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?

AVI files are a legacy Windows video format that has been around since the early 1990s. They appear frequently as output from older screen recording tools, vintage editing software, surveillance systems, and hardware encoders that have not been updated in years. While VLC can play AVI files, modern platforms like Slack, Discord, Google Chat, and most content management systems either reject AVI uploads outright or require additional codecs that users may not have installed.

GIF solves the sharing problem immediately. Short clips extracted from AVI files and converted to GIF can be pasted into chat threads, embedded in documentation sites like Confluence or Notion, used as tutorial animations on a help center, or included in email newsletters without any compatibility concerns. Tools like GIPHY and Tenor also accept GIF uploads, making it easy to build a shareable animation library from older video content.

The technical trade-offs of GIF are worth understanding before converting. AVI files often contain audio, which GIF cannot store, so sound will be lost in the conversion. Color depth drops to 256 colors per frame, which introduces visible banding in photographic video but is generally acceptable for screen recordings and simple animations. To keep file sizes reasonable, clip length should be kept short, ideally under eight seconds. Frame rate reduction to around 12 frames per second is standard and rarely noticeable in the output.

Quality & file size: AVI to GIF

Typical file sizes: AVI 200–600 MB → GIF 5–50 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.
