Is my PNG file uploaded to a server?

No. The entire conversion happens inside your browser using the pdf-lib JavaScript library. Your file never leaves your device.

What size will the PDF be?

The PDF page dimensions match the pixel dimensions of your PNG image exactly (in points, 1 px = 1 pt). The image fills the entire page with no margins.

Can I convert a JPEG or WebP instead?

This tool accepts PNG files only. For JPEG files, use the JPG to PDF converter. pdf-lib's native PNG embedding ensures lossless quality for PNG inputs.

Does transparency in my PNG carry over to the PDF?

Yes. pdf-lib embeds PNG images with their alpha channel, so transparent areas remain transparent in the resulting PDF.

Is there a file size limit?

There is no enforced server limit because nothing is uploaded. However, very large PNG files (above ~50 MB) may be slow to process depending on your device's memory and speed.
