GIF size guide

Make a Smaller GIF That Still Looks Good

Three settings define file size: width, duration, and frame rate. Effects matter less than they seem.

Steps

01
Set the width first
Width has the biggest impact on file size. Before changing anything else, pick the smallest value that still looks good. 480 px works for most. 320 px for chat and mobile.
02
Cut to the exact moment
Trim to the exact moment that matters. A 2-second clip with clear action is always better than 5 seconds with pauses.
03
Choose size and FPS
Start with a practical width and frame rate, then preview the motion before exporting.
04
Export and check
If the file is over 5 MB, reduce the width before lowering FPS. Halving the width cuts size by ~75%. If the motion feels choppy, raise the FPS, not the width.

What actually drives file size

Factor	Impact	What to do
Width	Very high	Start at 480 px. Halving the width cuts size by ~75%.
Duration	High	Cut to the moment. Remove pauses and lead-in.
Frame rate	Medium	10–12 fps is enough for most motion.
Preset/color	Low	Color changes add almost no size.
Grain/Film Dust	Low	Subtle texture adds very little.
VHS effect	Medium	Lines and noise add some size.
Light Leak	Low–medium	Depends on intensity and style.

Pick the right size for your use case

Most reaction GIFs and short loops work well at 480 px and 12 fps. For chat and email, 320 px keeps files small. See the MP4 to GIF guide for use case recommendations.

Width is the biggest lever

Halving the width from 640 px to 320 px reduces file size by roughly 75%. That is more than any other setting. Start there before adjusting frame rate or cutting more duration.

When to use 10 fps vs 15 fps

12 fps works for most short GIFs, clips with slow or moderate motion, and anything where the loop is the point.

Use 15–20 fps for fast movement: sports, gaming, or scenes where smoothness is part of the result.

Use 10 fps when file size needs to stay small and the motion is simple.

Effects and file size

Presets change the colors and mood of your GIF. They don't add frames or make the file heavier. "Warm Cinema" and "Matte Fade" cost almost nothing in size.

Grain and Film Dust add light texture. At low intensity, the impact on file size is small.

VHS adds visible lines and noise. At high intensity, it can increase file size.

Light Leak at low intensity adds almost nothing. At high intensity it can add some size.

If file size is the priority, keep effects subtle. Most presets won't change the file size.

GIF Quality: High, Balanced, or Smaller file

The editor offers three quality presets.

High keeps every frame at the selected FPS. Best when motion smoothness matters.

Balanced is the default. It works for most cases.

Smaller file reduces the effective frame rate to keep the file lighter while preserving the full duration of your clip. The moment stays complete. Motion may feel slightly less smooth, but nothing gets cut.

GIF or MP4?

Use GIF for short loops, reactions, tutorials, and visual moments that need to play anywhere: in chat, on social media, and in emails.

Use MP4 when the clip is longer, has more motion, or needs a smaller file with smoother playback. MP4 export is available with a Pro plan.

What to check before exporting

01: Is the width at the smallest value that still looks good?
02: Does the clip start and end at the right moment, with no pause?
03: Is the FPS right for the speed of the motion?
04: Are effects at low or moderate intensity?

FAQ

Width is the biggest factor, followed by duration and frame rate. A 640 px GIF at 15 fps for 6 seconds will be much larger than the same clip at 480 px, 12 fps, 3 seconds.

For most reaction GIFs and simple motion, no. Fast movement, sports, or gaming benefit from 15 fps or higher.

Very little. Presets change the colors but do not add frames or extra detail that would make the file heavier.

It lowers the frame rate to keep the file small while preserving the full duration of your clip. Motion may feel slightly less smooth, but the moment stays complete.
