Open Tool →What You Will Learn
This tutorial walks through every feature of the HEIC to PDF Converter on Data Conversion Center. By the end you will know how to convert a single HEIC file to PDF, batch convert multiple files, choose the right page size for your use case, create a combined multi-page PDF, and download your results as a ZIP archive. Everything runs in your browser — no software to install, no account required.
Before You Start
You need:
- A modern web browser — Chrome, Firefox, Safari, or Edge (2022 or later)
- One or more
.heicor.heiffiles from your iPhone, iPad, or any HEIC-compatible camera - No account, no software, no payment
The tool works on desktop and mobile. On iPhone or iPad, you can pick files from your Photos library directly using the Browse Files button.
Step 1: Open the Converter
Navigate to dataconversioncenter.com/image-tools/heic-to-pdf/. You will see the drop zone at the top of the tool area, the options bar below it, and the Convert to PDF button. The button starts greyed out — it activates once you add files.
Step 2: Add Your HEIC Files
You have two ways to add files:
- Drag and drop. Drag one or more
.heicor.heiffiles from your file manager and drop them onto the drop zone. The border highlights blue while you drag over it. - Browse. Click anywhere on the drop zone (or the "Browse Files" link) to open your system file picker. You can select multiple files using Shift+click or Ctrl+click.
After adding files, thumbnails load automatically below the drop zone in the Input Files grid. Each card shows the file name, file size, and a status badge reading "Ready". The Convert button becomes active.
You can drop more files after the initial batch — they are added to the queue without replacing the existing files.
Step 3: Choose Your Page Size
In the options bar, use the Page Size dropdown to select how the PDF pages should be sized:
- Image Size (auto) — the default. Each PDF page is sized exactly to the pixel dimensions of the source photo. No cropping, no margins, no white space. Best for digital delivery and screen viewing.
- A4 — scales each image to fit within A4 page margins (210×297 mm). The image is centered on the page. Landscape photos automatically rotate the page to landscape orientation. Best for international printing.
- Letter — scales each image to fit within US Letter margins (8.5×11 inches). Best for North American printing and submissions to US institutions.
Step 4: Convert to PDF
Click the Convert to PDF button. A progress bar appears and tracks conversion file by file. Each status badge in the Input Files grid updates from "Ready" → "Converting…" → "Converted" (green) or "Error" (red).
Conversion speed depends on your device and the size of your photos. A typical 12-megapixel iPhone photo converts in under two seconds on a modern device. The tool processes files in batches of two simultaneously for maximum throughput.
When conversion finishes, a summary banner confirms how many files succeeded. The Output Files grid appears below with a download button on each card.
Step 5: Download Your PDFs
After conversion, four download options are available in the action bar:
Option A — Download Individual Files
Click the ⬇ Download PDF button on any card in the Output Files grid to download that file immediately. Each PDF is named after the original HEIC file with a .pdf extension.
Option B — Download All PDFs (Separate Files)
Click Download All PDFs in the bulk action bar. Each PDF is downloaded as a separate file in quick succession. Your browser may ask permission to download multiple files — allow it when prompted.
Option C — Download as ZIP Archive
Check the Download as ZIP checkbox, then click Download All PDFs. All converted PDFs are packaged into a single timestamped ZIP file named dataconversioncenter_heic_to_pdf_YYYYMMDDHHMM.zip. This is the most convenient option when converting many files.
Option D — Download as Combined Multi-Page PDF
Click ⊞ Combined PDF to merge all converted images into a single PDF document. Each image becomes one page, in the same order as the Input Files grid. The output file is named dataconversioncenter_heic_to_pdf_combined_YYYYMMDDHHMM.pdf. This is ideal for photo albums, event galleries, insurance submissions, or any scenario where you want one file instead of many.
Step 6: Start Over (Optional)
Click Start Over to clear all files and reset the tool completely. The drop zone reappears, all thumbnails are removed, and the Convert button resets to its initial state. You can immediately begin a new batch.
Troubleshooting
A file shows "Error" status
This usually means the file is not a valid HEIC/HEIF image. Common causes: the file was renamed with a .heic extension but is actually a different format, or the HEIC file is corrupted. Try opening the file in your Photos app to verify it is readable, then retry.
Thumbnails are not loading
HEIC decoding relies on your browser's built-in support or the heic2any library. On some older browsers, thumbnail generation takes a few extra seconds — wait before assuming a problem. If thumbnails never appear, try Chrome or Edge which have the broadest HEIC support.
The browser asks to download multiple files
When using "Download All PDFs" without ZIP mode, the browser downloads each PDF separately and may prompt for permission to run multiple downloads. Click "Allow" in the browser prompt. To avoid this prompt in future sessions, enable the ZIP option before downloading.
Combined PDF page order is wrong
The Combined PDF uses the same order as the Input Files grid, which reflects the order files were added. If you need a different order, click Start Over and add the files in your desired sequence before converting.
