How to convert a PDF to JPG images

Sometimes you need a PDF's pages as plain images — to drop a page into a slide deck, post a document to social media, embed a figure on a web page, or attach a preview where a PDF wouldn't display inline. This tool renders every page of a PDF to a sharp image and gives you the whole set as a ZIP, all without uploading your file anywhere.

How the rendering works

Each page is drawn by pdf.js onto an off-screen canvas at the resolution you choose, then exported in your selected format. The DPI setting controls how many pixels each page contains: a higher DPI produces a larger, crisper image, while a lower DPI produces a smaller, lighter one. Because the rendering matches what a PDF viewer would show, the images look exactly like the original pages.

Picking the right format

The format decision comes down to what kind of marks are on the page, not the page itself:

• JPG — continuous-tone content like photos and colour scans, where its smaller size costs no visible quality.
• PNG — hard edges: body text, line art, screenshots, and anything destined for OCR, all of which stay razor-sharp because PNG is lossless.
• WebP — a good default when you are unsure, landing near PNG clarity at near JPG weight.

The quality slider only applies to JPG and WebP; PNG ignores it because it never throws pixels away. At 90% and above the loss is invisible on ordinary pages, so lower the slider only when you deliberately want smaller files.

Choosing a resolution

Pick the DPI from where the image is going: 150 for screens and the web, 300 for print, 72–100 for thumbnails. A concrete sense of scale: an A4 page at 150 DPI is about 1240 × 1754 pixels, while the same page at 300 DPI is roughly 2480 × 3508 — four times the pixels, four times the memory, and usually no extra detail unless the source itself was that fine.

Rendered locally, every page in the tab

Unlike merging or rotating, this tool actually re-draws each page from scratch — yet even that heavier rendering happens through pdf.js and the canvas API on your own hardware, with JSZip packing the results in-browser. No frame of a contract or a medical record is ever sent upstream; the conversion is as private as it is local.

Things to keep in mind

The conversion is a one-way trip for text. Every page comes out as a flat raster, so what used to be selectable, searchable characters is now just an arrangement of pixels — the reason to always keep the source PDF, or to run the exported images back through OCR if you need the words again later. This is the mirror image of the Images-to-PDF tool, which makes the same trade in the opposite direction.
