TIFF to AVIF: what changes and when it makes sense

TIFF is a Tagged Image File Format. It is best known for archival quality, high bit depth and CMYK support. The main drawbacks are large files and no display support in most browsers.

AVIF is an AV1 Image File Format. It is best known for the smallest files of any common web format at a given quality. The main drawbacks are slow encoding, patchy support outside browsers, and smoothing in fine textures at aggressive settings.

TIFF vs AVIF at a glance

Property	TIFF	AVIF
Type	Container format	Raster image
Compression	Flexible: uncompressed, lossless (LZW or ZIP) or JPEG-compressed	Lossy or lossless, based on the AV1 video codec
Transparency	Full alpha channel with soft edges	Full alpha channel with soft edges
Animation	No	Yes
Colour depth	8, 16 or 32 bits per channel, with CMYK, layers and multiple pages	8, 10 or 12 bits per channel, with HDR and wide-gamut support
Support	Supported by professional editors, scanners and print workflows. Safari is the only major browser that displays it	Supported by current Chrome, Edge, Firefox and Safari, but many editors, social platforms and OS viewers cannot open it
History	Created by Aldus (later Adobe) in 1986 for desktop publishing and scanning. Owned by Adobe since 1994. Remains the professional standard for print, archival imaging and medical imaging.	Finalised in 2019 by the Alliance for Open Media (Google, Mozilla, Apple, Microsoft, Netflix, Amazon, Intel and others). Based on AV1 video codec, successor to VP9 and HEVC. First major browser support: Chrome 85 (2020).

What actually changes in this conversion

Moving from a lossless format to AVIF is where you trade fidelity for size. Start high and lower until the difference becomes visible.
Transparency is preserved, including soft edges.
Expect the AVIF file to be far smaller than the TIFF source.
Browser-based conversion works in 8-bit sRGB. Wide-gamut, 10-bit and 16-bit data are reduced. For colour-critical work, keep the original.
EXIF, GPS and camera data are stripped on every conversion. That is good for privacy, but you lose capture dates.

About TIFF: history and technical details

Created by Aldus (later Adobe) in 1986 for desktop publishing and scanning. Owned by Adobe since 1994. Remains the professional standard for print, archival imaging and medical imaging.

Technical: Tag-based file structure with IFD (Image File Directory) entries. Supports CMYK, Lab, RGB, grayscale, bilevel. 8, 16, 32-bit depth. Multiple pages. Layers via extensions. Compression: none, LZW, ZIP, JPEG, PackBits.

Real-world size: A 300 DPI A4 scan is 25-50 MB as uncompressed TIFF. Same as PNG: 10-20 MB. As JPG at quality 90: 3-8 MB but with loss. Print workflows use TIFF because quality is preserved and CMYK is supported.

Popular tools: Adobe Photoshop, Adobe Illustrator, GIMP, ImageMagick, Capture One, Vuescan, SilverFast.

Alternatives: PNG (8-bit only, no CMYK), JPEG XL (future format), PSD (Photoshop native), PDF (for sharing).

About AVIF: what you get

Finalised in 2019 by the Alliance for Open Media (Google, Mozilla, Apple, Microsoft, Netflix, Amazon, Intel and others). Based on AV1 video codec, successor to VP9 and HEVC. First major browser support: Chrome 85 (2020).

Technical: AV1 intra-frame coding with variable block sizes from 4x4 to 128x128. Supports 8/10/12-bit colour, HDR, wide gamut (BT.2020), monochrome. HEIF-based container. Encoding is 10-100x slower than JPEG.

Real-world size: AVIF at quality 50 produces files 30-50% smaller than JPG at quality 85 with similar visual quality. Netflix reports 50% bandwidth savings after switching. Google reports AVIF is 20-30% smaller than WebP.

Popular tools: Adobe Photoshop 2024+, GIMP 2.10+, Squoosh, avifenc, ImageMagick, AVIF.io, Netflix (production use).

Alternatives: WebP (faster encode, less compression), JPG (universal), HEIC (Apple-only), JPEG XL (future format).

Browser and software compatibility

TIFF: Supported by professional editors, scanners and print workflows. Safari is the only major browser that displays it. AVIF: Supported by current Chrome, Edge, Firefox and Safari, but many editors, social platforms and OS viewers cannot open it.

AVIF is well supported by current browsers but is still rejected by many editors and social platforms.

Why people move away from TIFF

Browsers other than Safari cannot display TIFF, so it is unusable on web pages.
TIFF files are huge. A single scan can run to hundreds of megabytes.
Email clients and chat apps often cannot preview TIFF at all.

Why people choose AVIF

AVIF often produces files 30 to 50 percent smaller than JPG at comparable quality.
It can carry 10-bit and HDR content that JPG and WebP cannot.
It pays off most on hero images and large photo galleries, where bytes matter the most.

Common mistakes with TIFF

Using TIFF for web images — browsers will not display it
Assuming all TIFFs are lossless — JPEG-compressed TIFF exists
Ignoring bit depth — a 16-bit TIFF converted to 8-bit loses tonal range

Best practices for keeping quality

TIFFs often hold 16-bit or CMYK data. Browser conversion works in 8-bit sRGB, so bit depth is reduced and colour can shift. For colour-critical work, use Photoshop or ImageMagick.
AVIF quality numbers do not line up with JPG. Start around 60-70 and compare against the original at 100 percent zoom.
Serve AVIF with a WebP or JPG fallback using the picture element so older browsers still get an image.
Resize before converting if the image will be shown small. A 4000 pixel photo displayed at 800 pixels wastes bytes in any format.
Check the result at 100 percent zoom, especially around text, edges and gradients, before you replace any originals.
Keep your original files. Conversions to a lossy format cannot be undone.
When you convert a set of images, use the same quality setting for the whole batch. The converter handles up to 20 files at once.

TIFF to AVIF questions

Quick answers about privacy, quality, supported formats, file limits and how AVIF works.

Why convert TIFF to AVIF?

AVIF files are typically smaller than TIFF, which makes them faster to share, send and load. The trade-off is a small amount of image detail at low quality settings.

Will converting TIFF to AVIF lose quality?

At 90% quality, most people cannot tell the difference. Use 85-95% for photos and you are fine.

Does AVIF keep transparency?

Yes. AVIF supports full transparency, so transparent areas in your original are kept.

Are my files uploaded?

Never. Everything runs in your browser. Your files never leave your device. Open DevTools Network tab while processing — you will see no upload request.

Can I convert many files at once?

Yes, up to 20 files at once. Download them individually or all together as a ZIP.

Does the converter strip metadata?

Yes. Browsers do not pass EXIF data through a canvas, so GPS, camera model and dates are removed on every conversion. That is good for privacy.

Is it free?

Yes. No credits, no daily cap, no account, no watermark. The practical limit is your device memory.

Is AVIF smaller than WebP?

Yes, typically 20-30% smaller at similar quality. But AVIF is much slower to encode and has less software support outside browsers.

Does AVIF support HDR?

Yes. AVIF supports 10-bit and 12-bit colour, HDR (Hybrid Log-Gamma and PQ), and wide-gamut BT.2020 colour. JPG and WebP cannot do this.

Can AVIF be animated?

Yes, though animated AVIF support is still limited in browsers. Chrome and Firefox support it, Safari does not as of early 2026.

Your files never leave your device

No upload, no account, no tracking. Everything happens in your browser using the Canvas API and WebAssembly. You can confirm this in your browser's DevTools Network tab while the tool runs — no request carries your file. See why ToolDeck is different.
