Is this WEBM 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 WEBM 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 WEBM to GIF?

WebM is a modern video format used extensively by browsers, particularly for HTML5 video elements, screen recordings exported from Chrome, and clips downloaded from web-based video editors. It offers excellent compression and is ideal for streaming, but it is not the format you reach for when you want to paste a reaction clip into a Slack channel, embed a looping animation in a GitHub README, or upload a meme to Reddit. Most chat platforms and forums expect GIF for short looping content.

GIF requires no video player, no codec, and no plugin. It renders inline in virtually every web context, from email clients like Gmail and Outlook to messaging apps like Telegram and WhatsApp Web. Adding an animated GIF to a GitHub issue, a Notion page, or a marketing email is a one-step drag-and-drop operation. For short clips under five seconds, GIF remains the most frictionless sharing format available.

Converting WebM to GIF involves breaking the video into individual frames and encoding them in the GIF container, which is limited to 256 colors per frame. The result will show some color reduction and dithering compared to the original WebM, especially in areas with complex gradients. Frame rate is often reduced to control file size, typically to 10 to 15 frames per second, which is sufficient for most animation purposes. The output file size grows quickly with clip duration, so keeping GIFs under five seconds produces the best balance of quality and shareability.

Quality & file size: WEBM to GIF

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

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

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

Your WEBM files are converted 100% inside your browser. They are never uploaded to our servers, never stored, and never seen by anyone other than you. This isn't a privacy policy claim — it's an architectural guarantee: our server has no endpoint that receives file bytes.
