Images to PDF & PDF to Images Converter
Convert JPG, PNG, WebP, and AVIF images into a formatted multi-page PDF document, or render PDF pages into high-resolution PNG, JPEG, WebP, or AVIF images in your browser.
Method and assumptions
In Images → PDF mode, each input image is decoded honoring EXIF orientation, normalized to JPEG or lossless PNG, and embedded into a new pdf-lib document using either exact image dimensions or scaled proportionally inside A4 or US Letter pages with configurable margins. In PDF → Images mode, pdfjs-dist renders each page vector tree onto a high-DPI HTML5 canvas (1x 72 DPI, 2x 144 DPI, or 3x 216 DPI) and encodes PNG, JPEG, WebP, or AVIF outputs.
Common mistakes and edge cases
Rendering very long PDF documents at 3x (216 DPI) consumes significant canvas memory on mobile browsers; use 1x or 2x scale for large page counts.
How to use
- Choose Images → PDF to combine images into an A4, US Letter, or fit-to-image PDF with configurable margins.
- Or switch to PDF → Images and drop a PDF to render every page at 1x (72 DPI), 2x (144 DPI), or 3x (216 DPI).
- Download individual converted files or export all rendered pages as a single ZIP archive.
Example
Drop two presentation slides in Images → PDF mode with A4 Landscape and 24 pt margin to generate a 2-page PDF, or switch to PDF → Images on a 3-page brief at 2x scale to download three crisp 144-DPI PNG images in a ZIP.
Frequently asked questions
- Does Images → PDF preserve image orientation?
- Yes. Embedded EXIF orientation flags are honored before embedding into the PDF pages.
- Which resolution scale should I choose for PDF → Images?
- 2x (144 DPI) provides crisp text and graphics for presentations and web sharing; 3x (216 DPI) is best for print-ready extraction.
