Format Overview & Applications

Phone photos are often captured as HEIC to save device space, but a PDF page is easier to place in a form or an email attachment for review.

Technical Specifications & Codec Breakdown

The browser worker decodes the first still HEIC image with libheif to 8-bit RGBA, then canvas writes a PNG for the PDF; HEIC image sequences are rejected.

OS & Browser Compatibility

Phone photo apps and compatible browsers can open HEIC originals, while most document workflows accept the resulting PDF page as a review or print copy.

Useful info

Use a still HEIC photo rather than a burst or image sequence; this decoder accepts still-image brands and converts the first decoded image.

Format Comparison & Technical Specifications

A 4032×3024 still from a phone fits a 26.9×20.2 inch PDF page at 150 dpi.

Frequently Asked Questions

Does this keep HEIC HDR data?

The decoded pixels are delivered as 8-bit RGBA and then embedded as a PNG image; the PDF is not an HEIC HDR asset.

Can I convert an HEIC sequence or burst?

The worker rejects HEIC sequence brands. Convert an individual still image if you need a PDF page.
