PNG to PDF Converter

Q: How do I convert PNG to PDF?

Drop your PNG files onto the PDFfans converter, arrange them in the order you want, choose a page size, then click Convert to PDF. Your browser builds the PDF locally in seconds. No upload, no signup, no watermark.

Q: How do I merge multiple PNGs into one PDF?

Drop all your PNG files together or add them one by one, drag thumbnails to reorder, then click Convert. Every image becomes a page in the same PDF in the exact sequence shown.

Q: Does converting PNG to PDF reduce quality?

No. PNG is lossless, so the image in the PDF is identical to the original. Transparency is also preserved — no white backgrounds appear.

Q: Is my PNG file safe? Do you upload it?

No. The converter runs entirely in your browser. Your files never leave your device and are never sent to any server.

Q: How do I convert PNG to PDF on iPhone or Android?

Open this page in Safari or Chrome, tap Choose Files, select your PNGs, then Convert. The PDF downloads to your device. No app needed.

Q: Which is better — PNG or PDF?

PNG is ideal for single graphics with transparency. PDF is a document container for sharing or printing multiple images as one file.

Q: Can I combine PNG and JPG files into one PDF?

This tool accepts PNG only. Convert JPGs separately with the JPG to PDF tool, then merge both PDFs with the Merge PDF tool.

Additional Information

Convert PNG to PDF in your browser — free, private, transparency preserved

Drop one PNG or a whole folder of them onto this page and get a single PDF back in seconds. This PNG to PDF converter runs entirely inside your browser — your images never leave your device, never touch our servers, and never sit in someone else's cloud. Drag, drop, reorder, convert. Done.

Works on Chrome, Firefox, Safari, and Edge. Desktop, laptop, iPhone, Android — no app to install, no account to create, no watermark on the output.

Why convert PNG to PDF this way

Most online converters upload your PNG files to a remote server, queue them, process them, then let you download the result. That round trip leaks your images to a third party and adds unnecessary wait time. This tool skips all of that. JavaScript running in your browser reads each PNG and builds the PDF locally — the file never crosses the network.

Transparency stays intact

PNG is the go-to format when you need a transparent background — logos, icons, UI mockups, design assets. When you convert PNG to PDF here, that transparency is preserved in the output. No surprise white boxes behind your artwork.

Real use cases

Design portfolios. Combine logo variations, UI screens, or illustration sets into one PDF for client review or job applications.
Scanned documents. Phone-scanned receipts, contracts, or forms saved as PNG? Merge them into a single shareable PDF.
Screenshots and tutorials. Turn a sequence of annotated screenshots into a step-by-step PDF guide.
Academic submissions. Students merge hand-drawn diagrams or whiteboard photos into one PDF to upload.
ID and certificate scans. Sensitive documents that should never leave your device — this tool keeps them local.

Quality you can trust

PNG is a lossless format, so the image you drop in is the image that ends up in your PDF — no re-compression, no quality loss, no surprises. Page size defaults to A4, but you can choose Letter, A3, A5, Legal, or "Fit to Image" so every page matches its PNG's exact dimensions with zero white borders.

Merge and reorder before you convert

Drop multiple PNGs at once and drag the thumbnails to set the page order. Add more images anytime, remove the ones you don't need, then hit Convert. The PDF assembles every image in the exact sequence shown on screen.

How this compares to other tools

iLovePDF, Smallpdf, and Adobe's online converter all require uploading your files to their servers. That works for non-sensitive images, but it means your PNGs sit on someone else's infrastructure — even if briefly. PDFfans processes everything client-side: same output quality, zero upload, zero server storage, zero queue. If your images are JPG instead of PNG, switch to our JPG to PDF converter — same privacy, same workflow.

What if I have a mix of PNG and JPG files?

This tool accepts PNG only, so the conversion stays clean and predictable. For JPG images, use our JPG to PDF tool. If you need to combine both into one document, convert each batch separately and then merge the two PDFs with our Merge PDF tool.

After you convert

Need a smaller file? Run the output through Compress PDF. Want to lock it with a password? Protect PDF adds AES-256 encryption — also in your browser. Every tool on PDFfans works the same way: locally, privately, free.

How to Use

Drop your PNG files. Click "Choose Files" or drag PNG images into the drop zone. Add as many as you need.
Reorder if needed. Drag the thumbnails to set page order. Click the trash icon to remove any image before converting.
Choose page settings. A4 fits most needs. Switch to Letter, A3, or "Fit to Image" for exact dimensions. Set orientation to Auto for mixed portrait and landscape images.
Click Convert to PDF. Your browser builds the PDF locally — no upload, no waiting queue.
