    Done

    Your files are processed on this device and never sent to a server. Reload the page to clear everything from memory.

    Photograph a document with an iPhone and you get a HEIC file that Windows, many web forms and most email clients cannot show. A PDF sidesteps all of that. This page decodes each HEIC with libheif compiled to WebAssembly, running in your tab, then writes the photos into a PDF as JPG pages at high quality.

    Add every page of the document as a separate photo and reorder them with the arrows; the PDF keeps that order. Pick A4 or Letter with a small margin for forms and contracts, or "Fit to each image" to keep every photo at its own size.

    How it works

    1. Drop HEIC or HEIF photos from an iPhone or iPad, or tap to pick them.
    2. Choose the page size, orientation and margin. Reorder pages with the arrows.
    3. Convert. The PDF downloads from your browser with nothing sent anywhere.

    In your browser, not on a server

    JPG and PNG images are embedded directly into the PDF by pdf-lib without re-encoding. Other formats are decoded by your browser (HEIC via libheif) and embedded as JPG or PNG. Page size, orientation and margins are applied while laying out each page in memory.

    Compared with upload-based tools: Uploading a folder of receipts or ID scans to make one PDF is exactly the kind of thing that should not need a server. The PDF is assembled on your device in the time it takes to pick the files.

    Verify it yourself. Load this page, turn off Wi-Fi or switch to airplane mode, and run the tool. Or open your browser's developer tools (F12, or Cmd-Option-I on a Mac), pick the Network tab, and watch it while you convert. The panel above does the same count for you.

    Questions

    Why can I not attach HEIC photos to a form?

    HEIC is the format iPhones have used since iOS 11. It is compact, but many websites and Windows programs only accept JPG, PNG or PDF. Converting to PDF is the safest option for documents.

    Is the photo quality kept?

    The HEIC is decoded to pixels and re-encoded as JPG at quality 92 inside the PDF, which is visually identical for photographed documents. For a lossless copy, convert to PNG first and then use the PNG to PDF page.

    Does the PDF contain the photo location?

    No. Decoding the HEIC discards its EXIF block, including GPS, so the PDF carries no camera or location data.

    Is the file uploaded anywhere?

    No. There is no server in this process. The page is a static file and the work is done by code running inside your browser tab. You can load the page, turn off Wi-Fi, and it still works.
