How to use Fit GIF in Rectangle
- 1. Upload the GIF. Drop in or browse for the animated GIF you want to fit into a box. Every frame is scaled together so proportions stay consistent throughout the animation.
- 2. Set the rectangle size. Enter Rectangle width and Rectangle height in pixels to define the target box. The GIF scales down or up to fit inside it while keeping its original aspect ratio intact.
- 3. Choose the fill color. Pick a Fill color for the space left over on either side of the scaled frame, since the GIF rarely matches the target box's exact proportions. Match a page background or use plain white.
- 4. Download the letterboxed GIF. Download the result once it renders. Every frame is now centered inside your chosen rectangle at a consistent size, padded with your fill color on the sides that do not fill.
When to use Fit GIF in Rectangle
Fit GIF in Rectangle scales an animated GIF to fit inside a fixed-size box without stretching or cropping it, padding any leftover space with a solid color. Use it whenever a layout needs a consistent slot size but the source GIF has an odd aspect ratio. The processing stays in your browser.
- Standardizing thumbnails in a gallery. A grid of animated thumbnails looks messy when each GIF has a different aspect ratio. Fitting them all into the same rectangle with matching padding keeps the grid visually aligned.
- Letterboxing a wide clip for a square slot. A wide GIF exported from a landscape video needs to sit in a square profile picture slot or product card. Fitting it in a square rectangle centers it with padding on the sides.
- Preparing an asset for a fixed ad unit. An ad placement requires assets at an exact pixel size regardless of source aspect ratio. Fitting the GIF into that rectangle ensures it meets the spec without distortion.
Examples
Letterbox a wide clip
Input
wide.gif → 500×500
Output
wide.gif scaled to fit, centered with padding
