HEIC Image to PDF format converter tool

This is a free online tool to convert a HEIC format image file into PDF format.

What Is HEIC Encoding Format?

HEIC (High Efficiency Image Coding) is a file format used for storing images and image sequences. It was developed by the Moving Picture Experts Group (MPEG) and is part of the High Efficiency Image File Format (HEIF) standard. Here are some key points about the HEIC format:

  • Compression Efficiency: HEIC is known for its superior compression efficiency compared to older formats like JPEG. It can store images at a much smaller file size without compromising quality.
  • Image Quality: Despite the smaller file sizes, HEIC images maintain high quality. This is because HEIC uses advanced compression techniques similar to those used in the H.265 video compression standard (also known as HEVC - High Efficiency Video Coding).
  • Multiple Images and Sequences: HEIC can store multiple images in a single file. This makes it suitable for burst photography and live photos (such as those used in Apple devices), where a series of images or short video clips are captured.
  • Support for Advanced Features: HEIC supports a range of features including transparency, 16-bit color depth, and HDR (High Dynamic Range) imaging. This allows for more detailed and vibrant images.
  • Adoption: HEIC is widely adopted in the Apple ecosystem, with iOS and macOS using it as the default image format for photos. However, support on other platforms and devices can vary. Windows 10 and later versions have support for HEIC, but it may require additional codecs to be installed. Android's support has been increasing but also depends on the specific device and OS version.
  • Conversion: Given its relatively new introduction and varied support across platforms, converting HEIC files to more universally accepted formats like JPEG or PNG is often necessary for compatibility. Various tools and libraries are available to facilitate this conversion.

In summary, HEIC is a modern image format that offers significant benefits in terms of file size and image quality but may require conversion for compatibility with all devices and platforms.

Why should we convert HEIC to PDF?

Converting HEIC to PDF is often necessary for compatibility and sharing purposes. HEIC is a modern format with limited support across all devices and platforms, while PDF is widely recognized and accessible. PDFs preserve image quality, are ideal for document management, and can be easily viewed, printed, and shared across various systems. This conversion ensures that images are accessible to a broader audience without compatibility issues.

What is the difference between HEIC and PDF file?

HEIC (High Efficiency Image Coding) is an image format known for its superior compression and high quality, used mainly for storing photos and image sequences. PDF (Portable Document Format), on the other hand, is a versatile document format that can include text, images, and other multimedia elements. PDFs are used for creating, viewing, and sharing documents across different platforms. While HEIC is optimized for images, PDF is designed for documents, offering features like text searchability, annotations, and fixed formatting.

Can I download converted PDF File?

Yes, this tool is completely free to use. You can download converted PDF file using the download button that appears after conversion.

Are my photos converted on client side or server side?

In this tool, photos are converted on the client side. The HEIC to PNG conversion is done directly in the user's web browser using the heic2any library. The converted image is then processed by the jsPDF library to create a PDF, all without needing to upload the file to a server. This approach ensures user privacy and reduces server load but relies on the user's device capabilities for processing.

How HEIC image file is converted to PDF file?

Steps to Convert HEIC to PDF

  1. The user selects a HEIC file using an input element.
  2. The heic2any library converts the HEIC file to a PNG Blob.
  3. A FileReader reads the PNG Blob and loads it into an HTML Image element.
  4. The jsPDF library creates a new PDF document.
  5. The image is added to the PDF using pdf.addImage().
  6. The PDF is saved and downloaded using

All processing occurs on the client side in the browser.

What is PDF Format?

PDF (Portable Document Format) is a versatile file format used for creating, viewing, and sharing documents independent of software, hardware, or operating systems. It preserves document formatting, including text, images, fonts, and layouts, ensuring consistency across devices. PDFs support interactive elements like forms and hyperlinks, are secure with encryption options, and can be easily printed or viewed using free PDF readers, making them ideal for digital documents, reports, forms, and eBooks.

Can HEIC to PDF Conversion Work on Mobile Browser (mweb)?

Yes, the conversion from HEIC to PDF as demonstrated in the client-side JavaScript example can work on a mobile browser, provided that:

  1. Browser Support: The mobile browser supports the necessary JavaScript APIs used in the example (FileReader and handling Blob objects).
  2. Library Compatibility: The libraries used (heic2any for HEIC to PNG conversion and jsPDF for PDF creation) should be compatible with mobile browsers.
  3. Device Performance: Mobile devices should have sufficient processing power and memory to handle the conversion, especially for large HEIC files.
  4. User Interaction: Mobile browsers typically allow users to select files from their device, enabling them to initiate the conversion process as shown in the example.

Overall, with these conditions met, the conversion from HEIC to PDF can work seamlessly on a mobile browser, offering flexibility and convenience for users on the go.
