Is my AVIF uploaded to a server?

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

Does image quality change?

Opaque AVIF images embed as high-quality JPEG (quality 90); AVIF 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

AVIF is the newest, most efficient format, the smallest files of all, with transparency and wide-gamut color. AVIF is still rare in document workflows; 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.
