Frequently asked questions
Is PNG to PDF really lossless?
Yes. PNG is a lossless format and it is embedded in the PDF without re-encoding to JPEG, so screenshots and diagrams keep every pixel exactly.
What happens to transparent areas?
Transparency is kept in the embedded image. On screen and on paper it shows over the white page, which is what you almost always want.
Why is my output PDF large?
Lossless quality has a cost: detailed photos stored as PNG are big. If size matters more than perfect fidelity, convert photos with the JPG to PDF tool instead.
Is it safe to use this tool with confidential documents?
Yes — and verifiably so. PDFAgent has no upload step: your file is processed by JavaScript running in your own browser and never leaves your device. You can open your browser’s network panel (or even go offline after loading the page) and confirm that no document data is transmitted.
