HEIC a PDF

Yes. Both .heic and .heif extensions are accepted, including HEIF screenshots and photos from iPhones and iPads. Files with any other extension are skipped when you add them.

HEIC is heavily compressed, and the converter decodes each photo to a lossless PNG before placing it in the PDF at full resolution, so a 12 megapixel photo can take tens of megabytes. Run the result through Compress PDF if you need a smaller file.

Each photo becomes its own page in the order listed. The page is sized to the photo's pixel dimensions at one point per pixel, so a 4032 by 3024 photo produces a page about 56 by 42 inches, which viewers and printers scale to fit.

No. The decoded image is stored as plain pixels, so location, camera model, and capture date from the phone aren't carried into the PDF.

Only the first image in the container is converted; additional frames stored in the same file are ignored. For a Live Photo, the still image is used and the video part, which lives in a separate .mov file, isn't involved.

The HEIC decoder is libheif compiled to WebAssembly and loads in the browser when first needed. Later conversions in the same session skip that step, though large photos still take a few seconds each to decode.

Not here; this tool accepts only HEIC and HEIF. Images to PDF accepts HEIC alongside JPG, PNG, WebP, and other formats in a single batch.

No. Decoding and PDF creation happen in your browser, so private photos never leave your phone or computer.
