About PNG to PDF
PNG to PDF keeps the complete file workflow inside this browser tab. Your selected file, its name, contents, settings, and generated output are not sent to AntiUpload or a cloud conversion service. Ads and aggregate traffic analytics stay outside the processing boundary and receive no file object or working buffer.
AntiUpload's PNG to PDF converter merges one or more PNG images into a single PDF without uploading them. Great for screenshots, diagrams, or transparent graphics you want bundled as a document.
All processing is client-side, so your images stay on your device. Add multiple PNGs, order them, and download one clean PDF.

Frequently asked questions
Are my images uploaded?
No — they're combined in your browser and never sent to a server. Input files are read from browser memory and the output is created locally for your download. AntiUpload does not send file bytes, names, sizes, page counts, contents, passwords, or generated outputs through analytics or advertising requests.
What happens to PNG transparency?
Transparent areas are placed on a white page background in the PDF.
Can I reorder pages?
Yes — arrange the images before converting to set the page order.
Any limits or watermarks?
None — free, no sign-up, no watermark, no daily caps.
Can I convert multiple PNGs to PDF at once?
Yes. Add as many PNG files as you like and they're combined into a single PDF in the order you arrange them, so you can batch a large set of images at once.
Does this work on Windows, Mac, iPhone, and Android?
Yes. It runs entirely in your web browser, so it works the same on Windows, Mac, iPhone, and Android with no app to install.
Will converting PNG to PDF reduce the image quality?
No. Your PNGs are embedded into the PDF as-is without re-compression, so the images keep their original quality. Because everything happens in your browser, the files are never uploaded.
