PNG is the go-to format for screenshots, diagrams, UI designs, and any image requiring lossless quality. But PDFs are what the professional world runs on — required for email attachments, document portals, legal submissions, and archived records. This tool bridges the gap instantly.

Frequently Asked Questions
Why would I convert PNG to PDF instead of keeping it as PNG?
PDFs are the universal standard for document exchange, printable at any size without pixelation, and supported by every document management system. Converting PNGs to PDF is ideal when you need to submit screenshots as a professional document, combine multiple diagrams into a single deliverable, or archive images in a format that preserves layout and is universally readable.
Are PNG transparency and alpha channels preserved in the PDF?
When a PNG with a transparent background is embedded into a PDF, the transparent areas typically render as white in most PDF viewers. Full alpha channel transparency in PDF requires specific PDF transparency group settings. For transparent PNGs, we composite onto a white background before embedding to ensure consistent rendering across all PDF viewers.
Can I combine screenshots with different sizes into one PDF?
Yes. Each image becomes its own page, sized to match the image dimensions. Images of different sizes result in pages of different dimensions in the final PDF — this is intentional and correct PDF behaviour. If you need uniform page sizes, enable the normalise to A4 option before converting.
