PDF to JPG

How do I convert a PDF to JPG images?

1. Drop a PDF onto the drop zone, or click it to choose one or more files.
2. Under Resolution, choose 72 dpi (screen), 150 dpi (good) or 300 dpi (print).
3. Set JPG quality; 85% is a good balance between size and sharpness.
4. In Pages, type the pages you want, such as 1-3, 5, or leave it blank for every page.
5. Click Convert to JPG.
6. Download the single image, or click Download all as ZIP when there is more than one page.

PDF to JPG uses PDF.js, the same open-source renderer built into Firefox, to draw each page onto a canvas in your browser and then encode that canvas as a JPEG. Text, vector graphics and embedded images are all flattened into one picture per page, so the result looks exactly like the page on screen but can no longer be edited as text. Page 1 becomes the first JPG, page 2 the second and so on, with the page number in the file name.

Resolution decides how many pixels each page gets. At 72 dpi an A4 page is about 595 × 842 pixels, enough for a thumbnail or a quick preview. At 150 dpi it is about 1240 × 1754 pixels, which reads clearly on any screen and is the sensible default for sharing, slides and social posts. At 300 dpi it is roughly 2480 × 3508 pixels, matching what a printer needs for crisp text, at the cost of files several times larger. JPG quality controls compression: 85% is hard to tell from 100% but noticeably smaller, while values under 60% start to show blocky artefacts around text.

Use the Pages box to avoid converting a whole report when you only want the chart on page 7. Ranges follow the usual pattern, 1-3, 5, and page numbers start at 1. There is no limit on page count or file size beyond your device's memory, but a 300 dpi render of a 100-page document produces around 100 MB of images, so pick the lowest resolution that does the job. Several pages are bundled into a ZIP; a single page downloads as a plain JPG.

The conversion runs entirely on your device. The PDF is not uploaded, nothing is stored and there is no account or watermark. If you need transparent backgrounds or lossless output, JPG is the wrong format; convert to JPG here and then use an image tool, or keep the PDF and use PDF to Text if you only need the words.

How it works: this tool uses pdf-lib and PDF.js (Mozilla), open-source libraries loaded into your browser. No server is involved, so Kilnfile never sees your file. Last reviewed 20 September 2026.
