Why convert PNG to PDF?
- Turning a screenshot of a confirmation page or receipt into a PDF for expense filings.
- Saving a PNG export from Figma, Sketch, or Photoshop as a PDF for a client review.
- Converting a scanned document (PNG output from a flatbed scanner) into PDF for upload.
- Sending a PNG of a chart, diagram, or whiteboard to someone who'd prefer a PDF.
- Wrapping a transparent PNG as a single-page PDF for inclusion in a larger document.
- Making a printable proof from a high-resolution PNG render.
How our converter works
Your PNG is embedded into a new PDF document via pdf-lib's embedPng, with the page sized to the image's pixel dimensions exactly. PNG transparency is preserved (rendered against the PDF page background, which is white by default). The original PNG bytes are embedded losslessly. Conversion runs entirely in your browser.
Frequently asked questions
Will transparency come through?
Mostly. PDF supports image transparency, and pdf-lib preserves the alpha channel when embedding. The page background is white by default, so transparent areas appear white when printed or viewed.
Will the PNG be recompressed?
No — the PNG bytes are embedded directly into the PDF. The output preserves your original image quality exactly.
Can I convert multiple PNGs into one PDF?
Not yet from this single-file tool. Convert each PNG to PDF separately, then use the merge-pdf tool to combine them into one document.
Are my files uploaded?
No. pdf-lib runs as JavaScript in your browser. Screenshots, design exports, and scanned documents stay on your device.
About the PNG format
PNG is the lossless raster format — what screenshots, vector tool exports (Figma, Sketch, Illustrator), and high-quality scans typically come as. PDF is the universal document format — what most document workflows expect. Converting PNG → PDF is the standard step when a high-fidelity image needs to live in a document context: a screenshot for an expense report, a design export for client review, a scan for archival. The conversion is lossless and the PDF is single-page, sized to match the original image dimensions.
