How to Convert HEIC to PDF with PDFgear

HEIC is the default photo format on many iPhones and iPads. It keeps files small, but many people and systems cannot open it, and a PDF is easier to share, print or attach to a form. PDFgear includes a converter for turning HEIC images into PDF. This guide covers preparing the files, running the conversion, checking the result and fixing the usual problems.

Before you start

• Copy the HEIC files to the computer or device where you will use PDFgear, and keep the originals. Conversion creates a new file, but a backup lets you redo the job with different settings.
• Check the extension. Some photos named .heic are actually .heif or JPEG files, and some apps rename photos on export. If the converter rejects a file, the real format is the first thing to check.
• Decide whether you need one combined PDF or one PDF per photo, and in what page order. Renaming the files in order (for example 01, 02, 03) makes sorting easier.
• Choose where to run PDFgear. It is offered as a web converter and as installed apps, and the tools available can differ between versions and platforms. Use the version that lists HEIC to PDF on your system.

Where processing happens matters if your photos are private, such as ID documents, receipts or medical papers. A web converter may send your files to a server, while an installed app may do the work on your device. Do not assume either one. Before you convert sensitive images, read PDFgear's current privacy policy and the description of the tool you are using. Look for whether files are uploaded, how long they are kept and how they are deleted.

Step-by-step instructions

• 1. Open PDFgear and find the HEIC to PDF converter. In the web version it is a separate converter tool. In an installed app, look among the conversion tools. Labels and placement can change between releases.
• 2. Add your HEIC files using the file picker or by dragging them in. If you want a single document, add all the images together.
• 3. Check the order of the images. If the tool lets you reorder or remove files, set the page sequence now.
• 4. Review any page options the tool offers, such as page size, orientation, margins or merging into one PDF. Your version may have only some of these options, or none.
• 5. Start the conversion and wait for it to finish. Large batches or high-resolution photos take longer.
• 6. Download or save the PDF. Choose a new file name so you do not overwrite an earlier version, and keep the original HEIC files until you have checked the result.

Page settings are the main thing that changes how the result looks. A fixed page size such as A4 or Letter is better for printing and forms, but it can add white borders or shrink the photo. Fitting the page to the image keeps the full photo but gives pages of different sizes. If the result looks wrong, run the conversion again from the originals with different settings. You do not need to edit the PDF.

Check the output

• Open the PDF in a different viewer from the one that created it, so you know it opens elsewhere.
• Count the pages and confirm the order matches the photos you added.
• Zoom in on text in photographed documents. If the text was readable in the original but not in the PDF, the image was compressed or scaled down.
• Check that each page is the right way up and that nothing is cut off at the edges.
• Compare the PDF's file size with the originals. A much larger or much smaller file is a reason to look more closely at quality and page settings.
• If the PDF is going to someone else, consider whether it should include photo details such as location or capture time. Formats handle this data differently, so check the document properties in your PDF viewer.

Some HEIC features do not carry over to a standard PDF page. A Live Photo becomes a single still image. A file holding several frames or a burst may convert only its main image. HDR and wide-colour photos may look flatter or slightly different on screen. For a photographed document this rarely matters, but compare colours if accuracy matters to you.

Common problems and next steps

The file is rejected or will not upload. Check that it really is HEIC or HEIF and is not damaged. One quick test is to open it in a photo viewer that supports HEIC. If it opens there, try converting a single file first. A very large batch, or an interrupted transfer from the phone, can cause the failure.

Windows cannot preview the HEIC file. This is a Windows viewing limitation, not a problem with the photo. Windows may need an extra HEIF codec from the Microsoft Store before File Explorer and Photos can display HEIC. You may still be able to add the file to the converter without it.

Photos appear rotated in the PDF. Phones often store orientation as a tag instead of rotating the image itself, and not every tool reads that tag. Rotate the affected pages in a PDF editor, or rotate and resave the photo before converting it again.

You got several PDFs instead of one, or the reverse. Check whether your version has an option to merge images into a single document. If it does not, merge the separate PDFs afterwards with a PDF merge tool.

The PDF is too large to email or upload. Convert fewer images per file, or compress the finished PDF, then check text readability again. Compression can make small print harder to read.

You want to avoid HEIC in the future. On an iPhone, go to Settings > Camera > Formats and choose Most Compatible to save new photos as JPEG. Settings > Photos > Transfer to Mac or PC > Automatic converts photos when you copy them to a computer. Neither setting changes photos you have already taken.
