How to edit a GIF after it is created

Quick answer

To edit a GIF, open it in an editor that keeps every frame, such as GifRush’s GIF tools, then make one change at a time: trim frames, change the speed, crop, resize, add text or compress. Download the result as a new GIF. Ordinary photo editors often keep only the first frame, which stops the animation.

Grid of eight edits and the GifRush tool for each: length with GIF Trimmer, speed with Speed Changer, framing with Crop GIF, size with Resize GIF, words with Add Text, direction with Reverse GIF, looping with GIF Looper and file size with Compressor.
Find the change you want, and the tool that makes it.

Key takeaways

  • Use an editor that works on every frame. Many photo editors flatten a GIF to one image.
  • Every common edit has a tool: trim, speed, crop, resize, text, reverse, loop and compress.
  • Edit in order: cut first, polish last, and compress only at the very end.
  • Keep your original file so you can go back if an edit doesn’t work out.

Can you edit a GIF after it’s made?

Yes. A GIF is a stack of frames, each with its own timing, so almost anything about it can be changed: how long it is, how fast it plays, how it’s framed, what it says and how big the file is. What you can’t do is recover detail or colours that were lost when the GIF was first made. For that, go back to the original video and make the GIF again.

How to trim a GIF or change its speed

  1. Open the GIF Trimmer

    Drop your GIF into the GIF Trimmer. It shows the first and last frame you’re keeping.

  2. Choose the frames to keep

    Move the Start and End sliders. The new duration updates as you go, and frame timing inside the range doesn’t change.

  3. Trim and download

    Press Trim GIF and download the shorter version.

  4. Adjust the speed if needed

    Open the result in the GIF Speed Changer and choose a speed from 0.25× to 4×, or a fixed delay per frame.

In what order should you edit a GIF?

Each time a GIF is saved, its colours are worked out again. Doing edits in a sensible order keeps that from adding up, and also makes each step faster:

Five steps in order: trim, so later steps are faster; crop and resize, to set the final framing; speed, reverse and loop, which don’t touch the pixels; add text, so captions stay crisp at final size; and compress last.
Cut first, polish last.

Compressing is always last, because any later edit would rebuild the colours and undo some of the saving. If you need to hit a specific size, see how to make a GIF under 10 MB.

Frequently asked questions

How do I edit a GIF?

Open it in an editor that handles every frame, such as GifRush’s GIF tools, and make one change at a time: trim, change the speed, crop, resize, add text or compress. Then download the new GIF.

Why does my GIF stop moving after editing?

Many photo editors open only the first frame of a GIF, so saving produces a still image. Use a GIF editor that applies changes to every frame.

Can I edit a GIF on my phone?

Yes. GifRush’s tools run in a phone browser, and your GIF is processed on the phone without being uploaded.

Does editing a GIF reduce its quality?

Each save rebuilds the colour palettes, so many repeated edits can add up. Trim first, compress last and keep your original file.

Can I change the speed of a GIF?

Yes. A speed changer rewrites each frame’s delay. GifRush’s GIF Speed Changer goes from a quarter speed to four times faster.
