Is my HEIC uploaded to a server?

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

Does image quality change?

The HEIC is decoded on your device and embedded as high-quality JPEG (quality 90), orientation corrected — visually identical.

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

HEIC is the efficient format iPhones shoot by default, small and high-quality but hard to open outside Apple. Most document uploads can't take HEIC at all; as a PDF your iPhone photo is accepted everywhere, decoded right on your device.

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.
