Video to GIF Without the 10 MB File: 10 Settings Measured on One Clip
A GIF stores every frame as a full picture, so a few seconds of video can easily turn into a 10 MB file that some platforms reject and pages load slowly. I took one 5-second clip, converted it with a free in-browser video to GIF converter (no upload, no sign-up, no watermark), and measured the GIF at ten combinations of length, frames per second and width. Here is what each setting actually…
A GIF's size is determined by its frame count and pixel dimensions. To reduce a GIF's file size, begin by trimming the clip to the necessary length, then adjust the frames per second (fps) and width. For instance, a 5-second clip at 8 fps and 360 px results in a 2.0 MB file. Cutting the clip to 2 seconds reduces the file size to 0.8 MB, while increasing the fps to 15 raises the file size to 3.1 MB.
The default settings, 8 fps at 360 px, produce a 1–3 MB file for a 5-second clip. To achieve a GIF under 2 MB, reduce any one of these settings, such as lowering the fps to 5, the width to 240 px, or trimming the clip to 3 seconds or less. For under 1 MB, limit the clip to 2–3 seconds or set the width to 240 px. The converter can produce up to 300 frames per GIF, enabling a 5-second clip at 15 fps and 640 px to be 9.6 MB in size.
However, the converter does not upscale the GIF width, which is limited by the video's original width. HEVC-encoded MOV files from recent iPhones can be converted into GIFs using Safari or Chrome/Edge on Mac and Windows, but may require adjusting phone settings to use the most compatible format.
