TIFF → HEIC

Learn about the formats: What is HEIC? What is TIFF?

Convert TIFF raster images into the HEIC format effortlessly using our online tool. This conversion is essential for Apple device users looking to save storage space while maintaining visual clarity.

TIFF is a heavy raster image format traditionally used for professional printing and archival storage due to its uncompressed nature and massive file sizes. HEIC, on the other hand, is a modern raster format based on the HEVC standard, designed specifically for efficient storage on mobile devices. Because you are converting from a format without compression losses to a format with lossy compression, a portion of the original image data will be permanently discarded. However, the resulting HEIC file will typically become much smaller, making it significantly easier to share and store on iOS and macOS.

Since TIFF uses lossless encoding and HEIC relies on lossy compression, some image data is discarded during conversion, though the visual difference is often minimal to the naked eye.

Tips

Ensure your TIFF files do not contain complex multi-page layers that might not translate properly.
Check your Apple device compatibility, as older iOS versions may require third-party apps to view converted HEIC files.
Use this conversion primarily when you need to free up storage space rather than for archival purposes.

Common use cases

Transferring scanned documents and heavy photographs from a desktop archive to an iPhone or iPad.
Reducing the file size of heavy design assets so they can be easily shared via Apple Messages or AirDrop.
Optimizing large raster images for web deployment within Apple-centric ecosystems.

Why ConvertX stays free — forever

We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.

🎁

Free tools today — and always

Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.

🔒

Privacy-first processing

Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.

🖼️

Images

Raster and vector graphics for web, print, and photography.

Common extensions: PNG, JPG, WebP, AVIF, GIF, SVG, HEIC, TIFF

Advantages

+ WebP and AVIF offer excellent compression for the web
+ PNG keeps transparency and sharp edges
+ SVG scales without quality loss

Disadvantages

− RAW and TIFF files are large and slow to share
− JPEG loses quality on every re-save
− Some formats are not supported in older browsers

📄

Documents

Office files, PDFs, ebooks, and plain text.

Common extensions: PDF, DOCX, XLSX, PPTX, ODT, EPUB, TXT

Advantages

+ PDF locks layout for printing and sharing
+ DOCX and ODT are easy to edit collaboratively
+ Plain text works on any device

Disadvantages

− PDF is hard to edit without special tools
− Complex layouts may shift after conversion
− Scanned PDFs need OCR for editable text

🎬

Video

Clips, streams, screen recordings, and movies.

Common extensions: MP4, WebM, MOV, MKV, AVI, MPEG

Advantages

+ MP4 (H.264/H.265) plays almost everywhere
+ WebM is efficient for web embedding
+ MKV can hold multiple audio and subtitle tracks

Disadvantages

− High-resolution video needs lots of storage and bandwidth
− Re-encoding always takes time and may reduce quality
− Some codecs require licensing for commercial use

🎵

Audio

Music, podcasts, voice recordings, and sound effects.

Common extensions: MP3, WAV, FLAC, OGG, AAC, M4A, OPUS

Advantages

+ FLAC and WAV preserve full quality for editing
+ MP3 and AAC are universally compatible
+ OPUS delivers great quality at low bitrates

Disadvantages

− Uncompressed WAV files are very large
− Lossy formats cannot be restored to original quality
− DRM-protected files may not convert

Frequently asked questions

Yes, because TIFF is a lossless raster format and HEIC uses lossy compression, some data is discarded. However, HEIC uses advanced compression algorithms to keep visual degradation to a bare minimum.

TIFF files store uncompressed or lightly compressed pixel data, resulting in massive file sizes. HEIC applies efficient modern compression designed to dramatically reduce file size while retaining acceptable image fidelity.

Most standard HEIC converters will extract only the first frame or primary image from a multi-page TIFF, as HEIC is primarily structured for single-image frames and live photos.
