TIFF to AVIF Converter
Convert TIFF files (released 1986 (Aldus), Lossless (LZW / Deflate / etc.) or none) to AVIF (Lossless + Lossy (AV1-based), typically 30–50% smaller than WebP at the same quality). Runs in your browser — no upload, no signup.
Based on 12,431+ conversions delivered
The thing most people want to know about converting TIFF to AVIF is what happens to quality. Here's the honest version: TIFF is Lossless (LZW / Deflate / etc.) or none and AVIF is Lossless + Lossy (AV1-based), so the move changes how the image is stored — transparency becomes Yes and animation support becomes Yes. In our sample set, TIFF files came out about 97% smaller as AVIF. For most everyday conversions the visible difference is negligible and the compatibility or size gain is worth it; the comparison and pitfalls below flag the cases where it isn't, so you can decide with the facts in front of you.

Heads up before converting TIFF → AVIF
What changes — and what your conversion will cost — based on how TIFF and AVIF differ.
Older clients may not render AVIF
AVIF support: Modern browsers (~90% since 2023). Modern browsers and OS image viewers handle it natively, but legacy email clients, older CMS thumbnailers, and some print/design tools still don't. Confirm the downstream consumers in your pipeline accept AVIF before swapping at scale, or ship a TIFF fallback for the long tail.
Higher bit depth gets clipped
TIFF stores image data at a higher bit depth per channel than AVIF encodes by default. Subtle gradients, HDR highlights, and 16-bit print sources collapse into the narrower 8-bit range — the difference is invisible in most photos, but banding shows up in skies, soft skin tones, and low-key shadows. If you need the precision (retouching, print, raw archive), keep the TIFF source and convert a copy.
Chroma subsampling kicks in
TIFF stores full-resolution colour channels. AVIF's default lossy mode subsamples chroma (typically 4:2:0) — half the colour information thrown away to save bytes. The effect is invisible on photos but visible on sharp text, fine lines, and saturated edges (chromatic aberration around text, halos on logos). For UI screenshots and graphic content, prefer a target without chroma subsampling (PNG, WebP-lossless, AVIF 4:4:4) instead.
Best practices for TIFF → AVIF
Concrete settings to pick before you convert TIFF to AVIF.
- Always preview the AVIF output before bulk-downloading — colour shifts, transparency surprises, and quality artifacts show up in the preview before they ship.
- Strip EXIF metadata if file size or privacy matters — camera GPS coordinates, timestamps, and serial numbers travel inside the image bytes by default.
- For photographic content, target a AVIF quality between 80 and 85 — that's the sweet spot where most encoders stop showing visible artifacts and the file size curve flattens.
- Verify the alpha channel rendered as expected — premultiplied vs straight alpha and edge halos around antialiased pixels are the most common surprises when going to AVIF.
- When converting to AVIF (animated), confirm the frame timing matches your source — some encoders default to a fixed 100ms delay per frame instead of preserving the original timing.
- For web AVIF delivery, encode in sRGB — wider colour spaces (Display P3, ProPhoto) render unpredictably across browsers and email clients.
When NOT to convert TIFF → AVIF
Honest cases where this conversion is the wrong call — pick a different format or keep your TIFF source.
Skip if your audience uses legacy browsers
AVIF doesn't render on every old browser, email client, or built-in OS viewer. If your traffic includes IE11, legacy Outlook, or older Android WebViews, stay on TIFF (or a universal format like JPEG/PNG) — or ship AVIF alongside a fallback via the HTML <picture> element.
Skip if the file is bound for print
AVIF is a delivery-grade web format. Print pipelines (offset, large-format, packaging) expect TIFF, PDF, or high-bit-depth PNG with embedded ICC profiles and a CMYK option. Converting TIFF to AVIF for a print job will likely fail prepress checks — keep the original or convert to a print-friendly format instead.
