How it works
This one really does rasterise, and here is what that costs
Every other PDF tool on this site copies page objects so the text layer survives. This one cannot: an image has no text layer by definition. pdf.js interprets each page's content stream and paints it onto a canvas at a viewport scale derived from the resolution you pick — PDF's user space is 72 units to the inch, so 150 DPI is a scale of about 2.08 and 300 DPI is roughly 4.17. What comes out is a faithful picture of the page and nothing more: no selectable text, no working links, no accessibility structure, and a file that will blur if someone zooms past the resolution you chose. That is fine when you need an image. It is the wrong tool for everything else.
- Resolution
- 72 DPI is scale 1 and matches PDF user space. 150 DPI suits screen use, 300 DPI is print quality and costs about four times the pixels.
- PNG or JPG
- PNG is lossless and right for text and line art. JPG is far smaller for scanned photographs and adds visible ringing around sharp glyph edges.
- Sequential rendering
- Pages are rendered one at a time with a capped scale on very large documents, so a long PDF does not get the tab killed on a phone.
- ZIP output
- Files are named after the source with a zero-padded page number and stored rather than deflated, since PNG and JPEG do not compress twice.
How to use it
How to convert a PDF to images online
- 01
Open the PDF
Parsed by pdf.js in the tab. Page count and size are read straight from the file.
- 02
Pick format and resolution
PNG or JPG, and the DPI that matches whether it is for screen or print.
- 03
Download the ZIP
Pages render in order with visible progress, then pack into one archive in the browser.
Where it earns its keep
Where an image beats a PDF
- Dropping a page of a report into a slide deck without an embedded-PDF placeholder.
- Posting a page where the reader will not open a PDF attachment.
- Producing thumbnails of a document for a catalogue or a listing page.
- Getting a page into an image editor to annotate it before sending it back.
Questions
PDF to Images, answered
Will the exported images have selectable text?
No. Rasterising converts the page to pixels, so text becomes shapes — unsearchable, unselectable and invisible to screen readers. If you need the text, keep the PDF or extract the pages instead of exporting images.
What resolution should I choose?
150 DPI for anything read on a screen, 300 DPI if it will be printed or zoomed. Going higher mostly buys you file size: 600 DPI is four times the pixels of 300 for detail that no ordinary display or printer resolves.
Is my PDF uploaded to be rendered?
No. pdf.js renders every page inside this browser tab and the ZIP is packed there too, so a confidential document is never handed to a rendering service — which is precisely what most online converters are.
Why is a long document slow?
Because your device is doing the rendering, page by page, deliberately. Rendering everything at once would spike memory and get the tab killed on mobile, so the trade is patience for reliability — and there is no upload wait at either end.
