How to convert PDF to JPG free
- Open the PDF to JPG tool.
- Upload your PDF.
- Choose your settings:
- Format: JPG (smaller file) or PNG (lossless, with transparency).
- DPI: 72 for web preview, 150 for general use, 300 for print-quality.
- Click Convert and wait for pages to render.
- For single-page PDFs, download one image directly. For multi-page PDFs, download a ZIP file containing all pages.
Understanding DPI
DPI (dots per inch) controls the image resolution:
- 72 DPI: Screen-quality, small files. Good for web thumbnails.
- 150 DPI: Good quality, moderate file size. The safe default.
- 300 DPI: Print quality, large files. Slow on mobile for large pages.
Tip: Avoid 300 DPI on mobile, rendering a large page at high resolution uses significant memory and may be slow or fail on older devices.
JPG vs PNG: which to choose?
| Format | Best for | File size |
|---|---|---|
| JPG | Photos, scanned pages | Smaller |
| PNG | Text, diagrams, transparency | Larger |
For most document conversions, JPG at 90% quality is the right choice.
Privacy: does anything leave my device?
No. This tool uses pdf.js (the same engine as Firefox's built-in PDF reader) running as WebAssembly in your browser. No file data is transmitted.
