HEIC to PDF

Take the HEIC photos straight off your iPhone and stack them into a PDF, one image per page.

Everything happens on your device — your files are never uploaded.

What this does

HEIC is the photo format iPhones and recent iPads save by default. This tool decodes each HEIC (or HEIF) file into raw pixels, re-encodes it as a PNG, and writes the images into one PDF, one image per page.

Each page is sized to its image exactly, so nothing is cropped or scaled and the original orientation is kept. The image data is decoded losslessly into the PDF; pixel-level quality matches the source. The decode and encode both happen in your browser, so the files never leave your device.

How it works

  1. 1 Drop your HEIC images.
  2. 2 Each one gets decoded and dropped into a single PDF, one image per page.
  3. 3 Download the PDF.

Frequently asked

Why does the first conversion take a moment? +

The HEIC decoder is about 3 MB and downloads the first time you use it. After that it's cached, so conversions are quick.

What page size and orientation are used? +

Each page is sized to fit its image exactly. Nothing gets cropped or scaled, and pages keep the original orientation.

Does the conversion lose quality? +

The pixels are decoded from the HEIC and embedded as PNG, which is lossless, so the image in the PDF matches the source pixel for pixel. HEIC itself is usually compressed, but this tool doesn't recompress or downscale the picture.

Are my photos uploaded anywhere? +

No. Decoding and PDF building run entirely in your browser, and nothing is sent to a server. There's no sign-up and no watermark.

Can I convert several photos at once? +

Yes. Drop as many HEIC files as you like and they're combined into a single PDF in the order you added them, one image per page. There's no fixed limit beyond your device's memory.

What happens to Live Photos, depth, and other metadata? +

Only the still image is converted. A Live Photo's motion and audio are ignored, and EXIF fields like GPS and capture date aren't carried into the PDF. Orientation is applied so the image isn't rotated.

Does it keep transparency? +

If a HEIC has an alpha channel it's preserved through the PNG step, but a PDF page has no transparent background, so transparent areas render against the page.

Which browsers work? +

Any modern browser that runs WebAssembly, including ones on systems that can't open HEIC natively, since the decoder is bundled rather than relying on the OS.
