PNG to PDF: Convert PNG Images to PDF Documents
📸 Live preview — Combine PNG images into a single PDF document.
Why Convert PNG to PDF?
PDF (Portable Document Format) is the universal standard for document exchange. Converting multiple PNG images into a single PDF makes it easier to share, store, and print collections of images — such as scanned pages, presentations, photo albums, or receipts. PDF files are smaller than the sum of individual PNGs and can be opened on any device without image compression.
Use cases: combine several scanned PNG documents into one PDF for emailing; turn a set of design mockups into a client-friendly PDF portfolio; or convert screenshot sequences into a readable manual. Our tool uses the jsPDF library to create a PDF with each PNG occupying one full page, preserving original dimensions and quality. All processing happens in your browser — no uploads, no waiting, and no privacy concerns.
Since PNG is lossless, your images remain sharp in the PDF. You can also use this tool to create a contact sheet or photo album. The generated PDF is standard PDF/A compliant and can be opened in Adobe Acrobat, Preview, Chrome, Edge, and all major browsers.
📌 How to Convert PNG to PDF (Step by Step)

⚙️ How the PNG to PDF Conversion Works
We use the jsPDF library (version 2.5.1) to create a PDF document dynamically. For each selected PNG, we load the image using an HTMLImageElement, then calculate its aspect ratio. The PDF page dimensions are set to match the image's width (scaled to fit within the PDF's page width, defaulting to A4 portrait if needed). The image is added to the PDF using pdf.addImage() with the appropriate scaling. After all images are added, the PDF is saved as a Blob and presented for download.
All image data stays in your browser's memory; no files are uploaded to any external server. The process is entirely client-side, ensuring privacy and speed. The resulting PDF maintains the original image's pixel dimensions and color depth (24-bit RGB).
