How to convert PNG to PDF online
PNG is the most common format for screenshots, exported diagrams, design mockups, and graphics with transparent backgrounds. When you need to share several PNG files as one cohesive document — for a client, a course submission, or an application — converting them to PDF is the right move. PDFTask's PNG to PDF converter handles this instantly in your browser, with no file upload to a server.
PNG vs JPG — does it matter for PDF conversion?
Both work equally well. PNG files support transparency, which gets rendered with a white background in the final PDF (since PDF pages are solid white by default). JPG files are typically smaller for photographic content, while PNG is preferred for graphics with sharp edges or text, since it uses lossless compression. Either way, both convert cleanly into PDF pages.
How to use this tool
- Drop your PNG images onto the upload zone, or click to browse for them.
- Add multiple files at once — they'll each become a page in the final document.
- Click Convert & download PDF.
For converting JPG photos instead, JPG to PDF uses the same engine and also accepts PNG, so either tool works for mixed batches. To view the resulting PDF immediately after conversion, open it in the PDF Viewer.
