Is this MP4 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 in your browser via WebAssembly. 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 WebAssembly codec 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 MP4 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 using WebAssembly 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 MP4 to GIF?

Video is great, but it's also heavy and requires a player. GIF is everywhere — it plays automatically in Slack, embeds in emails, loops in documentation, and requires zero interaction from the viewer.

If you've got a funny clip, a quick screen recording, a product feature demo, or a short reaction video, a GIF is often the right format for sharing it. It auto-plays, it loops, and it works everywhere without a "press play" button.

The trade-off: GIF doesn't support audio, and its 256-colour palette means it works best for short clips with limited colour variety. For longer videos or footage with lots of colour gradation, keep the MP4.

When to convert MP4 to GIF: - Sharing a clip to Slack, Teams, or Discord (GIFs play inline, videos need clicking) - Embedding a demo in a README, docs page, or presentation - Creating a looping reaction or meme from a short clip - Social media posts where auto-play GIFs get more engagement than linked videos

Quality & file size: MP4 to GIF

Typical file sizes: MP4 100–300 MB → GIF 1–5 MB.

Converting from lossy MP4 to lossless GIF will not recover detail the MP4 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: MP4 supports standard color, GIF supports 8-bit.

Transparency: MP4 does not support transparency. GIF preserves transparency.
