How to convert PNG to PDF
- Drag your PNG files into the box above or click “Choose files” (folders and pasting from the clipboard work too).
- PDF is preselected as the output format; adjust quality, size and target file size if you like.
- Press “Start converting”; files are converted in your browser, in parallel.
- Download the files one by one or grab them all as a ZIP.
Why convert PNG to PDF?
PDF is the right choice for sending, printing or archiving images as documents; each image becomes a one-page PDF at its own size, or you can combine all images into a single PDF.
If a PNG has transparency it is kept when the target format supports it; otherwise the background colour you pick is used.
PNG may contain transparency; because PDF does not support it, transparent areas are filled with the background colour you choose (white by default).
PNG vs PDF

| Compression | Lossless | Depends on embedded image |
| Transparency | Yes | No |

| Typical file size | Large (for photos) | Medium |

PNG is a lossless format with full transparency (an alpha channel). PDF is a document format for sharing content that looks the same on every device; images are embedded as pages. It is not suited to image editing and cannot be shown directly as an image on web pages.
Tips for the best results
- By default each image becomes its own PDF. To put them all in one PDF, tick “Combine all images into one PDF” in the settings (you can pick A4 or image-sized pages).
- For the web, limiting the width to 1600 pixels cuts file size a lot while keeping visual quality (Resize section).
- Metadata such as GPS location and camera details (EXIF) is always removed from the output.
Privacy and security
Conversion runs entirely in your browser (using WebAssembly); your images are never uploaded to our server and never leave your device. The server only receives anonymous counters that contain no file names or content (source/target format, size, duration). Metadata such as location and camera details is always stripped from the output.
