Speed Adjustment Flexibility
Choose 0.25×, 0.5×, 1×, 1.5×, or 2×, or switch to a custom 20–2000ms frame interval when uniform timing is required.
Choose a preset or exact frame interval, remove duplicate frames when useful, and preview the new loop before downloading.

Changes render automatically after you stop adjusting.
Upload a GIF to create the first preview.
Your GIF stays on this device. No upload, account, or credits.
Choose a speed preset or uniform frame interval, review the regenerated animation, and keep the source loop behavior in the downloaded GIF.
Choose 0.25×, 0.5×, 1×, 1.5×, or 2×, or switch to a custom 20–2000ms frame interval when uniform timing is required.
The browser automatically regenerates a local preview after a short debounce, letting you inspect the changed motion before downloading.
FFmpeg WebAssembly retimes and exports the GIF on your device. The file is not sent to a server-side media-processing API.
The exported GIF carries forward infinite looping, finite repeat counts, or play-once behavior when the source loop metadata is available.
Optionally drop visually repeated frames before retiming. This can help screen recordings, but intentional held frames should be reviewed in the preview.
Set one frame interval from 20ms to 2000ms to normalize uneven timing for a specific playback rhythm or platform requirement.
Step 1
Upload an animated GIF up to 50MB or use the real sample.
Step 2
Choose 0.25×–2× or enter an exact frame interval.
Step 3
Review the regenerated loop, then save the GIF.
Choose 1.5× for a moderate speed increase or 2× for a shorter, faster loop. The editor reduces the frame timing, regenerates the animation locally, and preserves its loop setting.
Best first check: confirm expressions remain readable at 1.5× before moving to 2×.
Choose 0.5× for half speed or 0.25× for quarter speed. A custom frame interval gives exact control when you need every frame to remain visible for a defined number of milliseconds.
Best first check: watch for intentional held frames before enabling duplicate removal.
Presets cover common edits. Custom frame interval gives precise control when a platform or production workflow needs a specific delay.
The exported GIF retains the source loop behavior, including infinite loops.
Intervals below 20ms are avoided because browsers commonly clamp extremely short frame delays.
FFmpeg.wasm runs on this device. The GIF is never uploaded to a conversion server.
Screen recordings and repeatedly edited GIFs can contain frames that look identical. Removing those frames can reduce waste before timing is applied.
Use it when motion pauses unexpectedly even though the timeline continues.
Leave it off when tiny changes, flicker, or held frames are intentional.
Review the live result before downloading; deduplication changes the frame sequence.
A changed GIF can still look wrong when the source contains duplicate frames, extreme delays, or too much detail for fast browser encoding.
The source already uses very short delays
Use duplicate removal or a less extreme source; browsers may clamp delays below 20ms.
One or more frames have a long hold
Enter a custom interval to normalize timing, then compare with the original.
Similar frames were intentional
Turn duplicate removal off and change only the speed preset.
The GIF is large or has many decoded pixels
Compress or resize the GIF, then run the speed change again.
Browser-local processing
Your GIF is processed on your device. Nothing is stored on our media servers, and you can leave the page when the download is complete.
It tightens many reaction GIFs without making expressions hard to read.
Half speed makes gestures and frame transitions easier to inspect.
Small intentional changes can look like duplicates at a glance.
Browsers commonly clamp ultra-short delays, so frame dropping may work better.
Choose an animated GIF up to 50MB, then select 1.5× or 2×. The browser regenerates the preview locally after the change. Review the motion and download the faster GIF when it looks right.
Yes. Choose 0.5× for half speed or 0.25× for quarter speed. For uniform timing, enter a custom frame interval between 20ms and 2000ms, then compare the regenerated preview before downloading.
A frame interval is the time each output frame remains visible. A larger millisecond value slows the animation, while a smaller value speeds it up. Custom timing normalizes frames to one interval rather than preserving every original delay.
The source may already use extremely short frame delays, and browsers commonly clamp very fast timing. The editor therefore uses a practical 20ms minimum. Duplicate removal can help when repeated frames consume time without visible movement.
No. The exporter carries the source loop behavior into the regenerated GIF, including infinite looping, finite repeat counts, and play-once behavior when that metadata is available.
No. Preview and export run locally with FFmpeg WebAssembly in your browser. The GIF is not sent to a server-side media-processing API, and no account is required for the local workflow.
The optional FFmpeg duplicate-removal filter drops frames it detects as visually repeated before new timing is applied. It can reduce waste in screen recordings, but it may remove intentional held or subtly changing frames, so compare the preview carefully.
One or more source frames may have a long hold. Entering a custom interval can normalize the output timing. If motion starts jumping, turn duplicate removal off and change only the speed or interval.
Watch the locally regenerated preview before downloading. Check whether expressions remain readable, fast movement stays coherent, pauses occur where intended, and the beginning and end form the expected loop.
The tool accepts GIF files up to 50MB and applies browser-complexity limits, including a maximum of 1,000 frames. Compress, resize, or trim an oversized or highly complex GIF before changing its speed.
