Why Convert Images to PDF?

PDFs are the universal document format — accepted everywhere from email attachments to government portals and business systems. Converting images to PDF ensures that your content is preserved exactly as intended, regardless of the device or operating system used to open it. Unlike image files, PDFs are harder to accidentally edit and easier to print professionally.

Scanned documents, photographs of receipts, hand-written notes, ID cards, and design mockups all benefit from being packaged as PDF. You can combine multiple images into a single, easy-to-share file — ideal for invoice batches, portfolios, or multi-page form submissions.

How Image-to-PDF Conversion Works

This tool uses pdf-lib — a pure JavaScript PDF library — running entirely in your browser. No files are ever uploaded to a server. Here is what happens under the hood:

1. Each image is read into memory. WebP images are first converted to JPEG via a canvas element.
2. The image is embedded into a new PDF page sized exactly to its pixel dimensions.
3. All pages are assembled in your chosen order and saved as a PDF file.
4. The resulting PDF is offered as a download — no watermarks, no size caps, no sign-up.
