Frequently asked questions

PNG to PDF Converter FAQ

Is the PNG to PDF converter tool free?

Yes. The tool is free to use and does not require an account.

Are my files uploaded to OceanofTools?

No. Processing runs locally in your browser, so the selected files are not uploaded to OceanofTools.

Does it work on mobile devices?

Yes, although large or complex files usually process more reliably on a desktop device with more memory.

Will transparent PNG backgrounds remain transparent?

The converter preserves PNG data where possible, but the final appearance can depend on the PDF viewer and page background.

Can I combine PNG and JPG files together?

This page accepts PNG files only. Use the JPG to PDF tool for JPG images.
