How It Works

How the PDF to JPG Converter Works

DocDox PDF to JPG converter transforms each page of a PDF document into a high-quality JPEG image using PDF.js for rendering and the HTML Canvas API for export — entirely within your browser. Scanned documents, reports, and presentations are all handled correctly, including PDFs with embedded fonts and complex layouts.

Control the output resolution with a DPI slider. Higher DPI values produce larger, crisper images suitable for print or detailed review; lower values produce smaller files optimized for web sharing or email. Each page becomes a separate JPG file, and multi-page PDFs are packaged into a downloadable ZIP archive.

Because PDF.js renders pages directly to canvas on your device, even confidential or sensitive PDFs can be converted safely. No files are transmitted to any server, no watermarks are applied to output images, and there are no server-imposed file size restrictions.

Common Use Cases
→Convert presentation PDFs into shareable image slides for social media
→Extract diagrams or charts from reports as standalone image files
→Convert scanned document pages to images for processing in other apps
→Create image thumbnails of PDF pages for a document management system
Frequently Asked Questions

What resolution should I choose?

150 DPI is good for screen viewing, 300 DPI for print-quality output, and 72 DPI for small web thumbnails.

Do I get one file per page or a single ZIP?

Single-page PDFs produce one JPG. Multi-page PDFs produce a ZIP archive with one JPG per page.

Can I convert a password-protected PDF?

No. Remove the password protection first before converting.
