Is this AVI to GIF 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 AVI 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.

How large can my video files be?

Free accounts support files up to 10 MB — enough for short clips and GIFs. Pro raises that to 500 MB, which covers most 1080p videos. For files over 1 GB, a native app like HandBrake will be faster.

Will the video lose quality during conversion?

When only the container changes (e.g., MKV → MP4 where both use H.264), there's zero quality loss — it's a lossless rewrap. When the codec changes, we encode at CRF 23, which is near-transparent for most content.

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.

Why convert AVI to GIF?

If you've ever tried to open a AVI file and hit a wall — the app won't accept it, the website rejects it, or the preview just shows a broken icon — you already know why this conversion matters.

Audio Video Interleave is great for what it was designed for, but it has real-world limitations: large file sizes (minimal compression) and poor streaming support. The moment you step outside that original context, it gets frustrating fast.

Graphics Interchange Format is the safer choice for Memes and reactions, Simple web animations, Email marketing. Its main advantages — universal animation support in browsers and supported everywhere including email clients — mean it just works wherever you need it.

A few common reasons people end up here: - Their target app, site, or device doesn't accept AVI - They need a smaller file for email or upload (GIF often compresses better) - They need Graphics Interchange Format's specific capability: universal animation support in browsers - Compatibility with older software that pre-dates Audio Video Interleave

The conversion is one-way: you get a GIF that works everywhere Graphics Interchange Format is expected. The original AVI file is not touched.

Quality & file size: AVI to GIF

Typical file sizes: AVI 200–600 MB → GIF 1–5 MB.

Converting from lossy AVI to lossless GIF will not recover detail the AVI 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: AVI supports standard color, GIF supports 8-bit.

Transparency: AVI does not support transparency. GIF preserves transparency.
