Is this HEIC 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 HEIC 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.

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 HEIC to GIF?

If you've ever tried to open a HEIC 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.

High Efficiency Image Container is great for what it was designed for, but it has real-world limitations: poor browser support and requires codec on windows. 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 HEIC - 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 High Efficiency Image Container

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

Quality & file size: HEIC to GIF

Typical file sizes: HEIC 1.5–3 MB → GIF 1–5 MB.

Converting from lossy HEIC to lossless GIF will not recover detail the HEIC 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: HEIC supports 12-bit, GIF supports 8-bit.

Transparency: HEIC supports transparency. GIF preserves transparency.
