Each PDF page is rendered as a JPG image at the selected DPI. Higher DPI = larger file size but better resolution (sharp for printing). Lower DPI = smaller file size, suitable for web or email.
How PDF-to-JPG Conversion Works
Each PDF page is rendered as a canvas element at the specified DPI:
1. PDF.js renders each page at the requested resolution (DPI × dimensions) 2. The canvas is captured as a JPG image using quality compression (85% default) 3. Each page's JPG is generated as a separate file 4. All JPGs are packaged into a downloadable ZIP archive
**DPI guide**: - 72 DPI: Standard screen resolution, smallest file size, suitable for email and web - 150 DPI: High-quality screen display, good for viewing on high-DPI monitors - 300 DPI: Print quality, suitable for printing on paper (crisp text and images) - Custom DPI: Enter any value; higher DPI = larger file, more detail
**File size estimate**: A typical page at 300 DPI is approximately 1.5-3 MB as a JPG, depending on image complexity. At 72 DPI, the same page is approximately 150-300 KB.
- Client-side rendering - no PDF upload
- Selective page conversion
- DPI selection controls quality vs. size
- Output as ZIP archive of individual JPGs
Worked Example
Example: Converting a 5-page PDF portfolio:
- At 72 DPI: Each page ≈ 200 KB, total ZIP ≈ 1 MB (fast email, web use) - At 150 DPI: Each page ≈ 600 KB, total ZIP ≈ 3 MB (high-quality screen, presentations) - At 300 DPI: Each page ≈ 2 MB, total ZIP ≈ 10 MB (print-ready, may be large for email)
The calculator shows estimated file sizes before conversion so you can choose the right resolution for your purpose.

Open calculator →Frequently Asked Questions
Will the JPG images look blurry at 72 DPI?
At 72 DPI, JPG images look fine on screen (computers, phones, tablets) but may appear soft if printed larger than 8.5×11 inches. For print, use 150-300 DPI.
Can I convert specific pages only?
Yes. The calculator lets you select which pages to convert (all, or specific page numbers like 1, 3, 5-8).
Are the JPG images lossy?
Yes. JPG is a lossy compression format. The calculator uses high-quality settings (85% quality) to minimize visible artifacts, but some quality loss is inevitable compared to the original PDF's vector graphics.
