Open Tool →What Is TIFF and Why Does It Matter?
TIFF (Tagged Image File Format) has been the gold standard for lossless image storage in professional workflows since the 1980s. Unlike formats designed for compact web delivery, TIFF prioritizes pixel fidelity above file size. Every pixel is stored exactly as decoded — no palette limits, no lossy compression, no generational quality loss when you save and re-save. This makes TIFF the format of choice for print production, professional photo editing, scanning workflows, and any situation where the image will be color-corrected, retouched, or printed at high resolution.
TIFF supports full-color 24-bit RGB imagery, optional alpha channels, and 16-bit per channel for HDR work. The uncompressed variant produced by this tool opens in every application that supports TIFF without any codec requirement — from Adobe Photoshop to GIMP to Windows Photo Viewer to professional RIP (raster image processing) software used in commercial printing.
What Is HEIC and Where Does It Come From?
HEIC (High Efficiency Image Container) is the default photo format used by iPhones and iPads since iOS 11. It stores images using the HEVC video codec (also known as H.265), which achieves roughly twice the compression efficiency of JPEG while maintaining comparable visual quality. A HEIC photo from a 12-megapixel iPhone camera typically occupies 2–4 MB, whereas an equivalent JPEG might be 5–8 MB.
The trade-off is compatibility. While Apple devices open HEIC natively, Windows requires a Microsoft Store codec extension, and many professional imaging and print workflows do not support HEIC as an input format. Linux support is limited. Web browsers have added varying degrees of native HEIC support, but it is not universal. For any workflow beyond the Apple ecosystem, converting HEIC to a more universally supported format — like TIFF — is often necessary.
When Should You Crop and Convert HEIC to TIFF?
- Delivering to a print production workflow. Commercial printing workflows almost universally require TIFF or high-quality JPEG. If your source photo is a HEIC from an iPhone, this tool converts it to print-ready TIFF in seconds — with the option to crop to the exact content area needed for the layout.
- Archiving iPhone photos in a universally readable format. HEIC is efficient for device storage, but TIFF is far more durable as a long-term archive format. Every major imaging application will be able to open an uncompressed TIFF in ten or twenty years; the same cannot be said with certainty for HEIC.
- Preparing images for color correction or retouching. TIFF is the preferred input format for color grading and retouching tools because it passes the full decoded pixel data with no further loss. If you need to color-correct an iPhone HEIC photo, converting to TIFF first gives your editing software the best possible starting point.
- Extracting a specific subject from a photo. The crop tool lets you isolate a portrait, product, or detail from a larger HEIC photo and export just that region as a clean, lossless TIFF — without needing Photoshop.
- Supplying assets for magazine or book layouts. Publications and design agencies commonly request TIFF source files. The crop step lets you frame the image correctly and deliver a properly sized TIFF rather than a full-resolution uncropped file.
HEIC vs TIFF: Format Comparison
| Property | HEIC | TIFF |
|---|---|---|
| Compression type | Lossy HEVC (or lossless mode) | Uncompressed or lossless LZW/ZIP |
| Color depth | 10-bit HDR support | 24-bit RGB, 32-bit RGBA, 48-bit HDR |
| Transparency | Yes — full alpha channel | Full 8-bit alpha channel |
| File size (photo) | Very compact — 2–4 MB for 12MP | Large — 30–60 MB for 12MP |
| Print production support | Not universally supported | Industry standard |
| Platform compatibility | Native on Apple; codec required elsewhere | No codec required — opens everywhere |
| Editing without quality loss | Lossy after re-encode | Yes — no generational loss |
| Best for | iPhone storage, Apple workflows | Print, archiving, professional editing |
How the Crop Workflow Works in the Browser
The HEIC to TIFF Crop Converter decodes your HEIC file entirely in the browser using a two-stage approach. First, it attempts native HEIC decoding via createImageBitmap() — available in Chrome 105+, Safari, and Edge. If native support is not available, it automatically falls back to the heic2any JavaScript library, which uses a WebAssembly-based HEVC decoder for full cross-browser compatibility. The decoded image is drawn onto an HTML5 Canvas element, and an SVG overlay renders the crop rectangle and handles on top.
When you drag a handle, the tool maps canvas coordinates back to the original image's pixel dimensions using a scale factor (natural width ÷ display width). This ensures the crop is applied at full resolution — the canvas is only a display proxy. When you click Convert & Download TIFF, an off-screen canvas draws only the selected region using drawImage with source rectangle parameters. The tool reads the raw RGBA pixel data with getImageData and manually encodes a valid TIFF binary using a baseline little-endian IFD structure. No server round-trip is required at any point.
What the TIFF Encoder Produces
The encoder produces a baseline TIFF (Revision 6.0 compatible) with the following characteristics: little-endian byte order, uncompressed pixel storage (Compression tag = 1), RGB photometric interpretation (tag = 2), 8 bits per sample per channel, 3 samples per pixel, resolution set to 72 DPI. This profile is the broadest possible TIFF subset — it opens without issue in Photoshop, Lightroom, GIMP, Affinity Photo, Preview, Windows imaging tools, and commercial RIP software. The file does not use JPEG compression or any proprietary extension.

Does cropping a HEIC photo before saving as TIFF improve quality?
Cropping selects a region and discards the rest. The quality of the selected pixels is fixed by the original HEIC encoding — HEIC uses lossy HEVC compression by default on iPhones, so some detail compression is already present. The TIFF encoder stores those decoded pixels without any further compression or lossy step, so from the point of conversion forward you have a lossless file. The TIFF step cannot recover fine detail that HEVC compression already smoothed out, but it preserves exactly what the decoded HEIC contains.
How large will the output TIFF be compared to the HEIC?
Uncompressed TIFF stores 3 bytes per pixel (RGB). A 4000×3000 crop produces a TIFF of approximately 36 MB of pixel data plus a small header. A comparable HEIC from an iPhone might be 3–5 MB. The TIFF will be significantly larger — this is expected and reflects the uncompressed lossless storage. If file size is a concern after converting, open the TIFF in Photoshop or GIMP and re-save with LZW compression, which can reduce TIFF file size by 40–70% for photographic content.
Can I use the output TIFF in Adobe Photoshop or Lightroom?
Yes. The output TIFF is a standard baseline TIFF that opens directly in Photoshop, Lightroom, GIMP, Affinity Photo, and any other professional imaging application. No special import settings are required. The file appears as a standard 8-bit RGB TIFF layer.
Is the conversion really free with no file size limit?
Yes. Because all processing runs entirely in your browser, there is no server to impose a limit. The only practical limit is your device's available RAM. There are no usage caps, no watermarks, and no account required.
What happens to the HEIC's HDR or wide color data during conversion?
iPhone HEIC photos captured in HDR or wide color (Display P3) mode contain color data beyond the standard sRGB gamut. The browser's Canvas API renders this data into a standard 8-bit-per-channel sRGB surface. The TIFF encoder then captures those 8-bit values. HDR headroom beyond the standard dynamic range is tonemapped during the browser decode step, not by this tool. The output TIFF represents the image as the browser renders it — which for most practical purposes matches what you see on screen.
