Convert PNG to PDF
Combine one or more PNG images — screenshots, scanned pages, or transparent logos — into a single PDF file. Reorder the images, choose page orientation, and export a ready-to-share document, all processed locally in your browser.

Why convert with PNG to PDF instead of desktop software?
- 🖼️ Turn PNG screenshots, scanned documents, or exported design files into a single shareable PDF instead of attaching images one at a time.
- 🔀 Combine several PNGs — and mix in JPGs too — reordering them before you convert instead of converting each image separately.
- 🔒 Images are combined locally in your browser, so screenshots of private dashboards or ID photos aren't sent to a server to become a PDF.
- 💸 Free, no sign-up, and no watermark stamped on the resulting file.

Where this comes up
A support agent takes three PNG screenshots of a customer's error message across different screens and needs to attach them as one document to a ticketing system that only accepts a single PDF per reply. Drop the three PNGs in, put them in the order the customer would see them, and convert — one PDF attachment instead of three separate screenshots to juggle.
How the conversion actually works
Each PNG is embedded directly into a new PDF page using pdf-lib's PNG decoder, which reads the image's pixel and transparency data in this tab and scales it to fit the page size and orientation you chose — no re-encoding to JPEG, so there's no extra compression artifact introduced. A PNG's alpha channel (transparency) is preserved in the embedded image data itself, but a PDF page has no background layer beneath it, so transparent areas typically display as plain white page background once opened — the same as printing a transparent PNG. Everything — reading the files, embedding them, and building the final PDF — happens in this browser tab; there's no upload step for any image.
What to know before you convert
- Transparent regions in a PNG are preserved in the embedded image data, but appear as plain white page background when the PDF is viewed or printed, since a PDF page itself has no transparency layer.
- Very high-resolution PNGs (large screenshots, scanned pages) take a little longer to embed and scale than a similarly sized JPG, since PNG data isn't compressed the same way — a batch of dozens of large screenshots is more of a memory load on an older phone.
- Page size follows the orientation you pick (portrait or landscape); each image is scaled to fit that page rather than matching the PNG's exact pixel dimensions.
- This is the same underlying tool as JPG to PDF — if you need to mix PNGs and JPGs in one document, either page handles both formats identically.
