Converting PDF pages to images
There are many situations where you need a PDF as images rather than as a document: embedding a page in a presentation, posting a single page to social media, attaching a preview that opens without a PDF reader, or extracting a chart for reuse. Converting PDF pages to PNG or JPG solves all of these, and it can be done entirely in your browser.
PNG or JPG?
The choice mirrors the general format rules. PNG is lossless and ideal for pages that are mostly text, line drawings, tables, or diagrams, where crisp edges matter and you want no compression artefacts around the letters. JPG is better for pages dominated by photographs, where its compression produces much smaller files with no meaningful quality loss. If a page mixes both, PNG is the safer default; if file size is critical, try JPG and inspect the text closely.
Understanding scale
When a PDF page is rendered to an image, the scale factor controls the resolution of the output. A scale of 1.0 renders at the PDF's native size, which is often too low for crisp results on modern screens. A scale of 1.5 is a good general-purpose setting, balancing sharpness and file size. A scale of 2.0 produces high-resolution images suitable for printing or zooming, at the cost of larger files and more processing time. For text-heavy pages you intend to read on screen, 2.0 noticeably improves legibility.
How the in-browser conversion works
The tools on this site use PDF.js, an open-source PDF rendering engine that runs entirely in JavaScript. When you load a PDF, it is parsed and rendered to a canvas inside your browser, and the canvas is then exported as a PNG or JPG. Because all of this happens locally, your PDF is never uploaded to a server — important when the document contains contracts, financial records, or other sensitive material.
Practical tips
Very large or graphically complex PDFs require more memory and time, so be patient with long documents. If you only need a few pages, it is faster to extract just those. And because the conversion is local, you can safely process confidential documents that you would never want to upload to an unknown online service.
