Frequently Asked Questions

What happens to transparent PNGs?
You can set a white background, a custom color, or leave it transparent. jsPDF renders the PNG directly onto the PDF page so transparency is handled cleanly.
Can I upload screenshots and diagrams?
Absolutely. PNG is the perfect format for screenshots, UI mockups, charts, and diagrams because it preserves sharp edges and text without compression artifacts.
Is there a limit on how many PNGs I can convert?
There is no hard limit in the tool. For very large sets of images, performance depends on your device's browser memory. We recommend batches of up to 50 images for best results.
Does the tool support Auto orientation?
Yes! The Auto mode detects whether each image is wider than it is tall (landscape) or taller (portrait) and sets the page orientation accordingly — great for mixed batches.

PNG to PDF Converter — Complete Guide

PNG images are popular for screenshots, logos, graphics, and any content that requires transparency or lossless quality. Converting PNG files to PDF preserves this quality while creating a universally compatible document that can be emailed, printed, or archived without loss.

💡 Preserve transparency

PNG supports transparent backgrounds. Our converter handles transparent PNGs cleanly, placing them on a white page background in the PDF.

💡 Great for screenshots

PNG is the standard format for screenshots. Converting multiple screenshots to a single PDF is perfect for bug reports, tutorials, and documentation.

💡 Lossless quality

Unlike JPG, PNG uses lossless compression. Your PDF will retain every pixel of detail from the original PNG file.

💡 Combine with other formats

Need to mix PNG and JPG images in one PDF? Simply upload both types together — our tool handles both formats simultaneously.

PNG (Portable Network Graphics) was created as an open, patent-free alternative to GIF. It supports 24-bit color and full alpha transparency, making it the preferred format for web graphics, UI screenshots, and images with text. PDFs generated from PNG images are ideal for technical documentation, software manuals, and design presentations where sharpness and clarity matter most.
