How to convert PNG to PDF
PNG files are great for crisp screenshots, diagrams, and graphics, but they are harder to share in formal contexts than a PDF. Many submission forms, email clients, and document workflows expect PDF. Converting your PNG to PDF wraps the image in a standard document container that displays consistently everywhere and can be printed at the correct dimensions.
BoltConverter embeds your PNG into a PDF page sized to match the image, preserving the full resolution without recompressing the image data. You can upload multiple PNGs and merge them into a single multi-page PDF, one image per page. The conversion runs on our servers and your files are deleted as soon as the download completes.
