How to Convert HEIC to PDF (Free, Online, Mac & Windows)

The easiest way to convert HEIC photos to PDF is a two-step process: first convert HEIC to JPG using PixelTools' HEIC converter, then combine the JPG images into a PDF using the Image to PDF tool. Both steps run entirely in your browser — nothing is uploaded to a server. For a single photo, download the JPG and use Image to PDF. For multiple HEIC photos, convert each to JPG, then combine them all into one PDF.

HEIC is the default photo format on iPhone, but it has limited compatibility outside Apple devices. PDF is universally supported on every platform, device, and application — making it the better choice in several situations:

Sharing documents: When you photograph a contract, form, or handwritten note, sharing it as a PDF looks professional and is universally openable. HEIC files often can't be opened on the recipient's device.

Combining multiple photos: If you took several photos of a multi-page document, PDF lets you package them into a single file. A set of HEIC photos is awkward to share; a single PDF is clean.

Email attachments: Most email clients and corporate mail systems handle PDF better than HEIC. Recipients with Windows PCs often can't open HEIC without installing an additional codec.

Printing: PDFs print predictably. HEIC files require compatible software to print, which many people don't have.

Archiving: PDF/A is an archival standard. Converting important HEIC photos to PDF ensures they'll be accessible without depending on Apple's ecosystem in the future.

Mac has built-in tools that handle HEIC natively, making the conversion straightforward:

Using Preview (recommended for single files): 1. Open the HEIC file in Preview 2. Go to File → Export as PDF 3. Name the file and click Save

Preview exports the photo as a PDF with the image filling the page. Note: the PDF page size matches the image dimensions, which may produce unusual proportions for a letter- or A4-sized document.

Using Finder for multiple files: 1. Select multiple HEIC files in Finder 2. Right-click → Quick Actions → Create PDF 3. A PDF containing all selected images (one per page) is created in the same folder

This is the fastest native method for combining multiple HEIC photos into one PDF on macOS.

Using Photos app: 1. Select photos in the Photos library 2. File → Print (⌘P) 3. In the print dialog, click the PDF button in the bottom-left corner → Save as PDF 4. Choose a location and click Save

Windows doesn't support HEIC natively unless you've installed the HEIF Image Extensions from the Microsoft Store. Here are the most reliable options:

Option 1 — Online converter (no software needed): Convert HEIC to JPG using an online tool like PixelTools, then use the Image to PDF tool to create the PDF. Works on any Windows version without installing anything.

Option 2 — Microsoft Photos (Windows 11 with HEIF codec): If you have the HEIF Image Extensions installed, open the HEIC in Photos, click the three-dot menu → Print, and in the print dialog select "Microsoft Print to PDF" as the printer. This saves the image as a PDF.

Option 3 — Adobe Acrobat: If you have Acrobat (paid), it can open HEIC files directly and export to PDF via File → Create → PDF from File.

Option 4 — IrfanView (free): IrfanView with its plugins can open HEIC files. Once opened, go to File → Save As and select PDF format.

Yes. The iPhone Files app and iOS Share Sheet make this straightforward:

Method 1 — Files app: 1. Open the Files app and navigate to the HEIC photo 2. Tap and hold → Quick Look (or just tap to open it) 3. Tap the Share icon → Print 4. In the print preview, pinch outward on the preview thumbnail 5. This opens a full PDF preview — tap the Share icon to save or share as PDF

Method 2 — From the Photos app: 1. Open the photo in Photos 2. Tap Share → Print 3. Pinch outward on the print preview to convert it to a PDF 4. Tap Share and choose Save to Files or send it directly

For multiple photos, select them all in Photos first, then use Share → Print. The pinch gesture works the same way and produces a multi-page PDF.

When converting HEIC photos to PDF, a few things affect the final file size and quality:

Intermediate format matters: If you convert HEIC → JPG → PDF, the JPG compression setting determines quality. At 90–100% quality, the loss is negligible. If you convert HEIC → PNG → PDF, you get lossless quality but larger files.

Resolution: HEIC photos from iPhone are typically 12MP or higher. A PDF containing a full-resolution photo can be 5–15 MB per page. If file size matters, resize or compress the image before creating the PDF.

Single-image PDFs vs multi-image PDFs: When combining many HEIC photos into one PDF, the file size adds up quickly. Consider compressing individual images before combining, or use a PDF compressor on the final output.

Page size in the PDF: Tools that embed photos directly into PDFs often set the page size to match the image dimensions. This may produce non-standard page sizes (e.g. 4000×3000 pt instead of 595×842 pt for A4). If you need standard page sizes, use a dedicated image-to-PDF tool that lets you choose paper size and orientation.

A few things make HEIC-to-PDF conversion smoother:

Name your files before converting. If you're combining multiple HEIC photos into a PDF, rename them in order (01.heic, 02.heic, etc.) before conversion — most tools sort files alphabetically, and sequential names ensure the correct page order.

Check the orientation. HEIC files from iPhone store rotation in metadata. Some conversion tools don't read this metadata correctly, producing sideways pages in the PDF. Preview on Mac handles this correctly. If pages come out rotated in another tool, rotate them before embedding.

Compress first if sharing by email. A 5-page PDF of full-resolution iPhone photos can exceed 50 MB. Run the result through a PDF compressor, or compress the HEIC/JPG images first, before creating the PDF.

Use PNG as an intermediate for text-heavy photos. If you photographed a document with text (a form, a whiteboard, a receipt), converting HEIC → PNG → PDF preserves sharpness better than the HEIC → JPG path, because PNG is lossless.
