deleting images, as well as generating the PDF, are all handled by JavaScript.

3. Canvas API: Images are rendered onto a canvas. Operations like rotating, resizing, cropping, and other image processing tasks are typically performed using the Canvas API.

4. PDF Generation Library: The PDF is created using canvas or image data. Popular libraries include:

• jsPDF
• pdf-lib
• PDFKit

jsPDF and pdf-lib are the most commonly used libraries in web applications.

5. Browser Memory: Uploaded images are temporarily stored in the browser’s memory. They are cleared once the PDF generation is complete.

6. Blob & File Download API: The generated PDF is initially created as a Blob (Binary Large Object). Then, the browser’s download API is used to save the file to the user’s device.

Simply put:

Gallery → HTML5 File API → Canvas API → JavaScript Processing → jsPDF/pdf-lib → Blob → Download

This entire process takes place within the browser itself. Therefore, it is referred to as Client-Side PDF Conversion or Browser-Based PDF Conversion. The core technologies behind PDF generation are JavaScript, the Canvas API, and a PDF library (such as jsPDF or pdf-lib).
