Convert PDF to PNG Images Online Free
Convert every page of a PDF into a high-quality lossless PNG image.
How to Convert PDF to PNG in 3 Steps
- Upload your PDF. Drag and drop or browse for the PDF you want to export as PNG images. Any PDF up to 50MB is supported, including multi-page documents.
- Click "PDF to PNG". PDFTools renders each page of your PDF at 150 DPI as a lossless PNG image. PNG uses lossless compression, preserving every detail without the quality loss of JPG.
- Download your PNG images. Single-page PDFs produce one PNG file. Multi-page PDFs are packaged into a ZIP file with one PNG image per page, numbered sequentially.
Why Use PDFTools to PDF to PNG?
- Lossless quality — PNG is a lossless format — every pixel in the output matches the rendered PDF page exactly, with no compression artefacts or blurring that JPG can introduce.
- Transparency support — PNG files support transparent backgrounds, making them ideal for PDF pages with non-white backgrounds that need to be placed over other content.
- Ideal for designers — Graphic designers and web developers specifically use PNG for document screenshots, presentation slides, and any asset where pixel-perfect quality is required.
- ZIP for multi-page documents — All PNG images from a multi-page PDF are bundled into a single ZIP file for convenient download.
Frequently Asked Questions
What is the difference between PDF to PNG and PDF to JPG?
PNG uses lossless compression — the output image is identical to the rendered page with no quality loss but produces larger files. JPG uses lossy compression — smaller files but with slight quality reduction, especially noticeable on text and sharp edges. Use PNG when quality matters most; use JPG when smaller file size is a priority.
Do PNG images support transparent backgrounds?
Yes, PNG supports full alpha transparency. If your PDF has a non-white or transparent page background, the PNG output will preserve that transparency, unlike JPG which always has a solid background.
What resolution are the output PNG files?
Pages are rendered at 150 DPI, producing approximately 1240 × 1754 pixels for an A4-sized page. This resolution is clear and sharp for screen use and standard web display. For very high-resolution output, note that higher DPI means proportionally larger file sizes.
