Frequently Asked Questions

PDFtoPNG.co uses advanced browser-based technology to convert your PDF files to PNG images entirely on your device. When you upload a PDF, our JavaScript-powered converter processes it using PDF.js library, renders each page to a canvas, and generates high-quality PNG images. Everything happens in your browser - no files are uploaded to our servers.

Absolutely safe! We never store, access, or see your files. All processing happens entirely in your web browser using client-side JavaScript. Your PDF files never leave your device, and PNG outputs are generated locally. We don't collect personal information, track usage, or store any file data on our servers.

There are no server-imposed file size limits since we don't upload files to servers. The only limitations are your device's available memory and browser capabilities. Most modern devices can handle PDFs up to several hundred megabytes. For very large files, ensure you have sufficient RAM and close other browser tabs for optimal performance.

Yes! Our batch processing feature allows you to convert multiple PDF files simultaneously. Simply drag and drop multiple PDFs or use the file selector to choose several files. Each PDF will be processed independently, and you'll get progress indicators for each conversion. You can download all converted images at once or individually.

Our converter produces high-quality PNG images with 150 DPI resolution by default, which is suitable for most use cases. The quality depends on your original PDF's resolution and content. Vector graphics and text in PDFs convert to crisp, clear PNG images. For photos and complex graphics, quality matches the original PDF source.

PDFtoPNG.co works on all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. We require JavaScript to be enabled and use HTML5 features like Canvas API and File API. For the best experience, use the latest version of your preferred browser. Internet Explorer is not supported.

Conversion speed depends on several factors: PDF file size, number of pages, complexity of content, and your device's processing power. Large PDFs with many pages or high-resolution images take longer. Complex vector graphics also require more processing time. Try closing other browser tabs and applications to free up system resources.

Currently, our converter processes all pages in a PDF file and generates PNG images for each page. You'll receive individual PNG files for every page, which you can then select and use as needed. We're working on adding page selection features in future updates.

Yes, PDFtoPNG.co is completely free with no hidden costs, premium plans, or feature limitations. We believe essential document conversion tools should be accessible to everyone. There are no daily limits, file size restrictions, or watermarks on your converted images.

If conversion fails, try these steps: 1) Ensure your PDF isn't password-protected or corrupted, 2) Check if your browser supports JavaScript and has enough available memory, 3) Try a smaller file or fewer pages, 4) Refresh the page and try again, 5) Try a different browser. If problems persist, contact our support team.

We use minimal essential cookies only for website functionality and security. We don't use tracking cookies, advertising cookies, or analytics that collect personal information. You can disable cookies in your browser settings without affecting the conversion functionality.

Yes! We also offer PNG to PDF conversion. You can combine multiple PNG images into a single PDF document with customizable page sizes, orientations, margins, and quality settings. Visit our PNG to PDF converter page to access this feature.
