Render any PDF's pages as JPG or PNG images — pick the DPI, batch-export as ZIP
Quick answer: to convert PDF to JPG, load the file above, choose a resolution and JPEG or PNG, and press Convert. Each page renders at exactly your chosen DPI — an A4 page is 595×842 px at 72 DPI, 1240×1754 at 150, and 2480×3508 at 300 — then downloads as one image or a single ZIP for multi-page files. Nothing uploads.
| DPI | A4 page (595.28×841.89 pt) | Letter page (612×792 pt) | Best for |
|---|---|---|---|
| 72 | 595 × 842 px | 612 × 792 px | Thumbnails, quick previews |
| 96 | 794 × 1123 px | 816 × 1056 px | Screens, email, chat |
| 150 | 1240 × 1754 px | 1275 × 1650 px | Everyday viewing and sharing |
| 200 | 1654 × 2339 px | 1700 × 2200 px | Crisp reading of small type |
| 300 | 2480 × 3508 px | 2550 × 3300 px | Printing, zooming, archiving |
A PDF point is 1/72 inch, so render scale = DPI ÷ 72. Pixel counts are the page size in points multiplied by that scale and rounded — 595.28 × (150 ÷ 72) = 1240.2 → 1240 px wide.
Two engines do the work in your browser: pdf.js (the renderer behind Firefox's PDF viewer) draws each page onto a canvas at exactly the pixel density you asked for, and the page's canvas encoder turns that drawing into a real JPEG or PNG file. Multi-page exports get bundled with JSZip so you receive one download instead of thirty.
The renderer scales the page by DPI ÷ 72, because PDF units are points (1/72 inch). An A4 page at 150 DPI scales by 2.083, from 595.28 × 841.89 points to 1240.2 × 1753.9 pixels, rounded to a 1240 × 1754 canvas. Double the DPI and both dimensions double — which quadruples pixel count, since 2480 × 3508 is four times the pixels of 1240 × 1754. That's why 300 DPI files are roughly four times heavier, not two.
Load the PDF, and the tool reports its page count and page size. Pick DPI and format; if you chose JPEG, the quality slider (default 85) trades size against fidelity. Restrict the export with a range like 1-3,7 or leave it empty for everything. Convert, and the table lists each page's pixel dimensions and actual byte size before the image or ZIP downloads.
A 5-page A4 contract at 150 DPI, JPEG at 85. Page 1 renders to a 1240 × 1754 canvas — 2.18 million pixels — and encodes in a few hundred milliseconds. A mostly-text page typically lands in the low hundreds of KB at this setting, a page with a scanned photo somewhere higher; the table shows the true number per page. All five pages zip into one file named pages-150dpi.zip containing page-1.jpg through page-5.jpg. Need one page for a slide deck? Set the range to that page number, and it downloads directly.
Load the PDF above, pick a resolution (150 DPI is the balanced default), choose JPEG or PNG, and press Convert. One page downloads directly; multiple pages arrive as a ZIP with one image per page, named page-1, page-2, and so on. The rendering happens in your browser, so contracts and IDs never upload to anyone's server.
Match the destination. 96 DPI is enough for screens, email, and chat (an A4 page becomes 794 by 1123 pixels). 150 DPI (1240 by 1754 on A4) suits documents you'll view closely or print casually. 300 DPI (2480 by 3508 on A4) is print-shop quality. Above 300 you're mostly inflating file size, because the source PDF's text and images only carry so much detail.
JPEG for pages with photos, scans, or gradients - it compresses that content to a fraction of PNG's size with no visible loss at quality 85 or higher. PNG for pages that are mostly flat graphics: screenshots, charts, logos, text on solid backgrounds. PNG keeps edges pixel-crisp and supports transparency; JPEG makes photos smaller.
Yes. The page range field takes a list like 1-3,7 — pages 1 through 3 and page 7. Leave it empty for the whole document. Anything out of range is ignored with a note rather than failing the whole export.
It rasterizes: the page's vector text and line art become pixels, so quality depends entirely on the DPI you choose. At 300 DPI the result is print-sharp for normal text; at 72 DPI small type goes soft. Photos inside the PDF keep roughly their native resolution as long as your chosen DPI doesn't shrink them. Text in the image is no longer selectable or searchable - that's the format change, not a flaw.
Pixel count quadruples from 150 to 300 DPI (an A4 page goes from 1240 by 1754 to 2480 by 3508 pixels, about 2.2 million to 8.7 million pixels), so files grow accordingly. If quality is 85 or lower and the page is photo-heavy, JPEG usually lands between a few hundred KB and a few MB per page. Drop to 150 DPI or use JPEG instead of PNG if size matters more than zoomability.
