What does this PNG to PDF converter do?
This free PNG to PDF converter turns your PNG images into a single, clean PDF file — entirely in your browser. Select one PNG or a whole folder of them, arrange the page order, choose a page size and orientation, and download the finished document. No account, no installation, no waiting for a server.
Every part of the conversion happens locally using JavaScript and the Canvas API. Your images are never uploaded, never stored, and never shared. Transparent areas of your PNG files are rendered on a clean white PDF background so the pages look exactly the way they do on screen.
The PDF itself is assembled with jsPDF, an open-source library that generates PDF files directly in the browser. Each image is embedded at up to 3500 pixels on its longest side, so the pages look sharp on screen and in print while the PDF stays a sensible size.
How to convert PNG to PDF in 3 steps

Download your PDF
The PDF is built in your browser and downloads automatically as converted-images.pdf. If your browser blocks the download, click Download PDF.
Why convert PNG to PDF?
- One file instead of many. Sending a folder of loose PNGs is messy. A single PDF keeps everything together in the right order.
- Universal compatibility. PDFs open identically on Windows, macOS, Linux, Android, and iOS — the recipient does not need any special software.
- Better for printing. A PDF respects page size and orientation, so what you see on screen is what comes out of the printer.
- Required by many portals. Job applications, visa forms, university submissions, and government portals often accept only PDF uploads.
- Easier to archive. A PDF keeps your images in a stable format that will still open decades from now.
- Smaller than a folder of PNGs. Embedding PNGs into a PDF usually produces a file that is easier to email or upload.

PNG vs PDF: what is the difference?
PNG and PDF serve different purposes. PNG is a raster image format designed for graphics with sharp edges and transparency — logos, screenshots, icons, and illustrations. PDF, on the other hand, is a document format that can hold many pages, respects page size and orientation, and opens identically on every device.
| Feature | PNG | |
|---|---|---|
| Best for | Graphics, screenshots, logos, transparency | Documents, multi-page files, submissions |
| Number of images | One image per file | Many images, one file |
| Transparency | Supported | Rendered on white background |
| Page size & orientation | Not supported | Full control (A4, Letter, Legal, A3, A5) |
| Printing | Depends on printer settings | Consistent, exactly as designed |
| Best for upload portals | Sometimes accepted | Almost always accepted |
If you are sharing a single graphic, PNG is usually fine. If you are submitting a form, uploading to a portal, printing a document, or sharing more than one image, PDF is almost always the better choice. This converter lets you get the benefits of PDF while keeping the visual quality of your original PNG files.
Tips for the best PNG to PDF results
- Start with good source images. The PDF embeds your PNGs at up to 3500 pixels on the longest side, so a sharp original produces a sharp page.
- Match orientation to the image. If most of your PNGs are wide, choose landscape; if they are tall, choose portrait. Mixed batches work fine too — each image is fitted individually.
- Use "Contain" for documents. This mode keeps the whole image visible and preserves the aspect ratio, ideal for screenshots and UI captures.
- Use "Cover" for photos. If you want each page completely filled with no white space, "Cover" fills the page and crops the overflow.
- Leave a margin for printing. A 10 mm margin prevents content from being clipped by the printer's unprintable edge.
- Order matters. The first card becomes page 1. Drag to reorder before converting so the pages come out exactly as you want them.
Is this PNG to PDF converter really private?
Yes. This is one of the few converters that never sends your images anywhere. Everything — reading the files, arranging the pages, drawing the images, and generating the PDF — happens locally in your browser using JavaScript and the Canvas API. There is no server component, no database, no upload endpoint, and no logging of your files.
You can verify this yourself. Once the page has loaded, disconnect from the internet and try a conversion. It will still work. That is only possible because nothing is being sent anywhere. When you close the tab, the images are released from memory and are gone for good.
This makes the tool safe for sensitive content such as ID cards, bank statements, medical records, signed forms, and personal screenshots — files you would never want to hand to an unknown server.
