PDF to Image — Convert PDF Pages to JPG, PNG, WebP (Free, In-Browser)
Render every PDF page as a high-quality JPG, PNG, or WebP image. Choose DPI (72-600). Outputs a ZIP. No upload, no watermark.
About PDF to Image
A PDF-to-image converter renders each page of a PDF as a standalone raster image (JPG, PNG, or WebP), preserving exact visual layout including fonts, images, and vector graphics. The ZTools PDF to Image tool uses `pdf.js` (the same engine Firefox uses) to render at any DPI from 72 (web) to 600 (print-quality), encodes via the Canvas API, and bundles the output as a ZIP for download. Useful for creating thumbnails, sharing PDF previews on platforms that don't render PDFs inline, or extracting figure-by-figure for slide decks.
Use cases
- Generating thumbnails for a PDF library or download page. Most websites need a preview thumbnail of each PDF in a downloads listing. Render the first page at 150 DPI, save as JPG, and drop into your `/thumbnails/` folder. Page 1 covers most preview needs.
- Sharing a PDF preview on social media or chat apps. WhatsApp, Slack, and Twitter render images inline but treat PDFs as attachments. Convert your PDF to a single tall PNG (one image per page concatenated) for an instantly visible preview that doesn't require a download.
- Embedding a PDF excerpt in a blog post or documentation. Render the relevant pages as PNG and embed via `<img>` — avoids the extra page-load cost of a PDF.js viewer and works in every browser, every email client, every CMS.
- Extracting individual figures or charts from a research paper. Render every page at 300 DPI, then crop the figures you need in our Image Cropper. Faster than copy-pasting from the PDF (which loses quality) or screenshotting (which is timezone- and OS-dependent).
How it works
- Drag-drop your PDF. File loads into browser memory; nothing leaves your device.
- Choose output format and DPI. JPG (smallest, lossy), PNG (lossless, best for text/graphics), WebP (smallest at quality). DPI: 72 (web small), 96 (web standard), 150 (good print), 300 (high-quality print), 600 (archival).
- Optionally select page range. Convert all pages, only the first N, or a custom list (e.g. "1, 3-5, 8"). Useful when you only need a cover image or a single figure.
- Click Convert. `pdf.js` renders each page to a canvas at the chosen DPI; the canvas is encoded to your chosen format and added to a ZIP via JSZip.
- Download the ZIP. Single output: direct image download. Multi-page output: ZIP with sequentially-numbered files (`page-1.png`, `page-2.png`, …).
Examples
Input: 20-page report at 300 DPI, PNG output
Output: ZIP with 20 PNG files (`report-page-1.png` … `report-page-20.png`), each ~600 KB
Input: Single-page contract at 150 DPI, JPG output
Output: One JPG (~120 KB), suitable for thumbnail or social-share preview
Frequently asked questions
What DPI should I choose?
For web display: 96 DPI is standard, 150 if you'll show large. For print: 300 DPI minimum, 600 for archival quality. Higher DPI means larger files and slower rendering — pick the lowest that meets your need.
Is text rendered crisply or as a blurry image?
Crisply, because `pdf.js` renders text as actual font glyphs at the requested DPI — not by capturing a screenshot of an existing render. At 300 DPI, text is print-publication quality.
Will my PDF be uploaded?
No. Rendering happens in your browser. Open DevTools → Network and verify there are no requests during conversion.
Can I extract just one page?
Yes — use the page-range field to specify a single page (e.g. "5") or a list ("1, 3, 7").
Why is my output huge?
High DPI + PNG output produces large files. Switch to JPG @ 85% quality for ~10× smaller files with little visible loss for photographic content.
Are vector elements (charts, line drawings) preserved as crisp lines?
They're rasterized at the chosen DPI — crisp at 300+ DPI, slightly soft at 96 DPI. For vector preservation, export to SVG via dedicated PDF-to-SVG tooling instead.
Pro tips
- For thumbnails: 150 DPI JPG is the sweet spot — small file, sharp preview.
- For print-publication figures: 300 DPI PNG.
- For social-media previews: render the cover page as JPG and post directly.
- Pair with our Image Compressor if file size is critical after rendering.
