Can I merge multiple HEIC photos into one PDF?

Converting HEIC photos to PDF creates a universally readable document that maintains consistent layout on any device, operating system, or printer. iPhone users routinely photograph receipts, contracts, whiteboards, and paperwork - All captured as HEIC by default - And then hit a wall when the recipient can't open the files. A PDF opens identically on Windows, macOS, iOS, and Android with no codec or extra software.

A single PDF can contain dozens of pages, each holding a separate image at full quality. This is particularly valuable when digitising multi-page documents: photograph each page with your iPhone, upload all the HEIC files at once, and the converter merges them into a single ordered PDF in seconds.

Page size matters for print. A4 (210 × 297 mm) is the international standard used in Europe, Asia, and most of the world. US Letter (8.5 × 11 in) is standard in North America. If your photo dimensions do not match the page exactly, the image is scaled proportionally to fill the page. Choose the page size that matches your printer or the recipient's expectations.

Reasons to convert HEIC to PDF usually come down to compatibility, file-size, or specific feature requirements. Common situations:

• An app or platform only accepts PDF uploads.
• You need a feature unique to PDF (e.g. transparency, vector scaling, animation, multi-page pages, etc.) that HEIC doesn't provide.
• You're optimising file size — modern formats often produce smaller files than the older format you started with.
• You need a single archival format across a project so files behave consistently in the same viewer.

1. Open the HEIC → PDF tool on heic.now.
2. Drag your HEIC file onto the drop zone, or click Select files. You can drop a whole folder of files at once.
3. The output is fixed to PDF. If the format supports extra options (page size, transparency background, quality, EXIF stripping), tweak them in the right-hand panel.
4. Click Convert. The job runs on our server and finishes in a few seconds for typical photos.
5. Download the result. Files stay in storage for 24 hours and are then permanently deleted.

The entire flow is free for the first 10 jobs per day with no signup required. A free account doubles that quota; a premium plan removes the limit entirely.

• Upload photos in the exact order you want them to appear - Pages are ordered by upload sequence.
• Modern iPhone HEIC photos are 12–48 MP, which is far more than enough resolution for sharp print output on A4 or Letter pages.
• Choose A4 for most international recipients; choose Letter for North American printing.
• If the PDF will be bound or hole-punched, add a margin so content isn't obscured.
• Compress your HEIC files first if the final PDF must stay small (e.g. for email attachments) - This reduces per-page image data.
