Sometimes you need a PDF page as an image — to share a single page on social media, embed it in a presentation, use it as a thumbnail, or insert it into a document that doesn't support PDF files. PDFlexa converts each PDF page to a high-resolution JPG or PNG image, entirely in your browser.
JPG vs. PNG: Which Format Should You Choose?
| | JPG | PNG | |--|-----|-----| | Best for | Photos, scanned pages with colour gradients | Text-heavy pages, logos, diagrams with sharp edges | | File size | Smaller | Larger (but lossless) | | Transparency | Not supported | Supported | | Quality | Lossy compression (some quality loss) | Lossless (no quality loss) |
Rule of thumb: Use JPG for scanned documents and pages with lots of photos. Use PNG when you need crisp text, sharp lines, or a transparent background.
How to Convert PDF to JPG Online
Reduce your PDF file size instantly. No software needed.
- Open PDFlexa's PDF to JPG tool.
- Upload your PDF.
- Select which pages to convert: all pages, a single page, or a range.
- Choose the output format (JPG or PNG).
- Set the image quality/resolution (higher = sharper but larger file).
- Click Convert and download your images.
If the PDF has multiple pages, you'll receive a ZIP archive containing one image per page.
How to Convert PDF to PNG Online
The process is identical — just select PNG in step 4. Use PDFlexa's PDF to PNG tool if you want to start directly on the PNG output option.
Getting Sharp Images: Resolution (DPI) Explained
Turn any PDF into an editable Word document in seconds.
PDF pages have no fixed pixel dimensions — they are defined in points (1 point = 1/72 of an inch). When converting to an image, the tool renders the page at a chosen resolution measured in dots per inch (DPI):
| DPI | Use case | Typical file size (A4 page) | |-----|----------|-----------------------------| | 72 | Screen display, thumbnails | ~150 KB | | 150 | Web publishing, email | ~400 KB | | 300 | Print-ready, professional sharing | ~1.5 MB |
For most purposes — sharing on the web, embedding in presentations — 150 DPI is the sweet spot between sharpness and file size. For printed outputs or when the image will be enlarged, use 300 DPI.
Converting a Specific Page (Not the Whole Document)
If you only need one page, enter that page number in the page range field before converting. This saves time and gives you a single image file without needing to extract it from a ZIP.
Converting Scanned PDFs to Images
Scanned PDFs are already images wrapped in a PDF container. Converting them back to JPG/PNG extracts those images directly. The output quality depends on the quality of the original scan — PDFlexa does not upscale or enhance the source image.
If the scanned PDF has text you need to make editable, use PDFlexa's OCR tool instead, which uses optical character recognition to extract text from scanned pages.
Use Cases for PDF-to-Image Conversion
- Social media: Most platforms don't support PDF files. Convert a one-pager or infographic to JPG and share it directly.
- Presentations: Insert a PDF page as an image into PowerPoint or Google Slides.
- Email previews: Attach a JPG thumbnail alongside the full PDF so recipients see the content at a glance.
- Website content: Embed a page from a brochure or report as an image without linking to the full document.
- Archiving: Convert old PDF records to TIFF or PNG for long-term archiving systems that require image formats.
Frequently Asked Questions
Does converting a PDF to JPG lose quality? JPG uses lossy compression, so there is some quality reduction compared to the original. For sharp text, use PNG (lossless) or a high DPI setting for JPG. For scanned pages with photos, JPG at high quality (85–95%) is indistinguishable from the original.
Can I convert a PDF with multiple pages to a single image? Not directly — each page becomes a separate image file. If you need multiple pages combined into one tall image, you would need an image editor to stitch them together after conversion.
What is the maximum number of pages I can convert at once? PDFlexa processes the conversion in your browser, so there is no server-side limit. Performance depends on your device — very large PDFs (100+ pages at high DPI) may take a few minutes on slower machines.
Will the images have a transparent background? Only if you choose PNG format. JPG does not support transparency and renders transparent areas as white.
Is it safe to convert confidential PDFs? Yes. PDFlexa converts files entirely in your browser using JavaScript. Your file is never uploaded to any server, so confidential documents stay on your device throughout the process.
