GIF Merger

Combine multiple animated GIFs into a single file. Merge GIFs side by side, stack them vertically, or sequence them one after another. Perfect for creating custom animations, combining reaction GIFs, or building longer sequences from shorter clips.

How to Merge GIF Files

  1. Upload your GIF files by dragging and dropping or clicking the upload area. You can add 2-10 animated or static GIFs.
  2. Arrange the order by dragging the thumbnails. The sequence determines how GIFs appear in the final result.
  3. Choose a merge mode: Sequence (play one after another), Side by Side, Stacked, or Grid layout.
  4. Adjust settings: Set frame delay, size handling, and loop options to customize your output.
  5. Merge and download: Click the merge button and download your combined GIF.
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. Each GIF plays completely before the next one starts.

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

Reaction GIF Combos

Combine multiple reaction GIFs into one expressive animation for social media and messaging apps.

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

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 horizontal and vertical modes, GIFs are scaled proportionally. 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 modes, using 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.

Absolutely! Static GIF images work just like single-frame animations. In sequence mode, they'll display for the set frame delay duration. In side-by-side and grid modes, they'll appear alongside animated GIFs as still images.

The tool preserves the original quality of your GIFs as much as possible. However, if resizing is required (for different-sized GIFs), 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 for your needs, you have several options: reduce the dimensions using our GIF Resizer, compress it with our GIF Compressor, reduce colors, or convert to a more efficient format like WebP or MP4.
