Convert PDF to JPG Images Online for Free

DPI guide by use case:

• ·72 DPI — Screen previews, web thumbnails, internal sharing. Small files. Not printable.
• ·96 DPI — Slightly larger screen-quality images. Good for embedding in Word documents or presentations.
• ·150 DPI — Website publication, digital reports, email attachments. Good quality on screen; borderline for laser printing.
• ·300 DPI — Professional print quality. Suitable for most commercial printing needs. The standard for print-ready deliverables.
• ·600 DPI — Engineering drawings, fine print, document archiving. Very large files. Only necessary for complex technical content.

JPG quality setting:

• ·85-90% — Recommended for most uses. Imperceptible quality loss from lossless, much smaller file.
• ·70-80% — Smaller files, slight visible artifacts at full zoom. Fine for web and email.
• ·95%+ — Near-lossless. Larger files. Only needed for print or further editing.

Single page vs all pages: Convert one page for preview or testing your DPI setting, then run all pages once you are satisfied with the output.

JPG vs PNG output from PDF: JPG is lossy and smaller; PNG is lossless and larger. For photos and complex page backgrounds, JPG gives excellent quality at much smaller files. For pages with text, line art, or transparency that you want to preserve exactly, use PDF to PNG.

PDF to JPG vs screenshot: Taking a screenshot of a PDF page captures whatever your screen renders at screen resolution (typically 72-96 DPI). A proper PDF-to-JPG conversion renders at the DPI you specify, giving much higher quality for the same page content.

When to convert PDF to image: Convert to image when you need the PDF content in an image format — for embedding in a non-PDF presentation, sharing as a social media image, or using in a design application. Keep the original PDF for document purposes.

Converting a PDF to JPG exports each page as a raster image file. The key variable that most tools hide or default poorly is DPI (dots per inch) — the rendering resolution. DPI determines whether your JPG output is sharp enough for its intended use.

At 72 DPI, a standard A4 page exports as roughly 595×842 pixels. This is sufficient for screen display but too low for printing. At 150 DPI, the same page becomes 1240×1754 pixels — good for web publishing and presentations. At 300 DPI, the page becomes 2480×3508 pixels — suitable for print and detailed inspection. Some use cases need even higher.

Choosing the wrong DPI is the most common mistake: people export at 72 DPI intending to print the result and wonder why it looks blurry, or export at 300 DPI intending to use it as a web thumbnail and create unnecessarily large files. This tool makes DPI explicit and shows the resulting pixel dimensions before you export.
