Overview

Convert images into a single PDF document

Combining JPG, PNG, or other images into a PDF is one of the most frequent document tasks. PDFs are universally readable, easy to share, hard to accidentally edit, and accepted by almost every online portal that asks for "supporting documents". Converting a stack of photos to a single PDF is also a fast way to compile handwritten notes, business cards, receipts, contracts, and ID scans.

ToolHub Image to PDF lets you drop images, drag them into the correct order, choose a page size, and download a clean PDF. Every step happens in your browser, so the source images and the final PDF stay on your device.

Step-by-step

How to convert images to PDF

  1. 1

    Add your images

    Drop JPG or PNG files into the upload area. Add as many as you need. Each image becomes one page in the final PDF.
  2. 2

    Reorder pages

    Use the up and down arrows next to each image to set the page order. Number badges show the position so you can see at a glance where each image will appear.
  3. 3

    Pick a page size

    Fit to image keeps the original image dimensions for each page. A4 produces standard 210 by 297 mm pages with a small margin. Letter produces 8.5 by 11 inch pages, common in the United States.
  4. 4

    Build and download

    Click create PDF. The file is generated locally and downloads automatically.

Reference

Choosing a page size

The page size you pick affects how each image is laid out in the PDF.

Fit to image

Each page takes the exact dimensions of the image. There are no margins. Best when the original images already have the aspect ratio you want, like photo books or scanned manuscripts where you do not want any white space.

A4

The international standard at 210 by 297 mm. Used virtually everywhere outside the United States. Best for documents that will be printed on standard office paper. Images are scaled to fit with a small margin.

Letter

The US standard at 8.5 by 11 inches. Slightly wider and shorter than A4. Use this if the PDF will be printed in the United States, Canada, Mexico, or the Philippines.

Use cases

When to convert images to PDF

Submitting documents to a portal

Job applications, government forms, and university applications usually require PDF, not raw images.

Scanning notes or whiteboards

Snap photos of handwritten notes from class or a meeting and combine into a searchable archive.

Photo books and portfolios

Combine selected photos into a single PDF for sharing with clients or family.

Sending receipts for reimbursement

Roll up phone photos of receipts into one PDF that finance can attach to your expense report.

Sharing screenshots of a workflow

Compile screenshots into a PDF tutorial or bug report easier to email or print than separate files.

Archiving ID and business cards

Photo each side of an ID or card, then combine into one PDF for safe digital storage.

Tips for the best PDF results

  • Crop and rotate images before uploading. The PDF builder respects whatever orientation you give it.
  • Use Fit to image for photo galleries where you want zero white space.
  • Use A4 or Letter for documents you might print or that need standard page dimensions.
  • If your photos are very large (over 4000 pixels wide), consider compressing them first to keep the PDF size manageable.
  • Use a consistent aspect ratio across all images for the cleanest looking PDF.

Common questions

How many images can I add?

There is no enforced limit. Practical limits depend on your device memory. Hundreds of images may slow down older devices since everything is processed locally.

Why is my PDF so large?

PDF includes the images at their original resolution by default. High resolution photos produce big PDFs. Compress your images first using the image compressor for a much smaller PDF.

Can I add a cover page or title?

Not directly. You can create the title page as an image first using any text editor or screenshot tool, then place it as the first item in the order.

Will the images be searchable as text?

No. Images are embedded as pictures, not as text. To make a PDF searchable, you need optical character recognition (OCR) which is a different category of tool.
