PDF to JPG Converter

This tool turns the pages of a PDF into JPG images, one image per page, entirely inside your browser. It is for anyone who needs a page as a picture — to post a flyer on social media, put a slide into a chat, attach a scanned form to a site that only accepts images, or preview a document on a device without a PDF reader.

It works by drawing each page the way a PDF viewer does, then saving the drawing as a photo-style image. The drawing is done by pdf.js, the open-source PDF renderer maintained by Mozilla and built into Firefox. pdf.js paints the page onto an invisible canvas at the resolution you choose, the page is laid on white first (JPG has no transparency), and your browser's JPG encoder compresses the result at the quality you set — 90 out of 100 by default.

Resolution is set in DPI, dots per inch. A PDF measures pages in units of 1/72 inch, so the image size is simply the page size × DPI ÷ 72. A US Letter page (8.5 × 11 in, 612 × 792 units) comes out at 612 × 792 pixels at 72 DPI, 1275 × 1650 at 150 DPI and 2550 × 3300 at 300 DPI; an A4 page is 1240 × 1753 at 150 DPI. Use 72 DPI for a quick on-screen preview, 150 DPI for sharing and reading (the default), and 300 DPI when the image will be printed or you need to zoom into small text. The tool shows the exact pixel size of page 1 before you convert.

Know what you are giving up. A PDF page is made of text, fonts and vector shapes that stay sharp at any zoom; a JPG is a fixed grid of pixels. After conversion the text is part of the picture — you cannot select, search or copy it. Anything visible on the page, including filled-in form fields and annotation marks, is flattened into the picture; links stop working, and bookmarks, attachments and hidden comment text are not carried over. JPG compression is also lossy, which can leave faint smudges around sharp black text. If you want crisp text with no compression artefacts, use PDF to PNG instead; if you need the text back as text, the original PDF is the better file to keep.

To keep the browser tab from running out of memory, one conversion is limited to 200 pages and 1,000 megapixels in total, and a single page cannot exceed 100 megapixels or 16,384 pixels per side — about a 54-inch page at 300 DPI. When a request goes over, the tool tells you which page and which lower resolution will work. Password-protected PDFs have to be unlocked first: open the file with its password in a PDF reader, save an unprotected copy, and convert that.

The PDF never leaves your device. pdf.js runs from this site's own server, the file is read into your browser's memory, and the images are created there. You can check in your browser's developer tools, under the Network tab, that no request carries your file.

1. The file's first bytes are checked for the %PDF- header, so a JPG or Word file renamed to .pdf is named for what it is. Files over 200 MB are refused before they are read into memory. 2. pdf.js opens the PDF and reports the page count and the size of each page in PDF units (1/72 inch), with any page rotation applied. 3. The pages you chose (All, or a range like 1-3, 5) are checked: at most 200 per conversion. 4. Each page's pixel size is computed as width × DPI ÷ 72 and height × DPI ÷ 72, rounded down. A page over 100 megapixels or 16,384 px per side, or a total over 1,000 megapixels, is refused before anything is drawn, with the resolution that would fit. 5. Pages are rendered one at a time: a canvas of that size is painted white, pdf.js draws the page onto it, and canvas.toBlob("image/jpeg", quality) encodes it. The canvas is then released before the next page. 6. Files are named after the PDF with a zero-padded page number — report.pdf becomes report-page-01.jpg, report-page-02.jpg … — so they sort in page order. Download each one, or all of them as a ZIP built in the browser.
