Does converting TIFF to HEIC reduce quality?

TIFF files are the professional standard for scanned documents, medical imaging, satellite imagery, and publishing workflows. They preserve every pixel at full depth (often 16 bits per channel) and can be very large - A scanned A4 page at 600 DPI as TIFF is typically 50–150 MB. Converting to HEIC reduces this to a few megabytes, thanks to HEVC compression that is roughly twice as efficient as JPEG.

HEIC is an unusually good target for high-quality TIFF masters because it supports 10-bit colour - Where a JPG export would crush 16-bit tonal data down to 8 bits, HEIC retains substantially more of the original tonal range. That makes TIFF→HEIC attractive for personal archives of scans and edited photographs where storage matters but quality should degrade as little as possible.

Multi-page TIFFs (used for multi-page scanned documents) require special handling. Each page can be extracted as a separate HEIC, similar to converting a multi-page PDF. As always with HEIC, verify the destination: Apple devices and modern Adobe tools open it natively, but legacy publishing systems and Windows without the HEVC codec will not.

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

• An app or platform only accepts HEIC uploads.
• You need a feature unique to HEIC (e.g. transparency, vector scaling, animation, multi-page pages, etc.) that TIFF 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 TIFF → HEIC tool on heic.now.
2. Drag your TIFF 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 HEIC. 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.

• Use quality 90%+ when converting professional TIFF images to preserve maximum detail in the HEIC output.
• HEIC's 10-bit support preserves more of a 16-bit TIFF's tonal range than an 8-bit JPG would - But for true archival masters, keep the original TIFF.
• If your TIFF file has multiple pages, each page is extracted as a separate numbered HEIC.
