Why Convert PNG to PDF?
Need to turn a screenshot, graphic, or design into a shareable document? Converting PNG to PDF wraps your image in a format that is accepted everywhere for official submissions, printing, and archiving. PDFs are the standard for documents that need to look the same on every device.
The conversion preserves your PNG at full quality — the image is embedded without re-compression. The PDF page size matches your image dimensions exactly. This makes it perfect for receipts, certificates, screenshots for documentation, and design exports.
LeanImg creates the PDF right in your browser without uploading your files. Your images never leave your device — no server, no cloud, no third party ever sees your data. Free and instant with no account required.
For the sharpest printed results, use high-resolution PNG files. If you need smaller PDF files, compress your PNG before converting. Need a photo format instead? Try PNG to JPG for universal compatibility.
