Convert HEIC to TIFF Online

TIFF (Tagged Image File Format) is the professional standard for print-ready images, archival photography, and publishing workflows. Unlike HEIC, TIFF is accepted by every prepress pipeline, scanner archive, and professional editor without codec hassles, and it supports lossless compression (LZW and ZIP), 16-bit colour depth, multiple colour spaces (RGB, CMYK, LAB), and multi-page documents.

When you convert a HEIC to TIFF, the HEVC compression applied at capture is not undone - The quality captured in the original HEIC is what ends up in the TIFF. However, the TIFF preserves that quality exactly with no further compression loss, making it safe to open, edit, and re-save multiple times without accumulating artefacts. HEIC's 10-bit colour also maps comfortably into TIFF's high bit depths, so wide-gamut captures survive the trip.

File sizes are considerably larger. An uncompressed TIFF of a 12 MP photo can easily reach 36 MB - Versus roughly 2 MB for the HEIC original. LZW compression reduces the TIFF with no quality loss. If file size is a concern and lossless quality is needed, PNG is a more practical choice for web distribution; TIFF is best reserved for print and archival contexts.

TIFF (Tagged Image File Format) was developed in 1986 by Aldus Corporation (later acquired by Adobe) to standardise output from desktop scanners. Its extensible tag system lets a single file describe colour profiles, multiple pages, layers, paths and 32-bit floating-point pixels — features that made TIFF the universal master format for print, publishing and archival imaging. The format is still maintained by Adobe and is mandated by the Library of Congress and most museums for digital preservation. For iPhone shooters, TIFF is the natural landing spot when a HEIC enters a print or archival pipeline: the decode is a lossless snapshot, and 16-bit TIFF has ample headroom for HEIC's 10-bit colour.

Photographers and print professionals convert HEIC to TIFF when iPhone or HEIF-camera photos enter a print production workflow. Commercial printers, magazine publishers, and photo labs typically require TIFF because it supports lossless compression, 16-bit colour depth, and ICC colour profiles - And because their prepress systems frequently cannot read HEIC at all.

Archivists and digitisation projects use TIFF for long-term storage. Converting a HEIC capture to TIFF produces a stable, standards-based master copy that can be re-processed, cropped, and colour-corrected indefinitely without accumulating the generational loss that repeated lossy saves cause.

Expect a significant size increase: TIFF trades HEIC's efficiency for editability and universal professional-software support. The usual pattern is to keep HEIC or RAW as the capture format and produce TIFF only for the specific images heading into print or archive pipelines.
