Why convert PNG to PDF
PNG is the format diagrams, screenshots, UI exports and logos come in — PDF is the format they need to be to attach to an application, submit with a form, or print. This is the bridge, done locally: your screenshots and diagrams never cross the network.
One thing to know up front: PDFs built here flatten transparency onto a white background. A PNG logo with a transparent centre will get a white centre — exactly what print and most viewers want. If you need the transparent area to stay transparent, keep the PNG; PDFs for print almost always want the white.
How to do it (3 steps)
- Add your PNGs — screenshots, diagrams, logos, in order.
- Check the page order.
- Download the PDF — flattened to white where the PNG was transparent.
Technical note
Like the JPG route, each PNG is embedded without re-encoding, so the PDF size is close to the sum of the PNGs. For text-heavy screenshots that is usually still far smaller than a re-scanned version would be. If you are bundling many flat-graphics PNGs and size matters, convert them to WebP first — the PDF pipeline accepts the result either way.
The mistake worth avoiding
The common mistake is the same weight trap as the JPG route, plus one more: PNG screenshots of a full desktop at high resolution can be 5–10 MB apiece. If the PDF is for a bug report or an application, the receiver needs to read it, not inspect it at the pixel level — crop to the relevant area rather than the whole screen, and the PDF becomes instantly shareable. The other quiet mistake: assuming transparency survives. It becomes white. That is usually what you want, but check before sending a logo document.
FAQ
- What happens to transparent parts of my PNG? They are flattened to white in the PDF. That is the standard for documents and print.
- Are the PNGs uploaded? No — assembly happens entirely in your browser.
- Why not just send the PNGs in a ZIP? Many forms and workflows require a single PDF; a ZIP of images is often rejected or forces the receiver to do work you could do in ten seconds here.
- Can I mix PNGs and JPGs in one PDF? Here each source type has its own route, so for a mixed set build two PDFs or convert everything to one format first. The finished document does not care which route its pages came from.
