What is PDF to Image Conversion?
PDF to image conversion transforms PDF pages into raster image formats like PNG or JPG. This process, called rasterization, converts vector graphics and text into pixel-based images. It's useful for creating thumbnails, sharing document previews, embedding in presentations, or when you need images instead of PDF format.
- Convert each PDF page to separate image file
- Support for PNG (lossless) and JPG (compressed) formats
- Adjustable resolution/DPI for quality control
- Maintains aspect ratio and page dimensions
- Batch conversion for multi-page PDFs
- Preserves visual appearance of original PDF
- No quality loss with PNG format selection
- 100% Client-side processing: Files are converted in your browser
Why Convert PDFs to Images?
Image formats offer universal compatibility and easier sharing compared to PDFs. Converting to images enables use in platforms that don't support PDF embedding, creates thumbnails for galleries, and simplifies document previews. We prioritize your privacy by performing all conversions locally on your device—no file uploads required.
How to Use
- Upload PDF file (multi-page supported)
- Select format: PNG (lossless) or JPG (smaller size)
- Choose resolution: 72 DPI (web), 150 DPI (standard), 300 DPI (print)
- Preview generated images before downloading
- Download individual images or bulk zip archive
- File names include page numbers for easy organization
- Original PDF remains unchanged on your device
PDF to Image Conversion Glossary
- Rasterization
- The process of converting vector graphics (PDF) into pixel-based raster images (PNG/JPG).
- DPI (Dots Per Inch)
- Resolution measurement determining image quality; higher DPI = sharper images but larger file sizes.
- PNG Format
- Lossless image format supporting transparency, ideal for graphics, text, and when quality is paramount.
- JPG/JPEG Format
- Lossy compressed image format optimized for photographs and when smaller file sizes are needed.
- Vector Graphics
- Scalable graphics defined by mathematical equations (PDFs often contain vector elements) rather than pixels.
- Lossless Compression
- Image compression that preserves all original data, resulting in perfect quality (PNG uses this).
- Lossy Compression
- Compression that discards some data to achieve smaller file sizes, potentially reducing quality (JPG uses this).
- Batch Conversion
- Converting multiple PDF pages or files to images in a single operation for efficiency.
