Is this GIF to AVIF 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 GIF 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.

Does GIF to AVIF work for animated GIFs?

This converter handles static images. An animated GIF will be converted using only its first frame. For animated content, use a video converter to export to AVIF sequence or WebM.

How much smaller will the AVIF be compared to the GIF?

For photographic content, AVIF is typically 50–70% smaller than GIF at similar quality. For flat-colour graphics, GIF's palette compression may be competitive, but AVIF will still usually win on file size.

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 GIF to AVIF?

GIF is one of the oldest image formats still in active use, and it shows. The 256-color limit produces visible banding on anything with gradients. The file sizes for animated GIFs are notoriously large — a 3-second looping animation can easily exceed 5 MB. Browsers support GIF for backward compatibility, but it's not a format that was designed for the web as it exists today.

AVIF supports full color, HDR, and animation (AVIF sequences), and achieves file sizes 50–80% smaller than equivalent GIF animations. For still images, converting a GIF to AVIF almost always produces a smaller file with noticeably better color fidelity. For animated content, the size reduction is even more dramatic. Platforms that serve image-heavy content — news sites, e-commerce, social media — have largely moved to AVIF or WebP for exactly this reason.

One compatibility note: AVIF animation is supported in Chrome and Firefox but not yet everywhere. If you're serving to a broad audience including Safari on older iOS or some mobile browsers, check your target browser support before replacing animated GIFs with AVIF sequences. For still images converted from GIF, AVIF support is near-universal in modern browsers. The color accuracy improvement alone — going from 256 colors to full 24-bit color — often makes a visible difference even on simple graphics.

Quality & file size: GIF to AVIF

Typical file sizes: GIF 1–5 MB → AVIF 0.8–2 MB.

Converting from lossless GIF to lossy AVIF will apply compression. We default to 85% quality — visually indistinguishable from the original for most content. If you need pixel-perfect output, consider using a lossless target format instead.

Color depth: GIF supports 8-bit, AVIF supports 12-bit.

Transparency: GIF supports transparency. AVIF preserves transparency.
