How to use GIF Maker
- Choose the source file or ordered images.
- Review animation-specific controls.
- Preview and download the measured result.
GIF Maker
Create an animated GIF from ordered JPG, PNG, WebP, or AVIF frames without uploading them.
GIF Maker uses a separate frame-aware pipeline; it never sends an animated file through the static first-frame canvas path.
How OpenFileTools processes it
Local processing, explicit choices.
The browser lazy-loads GIF decoding and encoding code, composites disposal-aware frames, applies the operation to every frame, and creates an animated GIF locally.
Quick technical summary
What this tool changes.
| Property | Behavior |
|---|---|
| Processing | Browser only; no image upload |
| Original | Never changed |
| Timing | Global and per-frame delays |
| Loop | Forever or finite count |
Build an animation without distorting frames
Add ordered static images, set one delay for all or tune individual frames, then choose Fit, Fill/crop, or Contain/pad for mixed source sizes. Images are measured and decoded sequentially so a large selection does not create an unbounded bitmap spike.
- Fit preserves the whole frame with transparent unused canvas.
- Fill/crop fills the canvas and removes overflow.
- Contain/pad preserves the whole frame on the chosen background.
Questions, answered.
Can I reorder or remove frames?
Yes, before encoding.
Are mixed-size images stretched?
No. The selected sizing strategy controls fit, crop, or padding.
