GIF Merger

Combine multiple animated GIFs into a single file. Play them in sequence with crossfade or wipe transitions, overlay with per-layer opacity, place them side by side, stack them, or build a grid. Trim each GIF's frames, drop in a PNG or JPG as a static layer, and preview the result live before you export. Perfect for creating custom animations, adding a logo watermark, or combining reaction GIFs. New GIF? Try Video to GIF or the GIF Maker first.

How to Merge GIF Files

  1. Upload your files by dragging and dropping or clicking the upload area. You can add 2-10 files - animated GIFs plus optional PNG or JPG images as static layers. Need a GIF first? Make one with our GIF Maker or Video to GIF converter.
  2. Arrange the order by dragging the thumbnails. The sequence determines how GIFs appear in the final result.
  3. Trim each GIF with the start/end frame sliders on its card, so you only merge the frames you want - no need to open our GIF Cutter first.
  4. Choose a merge mode: Sequence (with optional crossfade or wipe transitions), Overlay (blend with opacity, position a logo or sticker), Side by Side, Stacked, or Grid layout.
  5. Preview live in the browser to check your layout before uploading, then adjust frame delay, size handling, and loop options.
  6. Merge and download your combined GIF. Afterwards you can compress it, resize it, or convert it to MP4.
Pro tip: For smoother animations, use GIFs with similar frame rates. You can adjust the speed of individual GIFs using our GIF Speed Changer before merging.

Merge Modes Explained

Sequence

Plays GIFs one after another to create a longer animation. Ideal for combining multiple reaction GIFs, creating storytelling sequences, or extending animation loops. Add a crossfade or wipe transition between clips for a polished, professional flow - something most free tools can't do.

Overlay

Composites GIFs on top of each other with full opacity control per layer. Set a layer semi-transparent for blending, ghost effects, or double exposures - or scale a top layer down and drop it into a corner to add a logo or sticker watermark. The first GIF is the base layer; all others blend over it.

Side by Side

Places GIFs horizontally next to each other, playing simultaneously. Perfect for before/after comparisons, reaction compilations, or displaying multiple perspectives of the same moment.

Stacked

Stacks GIFs vertically on top of each other, playing at the same time. Great for vertical comparison shots, timeline-style presentations, or social media content designed for mobile viewing.

Grid

Arranges GIFs in a grid pattern based on the number of files. All GIFs play simultaneously. Best for collages, multi-angle views, or showcasing several related animations together.

Popular Use Cases

Overlay Blending Effects

Composite two animations together with opacity control to create ghost effects, double exposures, or layered motion graphics.

Before/After Comparisons

Show transformations, edits, or changes side by side in a single animated image.

Animation Sequences

Chain together multiple short animations to tell a story or create longer continuous loops.

Frequently Asked Questions

In Overlay mode, GIFs are composited on top of each other frame by frame, all playing simultaneously. Each GIF has its own opacity slider (0-100%) on its file card. The first GIF is the base layer at full opacity. Set subsequent layers to lower opacity values to blend them into the base - for example, 50% opacity creates a classic double-exposure effect. This is the best mode for creating translucent overlays or blending two animations.

Yes! The tool automatically handles GIFs of different sizes. You can choose to match the largest, smallest, or first GIF's dimensions, or set a custom size. For best results, consider using our GIF Resizer to normalize sizes beforehand.

When merging GIFs with different speeds, you can either keep original timing or set a uniform frame delay. The "Original" preset preserves each GIF's native timing, while custom values apply the same delay to all frames. For synchronized playback in side-by-side and overlay modes, a uniform delay often looks better.

You can merge between 2 and 10 GIF files at once. Each file can be up to 10MB in size. If you need to combine more GIFs, you can merge them in batches and then merge the resulting files together.

The tool preserves the original quality of your GIFs as much as possible. However, if resizing is required some quality adjustment may occur. For the best results, start with source GIFs at your desired final resolution. You can also use our GIF Compressor afterward to optimize the file size.

If the output file is too large, you have several options: reduce the dimensions using our GIF Resizer, compress it with our GIF Compressor, or convert to a more efficient format like MP4.

Yes. In Sequence mode you can choose a crossfade or wipe transition, and set how many frames the transition spans for a smoother or snappier effect. Transitions are generated between each pair of clips, so a three-GIF sequence gets two transitions. If you only want to shorten a single clip instead, try our GIF Cutter.

Both are built in. Add PNG, JPG or WebP images alongside your GIFs and they act as static layers - perfect for a logo, frame, or background. Each GIF also has start and end frame sliders on its card so you can trim it before merging. To prepare images beforehand you can use our GIF Resizer or GIF Compressor. Still having trouble?
