使用步驟

Upload PDF: Drag any PDF in — single page or 100+ pages. We extract each page as a raster image in your browser via pdfjs-dist.
Set JPG Options: Pick DPI: 72 (screen size, smallest file), 150 (standard print preview), or 300 (high quality, larger files). Set JPG quality (60-100%; 85 is balanced). Choose output naming: page-1.jpg, page-2.jpg, etc.
Convert: Click 'Convert to JPG'. Each PDF page is rasterized to a JPG image in your browser. A 20-page PDF at 150 DPI completes in 15-30 seconds.
Download ZIP: Get a single ZIP with all the JPGs, named sequentially. Extract and use anywhere — social media uploads, image galleries, slide inserts, or further processing.

常見問題

How do I convert a PDF to JPG images?

Drop your PDF into our PDF to Image tool, select 'JPG' as the output format, pick DPI and quality, click 'Convert'. You get a ZIP of JPG files — one per page. Runs in your browser, no upload, no watermarks.

What DPI should I choose?

For screen viewing and social media: 72 DPI is enough and produces small files. For standard previews and printing on home printers: 150 DPI is good. For high-quality print (300 DPI for a printer's expected DPI, e.g. photo book printing): use 300 DPI. Higher DPI = larger file size but sharper output.

Can I convert a 100-page PDF to JPG?

Yes — tested with 200+ page documents. Processing time scales with page count × DPI. A 100-page PDF at 150 DPI typically completes in 30-60 seconds on a modern device. The output ZIP will contain page-001.jpg through page-100.jpg.

Will my PDF be uploaded?

No. pdfjs-dist processes everything in your browser. Confidential reports, exam papers, personal documents — all stay on your device. Output JPGs and ZIP are created locally.

Can I get PNG instead of JPG?

Yes — for lossless quality, choose 'PNG' as the output format. PNG produces larger files but preserves every detail. JPG is recommended for photos and screen-size previews; PNG is better for screenshots and graphics with sharp edges or transparency.

What if I want only specific pages?

Use our PDF Split tool first to extract just the pages you need (e.g. pages 5-12), then run them through PDF to Image. Or use PDF Organize to delete unwanted pages, then convert. Both are local-only flows.
