PNG to PDF: Step-by-Step Guide
To use PNG to PDF, open the PNG to PDF tool, choose your file, and it processes and saves the result right in your browser — nothing is uploaded. It's free, needs no sign-up, and works on both desktop and mobile.
PNG to PDF lets you convert PNG images into a PDF — useful for combine screenshots into a single shareable PDF and similar everyday document tasks, without installing any software.
What Is PNG to PDF?
PNG to PDF is iLikePDF's free, browser-based tool to convert PNG images into a PDF. It runs entirely on your device using your browser's own processing power, so there is no waiting on a server and no file leaves your device for this task.
How to Use It — Step by Step
- Open the PNG to PDF tool and choose your file (or drag & drop it onto the upload box).
- Check any on-page options relevant to this tool.
- Click the main action button and let it process in your browser.
- Download the finished file to your device and open it to check the result.
Why Use This Tool?
- Convert PNG images into a PDF without installing any software.
- No need to sign up or pay to use it.
- Processing happens locally in your browser, not on a remote server.
- Free to use as many times as you need, with no watermark.
Supported File Formats
PNG to PDF accepts: One or more PNG images.
Is It Safe and Private?
PNG to PDF runs its processing in your browser using your device's own resources. The tool code does not make an upload request for the file you select, so your file is not sent to a server for this task. Keep in mind that no tool can guarantee what happens after you download and share the resulting file elsewhere — that depends on where you send it next.
Best Practices
- Keep a copy of your original file until you have checked the converted result.
- Check the output carefully — page count, image quality, text accuracy or page order, depending on the tool.
- Test with a smaller, non-confidential file first if your real file is very large or sensitive.
- PNG transparency is flattened onto a white background in the PDF page.
