What you can do with PNG to PDF
Converting PNGs to PDF places your images into a PDF document, one per page, keeping crisp graphics and text in a format that is easy to send and print.
Bundle screenshots
Combine several PNG screenshots into one PDF to share a walkthrough or a bug report.
Convert exported graphics
Turn PNGs exported from a design tool into a PDF for review or printing.
Make images printable
Put PNGs into a PDF so they print at a predictable page size.
Share diagrams as one file
Group charts or diagrams into a single document instead of many separate image files.
A more secure model for PNG to PDF
The weakest point in most online PDF workflows is the round trip to a server: the upload can be intercepted, the server can be compromised, and copies can linger in logs, caches, or backups long after you are done. Adding TLS helps in transit, but it doesn't protect the copy that ends up sitting on the provider's disk.
ContinuePDF's approach is to not send the file anywhere. The convert logic runs inside your browser's sandbox, isolated from other sites and from the wider system. Your PNG images exist only in your device's memory while the tool works, which shrinks the attack surface to essentially zero — there is no server component to breach.
Why choose ContinuePDF
No transmission
The file is never sent over the network, so it can't be intercepted.
No retention
Nothing is stored server-side — no logs, caches, or backups of your file.
Sandboxed
Processing runs inside the browser's isolated security sandbox.
Minimal surface
No server component means there is nothing on our side to attack.
Pro tip
Arrange your PNGs in the order you want the pages before converting. Images with transparent backgrounds sit on a white page in the PDF, so check that light-coloured content is still visible against white.
Frequently asked questions
Can I combine multiple PNGs into one PDF?
Yes. Add as many images as you like and they become consecutive pages, in the order you arrange them.
What happens to transparent areas in my PNGs?
Transparent regions render against the PDF page background, usually white, so the image appears flattened onto the page while keeping its sharpness.
How is this more secure than other PNG to PDF tools?
Most tools upload your file to a server, creating a copy that can be intercepted, logged, or breached. ContinuePDF processes your PNG images inside your browser, so the document is never transmitted and no server-side copy is ever created.
Are my files stored anywhere after I convert them?
No. Because the file never leaves your device, there is nothing stored on our end. The document lives only in your browser's memory during processing and is cleared when you close the tab.
Is ContinuePDF free to use?
Yes. ContinuePDF and all of its tools, including PNG to PDF, are free with no signup required. Because documents are processed in your browser rather than on our servers, we can offer the full feature set at no cost.
