Up to 100 MB free · 1 GB with Pro

HEIC, animated WebP input, PNG sequences and frame sequence export require Pro.

Google Ads turned down your animated banner: the file is over 150 KB, or the animation runs too fast or too long. Fixing that by hand means guessing at colors, frame rates and dithering until the file fits. Drop the GIF here instead — Google Ads is already chosen, so you press Convert and get back a GIF under 150 KB.

Your banner keeps its exact dimensions. LightBox slows the animation to the frame rate Google Ads accepts, keeps it within Google's length limit, then reduces the palette, the dithering and the frame rate step by step until the file is under 150 KB. If it still can't fit — a long animation or a very large banner — it stops and tells you, and a shorter clip or a smaller banner is the fix.

It does not resize. Start from a GIF or a video that is already at your banner size, and the output stays at that size. The Google Ads destination is part of Pro: unlock it with a one-time upgrade or a 24-hour pass. Nothing is ever watermarked.

Why convert with LightBox

Under 150 KB, fitted for you

LightBox works down a fixed list — fewer colors, lighter dithering, a lower frame rate — checks the size after each step, and stops at the first one under the cap.

Same banner, same dimensions

The output keeps the width and height of your file to the pixel, so it drops straight into the ad slot you designed it for. Nothing is squashed or stretched.

Within Google's motion rules

The animation is slowed to the frame rate Google Ads accepts and held within its length limit, so the file isn't turned away for animating too fast or too long.

Free forever. Pro when you need more.

Convert common formats free. Lifetime Pro adds more capacity and permanent hosting, with no subscription.

Frequently asked questions

Uploaded animated ads have to stay under 150 KB, run no longer than Google's length limit and animate below its frame-rate limit. A GIF exported from a design tool or made from a video often breaks at least one of those. LightBox converts it to meet all three, or tells you when it can't.

No. The GIF keeps its own width and height. Make or export it at the ad size you need first, then compress it here. A large banner has more pixels to fit into 150 KB, so it has less room for frames and colors.

LightBox stops and tells you rather than handing you a file Google would reject. Use Trim to shorten the animation, or start from a smaller banner, and convert again.

Yes. Drop an MP4, MOV or WebM that is already at your banner size and it becomes a GIF for Google Ads. Trim it to the seconds you want; the converter won't let the clip run past Google's length limit.

The Google Ads destination is part of Pro. Unlock it with a one-time Pro upgrade, or with a 24-hour pass if you have one campaign to ship. Making an ordinary GIF, without the Google Ads fitting, stays free.
