Is this AVIF to TIFF converter really free?

Yes. Up to 5 files at a time, no signup, no catch. The free tier adds a small watermark to image output — Pro ($9.99/mo or $49/yr) removes it, raises the file size limit to 500 MB, and unlocks unlimited batch conversion.

Are my files uploaded to a server?

No — and you can verify it yourself. Open DevTools → Network tab, then convert a file. You'll see zero upload requests. Everything runs right in your browser. We never see your files.

How long does conversion take?

Usually 1–3 seconds for a typical file. The very first conversion on a fresh page load may take 5–20 seconds while the converter engine loads — after that it's instant. Your CPU does all the work locally.

What is the file size limit?

Free: up to 10 MB per file, 5 files per batch. Pro: up to 500 MB per file, unlimited batch. If you're working with large videos or RAW photos, Pro is built for that.

Can I batch convert multiple AVIF files at once?

Yes — drop multiple files at once (or Ctrl/Cmd+click to select them) and they all convert in parallel. Free accounts handle up to 5 files per batch; Pro has no limit.

Will the image quality change after conversion?

It depends on the formats involved. Converting to a lossless format like PNG preserves every pixel exactly. Converting to a lossy format like JPEG or WebP applies compression — we default to 85% quality, which looks identical to the original for almost all images. You won't notice a difference unless you zoom in pixel-by-pixel.

Do you support batch image conversion?

Yes — drop multiple images at once and they all convert in parallel. Free accounts handle up to 5 at a time; Pro is unlimited. Download everything as a single ZIP when you're done.

Why convert an AVIF to TIFF for printing?

Print RIP software and professional print labs typically require TIFF. AVIF is optimised for web delivery and is rarely accepted as a print source format. Converting to TIFF makes the file compatible with every professional print workflow.

Will print quality suffer if I convert from AVIF to TIFF?

Quality depends on the AVIF's resolution and the quality setting it was encoded at. If the AVIF was encoded at high quality and sufficient resolution (300 DPI at print size), the TIFF output will print well.

How private is this converter?

Completely private — by design, not policy. There is no upload endpoint. Files are processed right inside your browser tab and disappear the moment you close it. We collect only anonymous page-view counts; your file content is never seen or stored.

AVIF vs TIFF: format overview

AVIF

TIFF magic bytes: 49 49 2A 00 (little-endian) / 4D 4D 00 2A (big-endian)

Why convert AVIF to TIFF?

AVIF is built for the web — efficient compression, small files, fast loading. TIFF is built for professional workflows — lossless quality, rich metadata, compatibility with print and archival systems. When an AVIF image needs to enter a print production pipeline or a scientific imaging system, TIFF is typically the required input format.

Adobe Photoshop and Lightroom handle AVIF as of recent versions, but downstream tools in a print workflow — RIP software, color management systems, InDesign placed-image validation — often only accept TIFF. Medical imaging databases, geospatial platforms, and museum digital archives specify TIFF for ingest. Converting AVIF to TIFF bridges the gap between a modern web-optimized source and a professional-grade delivery format.

Because AVIF uses lossy compression by default, the TIFF output is a lossless encoding of the already-decoded AVIF pixels — it doesn't recover detail that AVIF's codec discarded. The result will be significantly larger than the source AVIF: a 500 KB AVIF might become a 15–30 MB TIFF. That's expected. If the AVIF source was encoded at high quality, the TIFF will look excellent. If it was heavily compressed to save bandwidth, the TIFF will faithfully preserve whatever detail survived.

Quality & file size: AVIF to TIFF

Typical file sizes: AVIF 0.8–2 MB → TIFF 20–70 MB.

Converting from lossy AVIF to lossless TIFF will not recover detail the AVIF codec already discarded — but the output will not degrade any further. This is useful when you need a lossless format for editing or compatibility without additional compression artifacts.

Color depth: AVIF supports 12-bit, TIFF supports 32-bit.

Transparency: AVIF supports transparency. TIFF preserves transparency.

Privacy: how FormatDrop handles your files

Your AVIFfiles are converted 100% inside your browser. They are never uploaded to our servers, never stored, and never seen by anyone other than you. This isn't a privacy policy claim — it's an architectural guarantee: our server has no endpoint that receives file bytes.
