When to use PNG to PDF

A product manager has signed-off wireframe screenshots saved as PNGs — one per screen — and needs to hand the design team a single PDF to mark up together in Adobe Acrobat. Drop all the PNGs here, drag them into user-flow order, and pdf-lib embeds each image on its own page directly on your computer, preserving the lossless quality and any transparency in the source files. The same approach works when you're archiving screenshot-based instructions as a permanent document or submitting multiple graphics through a procurement portal that only accepts PDF attachments. Nothing is uploaded — the conversion runs in this browser tab from start to finish, and the finished PDF downloads immediately and opens in any reader without extra plugins.

  • Archive signed-off wireframe PNGs as a single PDF for design review
  • Submit multiple graphic assets through a portal that only accepts PDF
  • Package screenshot-based onboarding instructions into a shareable guide

About this tool

PNG images preserve transparency and detail — this tool puts them into a PDF without any quality loss. Upload one or more PNGs, drag them into the order you want, and a single PDF downloads immediately. Useful for packaging wireframes or mockups into a shareable document, combining screenshot-based instructions into a guide, or submitting multiple graphics to a form that only accepts PDF. No signup, no watermark. Conversion runs locally in your browser, so image files stay on your device from start to finish.
