Which resolution should I pick?

144 dpi is a good default: sharp on screen without producing enormous files. Use 72 dpi for a quick preview, and 288 dpi only when the image is going to be printed — a large page at that scale takes a moment to draw.

PNG for pages that are mostly text or diagrams, where its lossless compression keeps edges crisp. JPEG for pages that are mostly photographs, where the file will be several times smaller.

Will the text still be searchable?

No. Rendering turns a page into a grid of pixels, so the text becomes part of the picture. That is inherent to converting a document into an image, not a limitation of this tool.

Why are the pages saved one at a time?

Because a page that triggers a dozen downloads at once is a page browsers start blocking. Each preview has its own save button, so you download exactly the pages you want.

PDF to Images

Turn PDF pages into pictures. Choose which pages and at what resolution, see each rendered page as a preview, and save the ones you want. Everything is drawn in your browser using Mozilla's PDF renderer — the same engine Firefox uses — so the document never leaves your device.

Each page is drawn to a bitmap at the resolution you choose, so the text stops being text — the result is a picture of the page and cannot be searched or selected. Pages are saved one at a time rather than as an archive, because a browser that downloads a batch unprompted is a browser that starts blocking downloads.

Private by default

This tool runs entirely in your browser. Your data is never uploaded to a server.

How it works

How a page is drawn

pixel size = page size in points × scale · 72 dpi × scale = output dpi

Each page is laid out at its natural size in points and then drawn onto a canvas enlarged by the scale you chose. Because a point is 1/72 inch, a scale of 2 produces 144 dots per inch.

A white background is painted first: PDF pages have no background of their own, and without it the paper would be transparent and turn black in a JPEG.
Rendering uses pdf.js, the engine built into Firefox, so pages look the way a browser would show them.
The renderer runs in a Web Worker served from this site, not a CDN — nothing about the document is requested from a third party.
An A4 page at 288 dpi is about 2,384 × 3,370 pixels, which is roughly 8 megapixels per page.

For reference

Resolution against output size

For a single A4 page, 595 × 842 points.

Scale	Resolution	Pixels	Suitable for
1×	72 dpi	595 × 842	Quick preview, thumbnails
2×	144 dpi	1190 × 1684	Screen reading, most uses
3×	216 dpi	1786 × 2526	Large screens, light printing
4×	288 dpi	2381 × 3368	Printing — slow and heavy

Doubling the scale quadruples the pixel count and the memory needed, so a long document at 4× is worth rendering a few pages at a time.
