Converting PNG to PDF wraps an image — a screenshot, diagram, receipt, or scanned page — into a document that prints cleanly and uploads to virtually any form. In our sample set, PDF files ran about 7% larger than the PNG source. PDF preserves the image as-is and is accepted where raw image files often aren't, which makes it the right format for paperwork and printing. Drop several PNGs to package them together. Everything happens in your browser, so sensitive documents never leave your device.

Best practices for PNG → PDF
Concrete settings to pick before you convert PNG to PDF.
- Always preview the PDF output before bulk-downloading — colour shifts, transparency surprises, and quality artifacts show up in the preview before they ship.
- Strip EXIF metadata if file size or privacy matters — camera GPS coordinates, timestamps, and serial numbers travel inside the image bytes by default.
- For photographic content, target a PDF quality between 80 and 85 — that's the sweet spot where most encoders stop showing visible artifacts and the file size curve flattens.
- Verify the alpha channel rendered as expected — premultiplied vs straight alpha and edge halos around antialiased pixels are the most common surprises when going to PDF.
