How it works
- Add your PNG files — drag them in or click to browse. JPG and WebP work here too.
- Reorder them with the arrows. Each image becomes one PDF page at its natural size.
- Click Convert and download the PDF.
Frequently asked questions
- What happens to transparent areas in my PNGs?
- They are filled with white. PDF pages have no concept of transparency to the page itself, so anything see-through in the PNG is composited onto a white background — which matches how the page would look printed. If you need a different backdrop, add it to the image before converting.
- Can I put several PNGs into one PDF?
- Yes. Add as many as you like, arrange them with the arrows, and the finished PDF follows that order with one image per page. This is the usual way to turn a folder of screenshots or a multi-page scan into a single attachment.
- Why is my PDF so large?
- PNG is a lossless format, so screenshots and scans stay big, and the PDF can only be as small as the images inside it. Ten full-resolution PNGs can easily make a 30 MB document. Running them through the compress or resize tool first — 1600 pixels wide is plenty for most documents — usually cuts the result dramatically with no visible change.
- Will the pages be A4 or Letter sized?
- Each page matches its image exactly, so nothing is cropped, stretched or padded with margins. Readers and printers scale pages to fit the paper automatically, so a mixed set of screenshot sizes still prints sensibly.
- Are my images uploaded anywhere?
- No. The PDF is assembled inside your browser and the download comes from your own device. Nothing is transmitted to a server.
About this tool
PNG is what screenshots, exported diagrams and many scanners produce, and PDF is what people are asked to send. This tool bridges the two: drop in your PNG files, put them in order, and download a single PDF with one image per page — no editor, no account, no watermark.
Each page is sized to its image, so nothing is cropped or stretched and a mixed batch of screenshot dimensions still comes through faithfully. Transparent regions are flattened onto white, which is how the page would print anyway. JPG and WebP files are accepted alongside PNG, so you can mix a scan and a photo into the same document without converting them first.
One thing to expect: PNG stores pixels losslessly, which is excellent for crisp text but makes for heavy files, and a PDF is only as small as its contents. A dozen full-resolution screenshots can produce a document too large to email. Compressing or resizing the images first — around 1600 pixels wide keeps documents perfectly readable — is the quickest way to get a sensible file size, and JPG input generally yields the smallest PDFs when photographic quality is not critical.
Everything is built locally in your browser, so your images and the finished PDF exist only on your device. That is the right default given what usually goes into these files: ID scans, signed forms, receipts and screenshots of private accounts are not things to hand to a free upload service.
