PDF · up to 100 MB per file
Export every page as an image. DPI is the setting that matters: 96 for on-screen preview (A4 is about 794×1123), 150 as the default (sharp with a manageable size) and 300 for print (2480×3508, several megabytes per page) — remember that doubling the DPI quadruples the pixels, so a 40-page document at 300 DPI occupies hundreds of megabytes, which is why there is a per-page pixel limit with a clear message. Rendering uses pdf.js, the same engine as the Firefox reader, so embedded fonts, vector art and transparency all come out right — and a page's own rotation flag is honoured, which means scans export upright. File names are zero-padded (`-p01`, `-p02`) so sorting by name is sorting by page.
Features
- One image per page, PNG or JPEG
- Three DPI steps: 96 (screen), 150 (default), 300 (print)
- A page's own rotation flag is applied, so scans come out upright
- Zero-padded names: name order is page order (p10 never sorts before p2)
- Export selected pages only (ranges such as 1-3,5)
- Progress shown, so a long document tells you which page it is on
- A page past the pixel limit reports an error and suggests a lower DPI instead of freezing the tab
- Nothing is uploaded and no server is involved
How to use
- Drop a PDF in
- Choose the DPI and image format
- Give a page range if you only need some pages
- Download images one by one, or use Download all
FAQ
- Why are the images larger than the PDF?
- Because text and vector art in a PDF are instructions ("draw a line here") while an image is pixels ("these two million dots are these colours"). A page of plain text may be 20 KB inside the PDF and 1–3 MB as a 300 DPI PNG. To shrink it: drop to 150 DPI (a quarter of the pixels) or switch to JPEG (less than half the size for photo pages). Conversely, if the PDF is a scan to begin with, the images may come out smaller — PNG does not necessarily compress scans worse than PDF does.
- The text in the exported image looks grey and blurry.
- Almost always too low a DPI: fine on screen, mushy when zoomed or printed. Try 300 DPI. The other case is that the image inside the PDF was low resolution to begin with (some scans are stored at 72 DPI), in which case a higher DPI only enlarges the blur — the tool will not invent detail that is not there.
- Can the export be searchable text?
- No — an image carries no text layer, which is what rasterising means. If you want "turn a PDF into editable text", that needs OCR, a different kind of tool. If what you want is precisely the uncopyable image (to stop someone extracting the text), rasterising is the way, and 300 DPI keeps it sharp.
- Is the file uploaded?
- No. Rendering happens in the browser through pdf.js (inside a Web Worker, so the page stays responsive) with no network requests at all, and it works offline.
