How merging animated GIFs works
Merging GIFs is more than gluing files together: each input can have a different size, frame rate, and delay per frame. This tool normalizes every input to a common frame rate and a 480×480 canvas (scaled down and centered if needed), then concatenates them in sequence and rebuilds an optimized 256-color palette — the same two-pass technique our converter uses.
Everything happens locally with FFmpeg.wasm in your browser: no upload, no server, no watermark, no signup. Up to 5 GIFs, 100 MB each, free and unlimited.
Practical tips: merge plays files in the order listed above (use the ✕ to remove and re-add in the right order); if you need each clip trimmed first, trim it with the GIF trimmer before merging; and for posting on social platforms, converting the merged result to MP4 makes it 60–90% smaller.
What people merge GIFs for
Combine clips into one reaction
Two short reactions play stronger back to back. Select both files, keep the order you want (remove and re-add to reorder), and merge — the result loops as one GIF.
Build a step-by-step tutorial
Demo GIFs recorded one step at a time merge into a single walkthrough. Because every input is normalized to a common canvas and frame rate, mixed sizes and speeds still line up cleanly.
Merge, then compress
A merged GIF gets big fast — it carries every frame of every input. After merging, switch on the palette and frame-rate options (128 colors + 15 fps typically cuts 50–70%), or send the result through the GIF compressor. GIF compressor →
Frequently Asked Questions
How do I combine two GIFs into one?
⌄
Upload both files above with Merge switched on, click Merge, and download the single combined GIF. Free, no watermark, no signup.
Can I control the order of the merged GIFs?
⌄
Yes — clips play in the order shown in the file list. Remove a file with ✕ and re-add it to change the order.
What if my GIFs are different sizes or frame rates?
⌄
Every input is normalized first: scaled down to fit a common 480×480 canvas (centered, letterboxed) and re-timed to a common frame rate. Mixed inputs still merge cleanly.
Is there a limit on how many GIFs I can merge?
⌄
Up to 5 GIFs at once, 100 MB each — same as the batch converter. For longer sequences, merge in batches.
Is this GIF converter really free?
⌄
Yes — the browser converter is free with unlimited use, no watermark, and no account. It runs on your own device, so there is no server cost to pass on to you. AI enhancement (60fps, 2x upscale) uses paid GPU credits.
What is the best free GIF to video converter in 2026?
⌄
For free and private conversion, GIFtoVideoAI: unlimited use, files processed entirely in your browser (never uploaded), no watermark, no signup — plus optional AI 60fps and 2x upscaling. If you need heavier editing suites, ezgif offers more tools; we compare both honestly on this site.
Can I convert GIF to video on my phone without uploading?
⌄
Yes — the converter runs in mobile browsers (iOS Safari, Android Chrome). Processing happens on your device, so nothing is uploaded even on mobile. The result saves to Files (iOS) or Downloads (Android).
Are my files uploaded to a server?
⌄
No. Conversion runs entirely in your browser using WebAssembly (FFmpeg.wasm). Your GIF never leaves your device — you can even disconnect from the internet after the page loads and it still works.
