What is PNG to PDF conversion?
PNG to PDF conversion takes one or more PNG images — screenshots, graphics, scanned documents, or transparent design assets — and combines them into a single PDF file, one image per page. It's especially common for design work, since PNG is the go-to format for anything needing crisp edges, transparency, or lossless detail, like logos, diagrams, and screenshots of text.
This tool converts entirely in your browser using pdf-lib, a JavaScript PDF library. Your PNG files are read locally, embedded into new PDF pages, and the finished document is handed back to you — nothing is ever uploaded to a server. That keeps the process fast and keeps your files completely private, whether you're converting a single screenshot or a folder of design mockups.
Because PNGs are embedded without any re-compression, image quality is fully preserved in the resulting PDF — an important distinction from lossy formats like JPG, where repeated conversion can degrade detail over time.
How to Convert PNG to PDF
01
Upload your PNG files
Click the drop zone or drag and drop your PNG images directly onto the page. Multiple files are supported, and you can add more at any time before converting.
02
Arrange the order
Each PNG becomes a page in the order shown. Use the ↑ ↓ buttons next to any image to move it until the sequence matches the document you want to create.
03
Choose your settings
Pick your page size, orientation, and margin. Fit Image works well for screenshots and graphics; A4 or Letter suits documents meant for printing.
04
Name and download your PDF
Give the file a name and hit Convert. Your PDF downloads instantly — PNG transparency is handled automatically and nothing is sent to a server.
Tips & Best Practices
🖼️ Fit Image for screenshots
Screenshots and design graphics usually look best with Fit Image, since it keeps the page proportions identical to the source PNG.
⬜ Know what happens to transparency
PDFs don't support transparent backgrounds the way PNGs do — transparent areas will render as white in the final document.
🔢 Set page order first
Reorder your images with the ↑ ↓ buttons before converting — it's much faster than trying to fix page order in a PDF editor afterward.
🗜️ Compress if needed
PNGs can be large files, especially screenshots. If your combined PDF is too big to email, run it through our PDF Compressor afterward.
Frequently Asked Questions
Yes — completely free with no sign-up required. There are no conversion limits, no watermarks, and no hidden fees. The tool is funded by ads, not by charging users.
Completely. All conversion happens inside your own browser using JavaScript. Your images are never uploaded to any server — they never leave your device. This is a key advantage over many other online converters.
PNG images are embedded directly into the PDF without re-compression, preserving full quality. Transparent backgrounds are handled gracefully — they will appear white in the PDF, which is standard PDF behaviour.
Yes. Upload multiple PNG images and they will each become a page in a single PDF. Use the ↑ ↓ buttons to set the page order before converting.
Fit Image creates a page the same size as each image — ideal for photos and screenshots. A4 is the standard international paper size. Letter is the US standard (8.5 × 11 in). Both A4 and Letter scale your image to fit while keeping original proportions.
The PDF format doesn't support alpha transparency the way PNG does. When a transparent PNG is embedded into a PDF page, the transparent areas are rendered as white. If you need to keep a specific background color, flatten the PNG onto that color before uploading.
Yes — screenshots are almost always saved as PNG, making this one of the most common uses for this tool. Upload your screenshot, choose Fit Image, and convert to get a clean, single-page PDF.
There's no fixed limit imposed by the tool. Since conversion happens on your own device, very large or numerous PNG files may take a little longer to process depending on your device's available memory.
Yes. This tool works fully on mobile browsers such as Safari and Chrome. Tap the drop zone to select images from your photo library or files app, then convert exactly as you would on desktop.
