How can I verify the PDF isn't uploaded?

Open your browser's DevTools (F12) and go to the Network tab, then use the tool. The only requests you will see are this site's own PDF.js script files (the library and its worker), which load when the tool first needs them, and blob: entries for the page images, which your browser holds in memory. None of them sends your file to our servers. All rendering happens locally in your browser tab using PDF.js.

Why convert a PDF to images without uploading?

Some files are not appropriate to send to a third-party service, and some networks block uploads altogether. Converting locally avoids both problems.

What are the image files called?

Each image keeps the PDF's name and adds the page number, so report.pdf gives report-page-1.jpg, report-page-2.jpg, and so on, or .png files when you pick PNG.

What resolution will the output images be?

Each PDF point becomes 1, 1.5, or 2 pixels, which is 72, 108, or 144 pixels per inch. At the default 1.5× an A4 page comes out at about 890 × 1,260 pixels, and 2× gives about 1,190 × 1,680. For print at 300 pixels per inch, even 2× is on the low side.

PDF to Image Without Uploading

Convert every page of a PDF to a JPEG or PNG image entirely in your browser. All processing runs in your browser, with no third-party service involved. Drop your PDF, choose a format and quality, and download the images.

How it works

Dropping a PDF lets the File API read its bytes into memory without uploading them. pdfjs-dist then parses those bytes and draws every page onto a Canvas, and canvas.toBlob turns each canvas into a PNG or JPEG that you download through a short-lived blob: URL, never a data: URL. The renderer and the encoder both live in your browser. Our servers are not involved at any point.

Processing runs in your browser

All rendering happens inside your browser tab. PDF.js processes your file entirely in memory; our servers are not involved at any point.
