GIF Effects
Apply filters to animated GIFs, preview in real time before processing
GIF Effects Online - Add Filters to Animated GIFs Free
EzyIMG's GIF Effects tool applies visual filters to any animated GIF. You can see a live CSS preview of every effect before committing. Choose from Normal (no effect), Grayscale, Sepia, Invert, Blur, Sharpen, Brightness, Contrast, Saturation, Vintage, and Dark Mood. Each effect has an intensity slider (0-100%) so you can dial in exactly how strong the effect should be. Select multiple effects at once to combine them. It's ideal for fixing dark or washed-out GIFs, creating stylized animations, or adding a cinematic look to any looping clip.
All processing runs locally in your browser using WebAssembly, and your GIF is never sent to any server. No account is required and the output has no watermark. Effects are applied to every frame of the animation simultaneously using ffmpeg's filter chain, so the result is consistent across the full loop.
How to Use
- 1
Upload your GIF
Drag and drop an animated GIF file onto the upload area, or click to browse.

Click Apply and download
Click Apply. The selected effects are applied to every frame of the animation. Select Normal to download the original without any effect.
Key Features
- →The live preview you see while adjusting sliders is a CSS filter approximation; the actual export re-renders every frame through ffmpeg's equivalent filter, so double-check the final result before sharing.
- →Selecting Normal clears every other effect in one click and lets you download the untouched original.
- →Each effect's intensity slider runs from 0% (no change) to 100% (full strength), so you can land on a subtle version instead of an all-or-nothing look.
- →A dark or washed-out GIF often just needs a Brightness+ pass before anything else, try that alone before stacking more effects.
- →Sepia plus Dark Mood together produce a moodier, aged look than either effect gives on its own.
- →Multiple effects selected at once are combined into a single ffmpeg filter chain and rendered together, not as separate passes.
Frequently Asked Questions
Do I have to pay or register to use the filters?
No. Every filter, and stacking several together, is free with no account, no watermark, and no cap on file size.
Is my GIF sent to a server when a filter is applied?
No. The filter preview is pure CSS in your browser, and the final render runs through ffmpeg compiled to WebAssembly, so processing stays on your machine.
What can I upload, and what comes back out?
Upload an animated GIF and you get a filtered GIF back. Upload an MP4 or WebM instead and the filtered result is exported as MP4.
Can more than one filter be layered on the same clip?
Yes. Pick as many effects as you like; they're combined into a single filter chain and rendered in one pass, and the live preview shows roughly how the stack will look.
What exactly does dragging the intensity slider change?
It scales how strong that specific effect is, from 0% (no visible change) up to 100% (full strength), so you can dial in something between subtle and dramatic.
