Unfold every page of a PDF into a JPG image. It is drawn inside your browser, so contracts and ID scans never leave your device.
The PDF is opened by pdf.js, the open-source PDF renderer from Mozilla, which your browser downloads from a public CDN the first time you add a PDF. Each page is drawn onto a canvas at twice its nominal size — roughly 144 dpi — on a white background, the way it would look on paper, and then saved as a JPG at the quality you choose. The character maps needed for Chinese, Japanese and Korean documents are loaded as well, so text in those languages renders properly. The document itself is read from your disk into the page and never sent anywhere.
Up to 100 pages are unfolded per PDF; for longer documents, the list notes that only the first 100 were used. Very large pages, such as posters or engineering drawings, are scaled down so a single page stays under about 25 megapixels. Each page becomes its own image, named after the PDF with the page number — report-1, report-2 and so on, plus _conv and the .jpg extension — and the whole set can be saved as one ZIP. PDFs that need a password to open cannot be read.
JPG suits pages that are mostly photographs or scanned paper: the files stay small and look natural, which is what you want for sharing pages in a chat or attaching them to a form that only accepts images. For crisp text it is not ideal — JPG compression can leave faint smudges around letters and thin lines, especially at the Smaller setting. For text-heavy pages, choose High (94) or use PDF to PNG instead.
Everything runs inside your browser. Because the image never reaches a server, we cannot store it or look at it. That difference matters when the file is company material or a personal photo.
