Frequently Asked Questions

Does AVIF to TIFF lose quality?
The AV1 decompression is lossless — it exactly reconstructs what the encoder stored. But AVIF encoding is lossy by default, so detail was already discarded when the AVIF was created. The TIFF preserves exactly what remains with no additional quality loss.
Does AVIF to TIFF preserve 10-bit color?
Yes. 10-bit AVIF is decoded to 16-bit internally and written as a 16-bit TIFF, preserving the full color precision with additional headroom for editing.
How much larger is the TIFF compared to AVIF?
Typically 15–60× larger depending on resolution and bit depth. A 200 KB AVIF at 1080p becomes roughly 2.5–4 MB TIFF with LZW compression. This is the inherent cost of lossless storage.
What happens to HDR AVIF?
HDR transfer functions (PQ, HLG) are tone-mapped to SDR sRGB. The resulting 16-bit TIFF retains smooth gradients within the SDR range but loses extended dynamic range above SDR white.
Does AVIF transparency carry over to TIFF?
Yes. AVIF alpha channels are written as unassociated (straight) alpha in the TIFF output, compatible with Photoshop and professional editing tools.
Can Photoshop open AVIF directly?
Photoshop 26.8+ (June 2025) supports AVIF natively. For older versions, converting to TIFF or PNG is necessary.
Can I batch convert AVIF to TIFF?
Yes. Upload up to 10 AVIF files and download them all as TIFF simultaneously.
Is TIFF better than PNG for archiving decoded AVIF?
TIFF offers multi-page support, CMYK color space, and robust ICC profile handling that PNG lacks. For professional archival and prepress workflows, TIFF is standard. For web and design tool compatibility, PNG is more practical.

From web delivery to archival: what AVIF to TIFF does

AVIF uses the AV1 codec for maximum compression — files typically 50% smaller than JPEG at equivalent visual quality. But AVIF is a delivery format, not an editing or archival format. Most professional tools have limited AVIF support: Photoshop added native AVIF import only in version 26.8 (June 2025), Lightroom Classic support arrived in version 11.4, and many prepress workflows cannot ingest AVIF at all.

Converting to TIFF gives you a universally accepted professional format. The AV1 decompression itself is lossless — it faithfully reconstructs what the encoder stored. But AVIF is lossy by default, so some detail was already discarded during AVIF encoding. The TIFF preserves exactly what remains, losslessly, preventing any further quality degradation.

10-bit AVIF and HDR handling

AVIF supports 10-bit and 12-bit color depth with HDR transfer functions (PQ, HLG) and wide color gamuts (BT.2020). When a 10-bit AVIF is decoded, libvips stores the data in a 16-bit container (VIPS_FORMAT_USHORT). Writing this to a 16-bit TIFF preserves the full 10-bit precision with 6 bits of additional headroom — ideal for subsequent color grading.

For HDR AVIF, Convertify tone-maps PQ and HLG content to SDR sRGB before writing the TIFF, since TIFF has no widely supported HDR transfer function. The resulting 16-bit sRGB TIFF retains smooth gradients and wide tonal range within the SDR gamut — significantly better than an 8-bit conversion that would introduce banding in skies, skin tones, and shadow regions.

File size: the expected trade-off

AVIF is the most compressed still-image format in common use. A 200 KB AVIF photo at 1920×1080 becomes a 5.93 MB uncompressed TIFF (24-bit) or roughly 2.5–4 MB with LZW compression. At 4K resolution, expect 23.7 MB uncompressed or 10–18 MB with LZW. For 16-bit output, double those numbers.

This 15–60× size increase is the inherent cost of lossless storage. The AVIF achieved its tiny size by discarding perceptual detail through AV1 compression — TIFF stores everything that survived, uncompressed or with lossless compression only. If file size matters more than editing flexibility, keep the AVIF or convert to JPG or PNG instead.

AVIF transparency in TIFF

AVIF supports full 8-bit alpha channel transparency (and 10-bit alpha in some configurations). TIFF also supports alpha channels stored as extra samples. When converting an AVIF with transparency — common for product cutouts, UI assets, and design elements — the alpha data is preserved losslessly in the TIFF output.

Convertify writes TIFF alpha as unassociated (straight) alpha, which is the expected format for Photoshop, Affinity Photo, and most prepress software. If the source AVIF has no alpha (the typical case for photographs), the TIFF output is a standard RGB image.

When to convert AVIF to TIFF

The primary use cases mirror HEIF-to-TIFF: professional editing workflows where TIFF is the expected input, archival storage where TIFF's ISO standardization ensures long-term readability, print production where prepress RIPs and imposition software require TIFF, and any downstream system that has not yet added AVIF support.

If your goal is simply to open an AVIF file in Photoshop, check your version first — Photoshop 26.8+ handles AVIF natively, making the TIFF conversion unnecessary. For older Photoshop versions, AVIF to PNG may be simpler since PNG support is universal across all Photoshop versions.

How Convertify converts AVIF to TIFF

libvips loads the AVIF via vips_heifload() — the same loader handles AVIF, HEIC, and HEIF transparently since all are HEIF-conformant containers. The AV1 bitstream is decoded by libaom or dav1d (whichever is linked), producing a VipsImage at native bit depth. ICC profiles and EXIF metadata are read and attached.

For 10-bit sources, the VipsImage stores data in 16-bit USHORT format. vips_tiffsave() writes the output with LZW compression at the detected bit depth, preserving the ICC profile and any alpha channel. For HDR content, vips_icc_transform performs the BT.2020-to-sRGB conversion before encoding.

The entire pipeline streams pixels in tiles without materializing the full decoded image in RAM.
