HEIC to TIFF Converter — Free, Online, No Upload

HEIC photos from iPhone look excellent on Apple devices, but professional workflows — print houses, photo labs, archival systems, and scientific imaging platforms — often require TIFF as the delivery format. HEIC is a consumer camera format; TIFF is what professionals use when quality and compatibility with editing software both matter.

TIFF is the standard input format for print-ready workflows in Adobe InDesign, professional scanners, and archival databases. Major photo editors like Photoshop and Lightroom can export to TIFF with full layer support, but they need a TIFF to work with when interoperating with other tools. If you're sending images to a print lab, a magazine, or a medical imaging system, TIFF is the format they expect. It's also the best format for multi-page document scans and high-resolution artwork.

Converting HEIC to TIFF gives you a lossless result — the pixel data is preserved without any compression artifacts. File sizes will be substantially larger than the original HEIC: a 4 MB HEIC photo may become a 20–40 MB TIFF. That's expected and appropriate for archival or print use. If you just need to share the photo or post it online, convert to JPEG instead — TIFF is for workflows where quality cannot be compromised.

Typical sizes (12MP photo): HEIC 1.5–3 MB → TIFF 20–70 MB.

TIFF will not bring back detail that HEIC compression already removed, but it adds no further loss — handy when you need to edit the image.
