Convert PNG to PDF
PNG is a lossless format with transparency support, ideal for graphics, logos and screenshots. Converting to PDF wraps the picture in a document instead of an image file, which is what printers, email attachments and upload portals tend to expect. The conversion runs entirely in your browser: there is no upload, no file size limit and no watermark on the result.
Drop your PNG files below and download PDF in seconds. Free, unlimited and completely private: the conversion runs inside your browser, so your files never leave your device and are never uploaded to a server.
No upload. Works with your network switched off. Check it yourself, or read what actually happens to your file.
Why convert PNG to PDF?
PNG stores every pixel exactly as it was saved, which makes it the safe choice whenever detail matters more than file size. It supports a full alpha channel, so logos and UI elements keep clean, soft edges on any background. The tradeoff is that photos saved as PNG can get large.
PDF is the universal format for documents that must look identical everywhere. Wrapping images in a PDF makes them easy to print, email or archive as a single file, and every operating system can open the result without extra software.
Note that PDF does not support transparency, so any transparent areas in your PNG files will be filled with a solid background after conversion.

What changes when you convert PNG to PDF
| What happens | |
|---|---|
| Image quality | Slightly reduced. The image is embedded in the PDF as JPEG at quality 0.92, which is visually close but not identical. |
| Transparency | Lost. PDF cannot store an alpha channel, so transparent areas are filled with solid white. |
| EXIF and GPS | Removed. The conversion goes through a pixel buffer, so camera data and location are not carried into the PDF file. |
| Colour profile | Not carried across. The image is handled in sRGB, which is right for the web and wrong for colour-managed print work. |
| Animation | Not applicable. PNG files here are single images. |
| File size | Varies with the content of the image. No figure is quoted here, because none has been measured on a documented test set. |
