PDF is the standard format for sharing documents professionally. If you have a PNG — a screenshot, a photo, a scanned signature, a diagram — converting it to PDF makes it easier to share, easier to print, and compatible with every system that accepts document uploads.
Filero's Image to PDF tool converts PNG images to PDF directly in your browser. Nothing is uploaded to a server, the conversion is instant, and you can combine multiple images into a single document.
How to convert PNG to PDF for free
Open Filero's free Image to PDF tool and follow these steps:
- Upload your PNG file or files. You can select multiple images at once.
- Reorder the images by dragging if needed — the order you set is the order they appear in the PDF.
- Click Convert to PDF.
- Download your PDF.
The entire process runs in your browser using JavaScript. Your images are never sent to a server.
Common reasons to convert PNG to PDF
Submitting images as documents. Many online forms and portals only accept PDF uploads — job applications, insurance claims, government forms, university submissions. Converting your PNG to PDF resolves the compatibility issue immediately.
Combining multiple images into one file. If you have several screenshots, scanned pages, or photos that together make up a document, merging them into a single PDF is far more manageable than attaching five separate image files.
Preserving layout for printing. PNG files render differently on different printers. A PDF preserves the layout, scale, and margins precisely — what you see on screen is what prints.
Sending a scanned signature or ID. Scanned documents are often saved as PNG or JPEG. Converting to PDF makes them look more professional and compatible with document management systems.
PNG to PDF versus JPG to PDF — is there a difference?
Not meaningfully, for most purposes. Both PNG and JPG images embed into the PDF in the same way — as compressed image data inside the document container. The PDF quality will match the quality of the source image regardless of whether it was PNG or JPG.
The one practical difference: PNG supports transparency, and when you convert a PNG with a transparent background to PDF, the transparent areas become white in the PDF (since PDF pages have white backgrounds). If you need transparency preserved, save the image in a vector format like SVG before embedding, or use a tool that supports transparent PDF layers.
Other ways to convert PNG to PDF
On Windows:Open the PNG in Microsoft Photos or Paint, press Ctrl+P to print, and select "Microsoft Print to PDF" as the printer. Save the output as a PDF file. This is quick for a single image but does not support combining multiple images easily.
On Mac:Open the PNG in Preview, go to File > Export as PDF. For multiple images, select them all in Finder, open them together in Preview, then go to File > Print and choose "Save as PDF" from the PDF dropdown in the print dialog.
On iPhone:Tap the image in Photos, tap the Share icon, scroll down and tap "Print", then pinch outward on the preview to get the PDF — share or save it from there. Alternatively, use Filero in Safari.
Frequently asked questions
Can I convert multiple PNGs into one PDF?
Yes. Upload multiple PNG files in the Image to PDF tool, arrange them in the order you want, and they will all be combined into a single PDF — one image per page.
Does the conversion reduce image quality?
No meaningful quality loss occurs during the conversion. The image is embedded in the PDF at its original resolution. The PDF file size will be similar to the original PNG.

Yes — the Image to PDF tool accepts JPG, PNG, WebP, BMP, and other common image formats.
