Is my WebP uploaded to a server?

No. The PDF is built entirely in your browser: your WebP never leaves your device, and there's no queue and no account.

Does image quality change?

Opaque WebP images embed as high-quality JPEG (quality 90); WebP transparency is kept by embedding losslessly as PNG.

What size is the PDF page?

Your choice: fitted exactly to the image (best on screen), or A4 with the image centered inside a margin (best for printing and form uploads).

About image to PDF

WebP is a modern web format that is typically 25-35% smaller than JPG or PNG at the same quality, with transparency. Many forms and uploads still reject WebP; as a PDF the same image is accepted everywhere documents go.

OptImg builds the PDF entirely on your device: nothing is uploaded, sideways camera shots come out upright, and you choose the page — shrink-wrapped to the image or centered on A4 for printing.
