How It Works
Upload your PDF
Drop in any PDF. All pages are rendered as a preview so you can see the output quality before downloading.
Choose format and quality
Select JPG (smaller file), PNG (lossless, transparent), or WebP (best compression). Set DPI for resolution.
Download images or ZIP
Download individual page images or all pages as a single ZIP file.
Why SynthPDF?
3 output formats
JPG for general use, PNG for lossless and transparency support, WebP for web-optimised files with smallest size.
Adjustable DPI
Choose 72 DPI (web), 150 DPI (standard), or 300 DPI (print quality) — matching your target use case.
Download all pages as ZIP
Convert a 50-page PDF and download all 50 images in one ZIP file — named page-001.jpg through page-050.jpg.
Browser-only — no upload
Rendering runs client-side using PDF.js and Canvas API. Your files never leave your device.
Also converts Image to PDF
The same tool works in reverse — combine multiple JPG or PNG images into a single PDF document.
No watermarks. No account.
Converted images are clean — no overlaid watermarks or branding, even on the free plan.
When to Convert PDF to Images
- Social media posting — most platforms don't accept PDF; converting to JPG lets you share slides and document pages
- Presentations — insert PDF pages as images in PowerPoint or Google Slides
- Thumbnails and previews — create cover images from the first page of a PDF for website galleries
- Document review — share individual pages as images for clients who don't have PDF readers
- Web embedding — embed document pages as images on a webpage without JavaScript PDF viewers
JPG vs PNG vs WebP — Which to Choose?
- JPG — Best for most documents. Small file size with good quality. Slight quality loss (compression artefacts) on high contrast edges. Use for: general sharing, email, social media.
- PNG — Lossless — no quality degradation. Supports transparency. Larger files than JPG. Use for: screenshots, diagrams with sharp text, anything requiring perfect fidelity.
- WebP — Google's format. 25–35% smaller than JPG at the same quality. Supported by all modern browsers. Use for: web publishing, WordPress, web apps.
Understanding DPI for PDF Conversion
DPI (dots per inch) controls how many pixels represent each inch of the PDF page. A standard A4 page at 72 DPI is 595×842 pixels. At 300 DPI it's 2480×3508 pixels.
- 72–96 DPI — screen/web quality. Fast to load, small file size.
- 150 DPI — good balance. Suitable for email and digital viewing.
- 300 DPI — print quality. Use when printing the extracted images.
SynthPDF vs. iLovePDF for PDF to JPG
Both tools offer PDF to JPG conversion. The key difference: SynthPDF runs the conversion in your browser (no file upload), while iLovePDF uploads to their servers. For sensitive documents, SynthPDF's browser-based approach is the safer choice. For very large PDFs (100+ MB), both tools have their limits on free plans.
