Convert PDF to JPG — without uploading it
Pulling images out of a PDF for a slide, sharing a single page as a thumbnail, archiving scans as JPGs — lots of reasons to convert. Here's the browser-native version built on Mozilla's PDF.js.
- Mozilla PDF.js renders in your tab
- JPG / PNG output up to 192 DPI
- CJK + Arabic scripts supported
- Pick specific pages to convert
Render in the browser. Save as JPG or PNG.
PDF.js draws each page on a canvas, then exports it as JPG or PNG. The PDF and images never touch a server.
Open the PDF to Image tab
Click above or go to /pdf-to-image.
Drop your PDF
Low-res thumbnails render first so you can pick pages. 50 pages preview in ~3 seconds.
Pick format and quality
JPG for smaller files, PNG for sharper text. Scale: Low (1×), Medium (1.5×), High (2×).
Choose pages
'All' converts every page. 'Pick' lets you click specific thumbnails.
Hit Convert & Download
Each page renders, encodes, and bundles into a ZIP. 20 pages at Medium takes ~4 seconds.
Two formats. Three quality presets.
Practical notes.
JPG output
No alpha, smaller files. Best for photos and scans.
PNG output
Alpha supported. Best for screenshots and diagrams. 2–4× larger than JPG.
Quality scales
Low ≈ 96 DPI, Medium ≈ 144 DPI, High ≈ 192 DPI (roughly print quality).
Complex scripts
PDF.js loads CMap fonts for Chinese, Japanese, Korean, Arabic. Same render as your viewer.
Same logic. Your files stay yours.
The PDF you're converting often contains something private — an ID scan, a contract, a payslip. Online converters all upload and store renders on disk. You don't need that risk for a 1-second canvas render.
- ConvertIO and SmallPDF upload, render server-side, send back a ZIP
- Free tier limits 10 MB input and 25 conversions per day
- CJK fonts often render as tofu when servers lack CMap data
- PDF.js draws each page on a canvas in your tab
- You pick the scale: 1× (web), 1.5× (default), 2× (print)
- PDF.js auto-fetches CMaps for CJK and Arabic
This tool is intentionally simple.
Where browser-side conversion is wrong.
Want vector output (SVG)
Rasterises. For vector, use Inkscape or pdf2svg.
Want OCR text from a scan
Gives you a JPG of the scan, not the text. Run through Tesseract or Adobe OCR.
Need TIFF / BMP / WebP
JPG and PNG only. Convert with ImageMagick if needed.
Very large PDFs (500+ pages)
Pages render sequentially. A server with parallelism is faster for huge documents.
Things people ask about PDF→JPG conversion.
Will the JPGs lose quality vs the PDF?
Vector content gets rasterised, which is lossy regardless of format. Medium (1.5×) looks fine for most uses. Use High (2×) for print.
JPG vs PNG — which?
JPG for photos and scans. PNG for screenshots, diagrams, or anything needing transparency. PNG is 2–4× larger.
Can I get just one page as an image?
Yes. Switch to 'Pick' mode and click the one page. Download is a single image, no ZIP.
My PDF is 200 pages. Will it work?
Yes — expect ~30 seconds at Medium. Use 'Pick' if you only need specific pages. Over 500 pages may hit memory limits on phones.
