How to Edit a GIF

Upload Your GIF

Drag and drop a GIF file onto the upload area, or click to browse and select a file from your device. The tool will automatically parse the GIF and extract all frames with their original timing information preserved.

Tip: The tool supports GIFs of any size, but larger files may take a few moments to process initially.

Edit Frames

Once loaded, all frames appear as thumbnails in the timeline strip below the canvas. You have complete control over individual frames:

Select a frame by clicking its thumbnail to preview it on the main canvas
Reorder frames by dragging thumbnails to new positions in the timeline
Edit frame delay by changing the millisecond value displayed below each thumbnail
Delete a frame by clicking the X button or using the Delete tool
Duplicate a frame using the Duplicate tool to insert a copy after the selected frame

Apply Transformations

Use the comprehensive toolbar to apply changes to the entire animation at once:

Speed

Multiply all frame delays by a factor ranging from 0.25x (slower) to 4x (faster)

Trim

Keep only frames within a specified range, removing unwanted content

Resize

Change output dimensions with optional aspect ratio lock to prevent distortion

Rotate / Flip

Rotate by 90°, -90°, or 180°, or flip horizontally/vertically

Reverse

Reverse the order of all frames to create backward playback

Preview

Use the intuitive play/pause controls to preview your edited animation in real-time. Step through frames one by one to verify timing and content accuracy. The frame indicator always shows your current position in the timeline.

Pro tip: The canvas displays a checkerboard background pattern to help you visualize transparent areas in your GIF.

Export

Choose your preferred export option based on your needs:

Export GIF — Render and download the edited animation as a new optimized GIF file
Save Frame — Download the currently selected frame as a high-quality PNG image
All Frames (ZIP) — Download every frame as individual PNG files packaged in a convenient ZIP archive

Features

GIF Parsing with Frame Extraction

Upload any animated GIF and the tool intelligently extracts all frames with proper compositing and transparency handling. Each frame's original delay timing is preserved and displayed, allowing you to adjust individual frame durations with millisecond precision.

Original

Uploaded GIF

All frames intact
Original timing preserved
Transparency maintained
Metadata extracted

Extracted

Frame Timeline

Individual frame thumbnails
Editable delay values
Drag-and-drop reordering
Frame-by-frame control

Frame Timeline

All frames are displayed as clear thumbnails in a scrollable timeline strip at the bottom of the editor. Click any thumbnail to select and preview it on the main canvas, drag thumbnails to reorder frames, and edit delay values directly beneath each frame. Frame numbers and the total frame count are always visible for easy navigation.

Speed Adjustment

Change the animation speed effortlessly with a simple multiplier slider ranging from 0.25x (4 times slower) to 4x (4 times faster). The multiplier is applied uniformly to all frame delays at once, maintaining relative timing between frames while adjusting overall playback speed.

Technical note: The tool enforces a minimum delay of 20ms per frame to ensure smooth playback across all browsers and prevent rendering issues.

Frame Trimming

Remove unwanted frames from the beginning or end of your GIF by specifying a precise frame range. Simply enter the first and last frame numbers you want to keep, and all frames outside that range are instantly removed. The trimmed animation updates immediately in the timeline with only the remaining frames visible.

Resize with Aspect Ratio Lock

Change the output dimensions of your GIF to meet specific platform requirements or file size constraints. Enable the lock option to automatically maintain the original aspect ratio when adjusting width or height, preventing unwanted distortion. You can reset to original dimensions at any time with a single click.

Rotate and Flip

Transform the entire animation by rotating all frames by 90°, -90°, or 180° degrees. Flip all frames horizontally or vertically to correct orientation or create mirror effects. All frame thumbnails in the timeline update instantly to reflect the applied transformation.

Frame Management

Delete unwanted frames individually to remove unnecessary content or duplicate specific frames to extend certain parts of the animation. Reverse the entire frame order with one click to create backward playback or boomerang effects. All changes are reflected immediately in the timeline and preview.

Live Preview

Preview your edited animation with professional play, pause, and frame-by-frame step controls. The main canvas shows a checkerboard background pattern for clear transparency visibility, helping you identify and verify transparent areas in your animation.

Multiple Export Options

Export your work in three flexible formats to suit different needs:

GIF Export

Renders a new animated GIF with all your edits applied. Real-time progress bar tracks encoding status.

Single Frame PNG

Saves the currently selected frame as a high-quality PNG image with transparency preserved.

All Frames ZIP

Packages every frame as individual PNG files in a downloadable ZIP archive for batch processing.

Your Data Stays Private

All processing happens entirely in your browser using client-side JavaScript. Your privacy and security are guaranteed:

No uploads — Your GIF file never leaves your device or gets transmitted over the internet
No tracking — We don't collect usage data, analytics, or any personal information
No server — Parsing, editing, and encoding all run locally using Web Workers for optimal performance

100% Private: This tool works completely offline after the initial page load. You can even disconnect from the internet and continue editing your GIFs.

Frequently Asked Questions

What file formats can I upload?

This tool accepts animated GIF files only. The GIF format must contain multiple frames to enable editing functionality. If you need to create a GIF from static images (PNG, JPG, etc.), use the GIF Maker tool instead, which allows you to combine multiple images into an animated GIF.

How does the Speed tool work?

The Speed tool multiplies all frame delays by a specified factor. Setting it to 2x halves all delays (making the animation twice as fast), while 0.5x doubles all delays (making it twice as slow).

Important: The minimum delay is always enforced at 20ms per frame to ensure smooth playback and prevent browser rendering issues.

What does Trim do?

Trim lets you keep only a specific range of frames from your animation. Specify the first and last frame numbers you want to preserve, and all frames outside that range are permanently removed from the timeline.

This is particularly useful for:

Cutting out unwanted intro or outro frames
Extracting a specific segment from a longer animation
Removing duplicate or unnecessary frames at the edges

Can I resize a GIF?

Yes, absolutely. Use the Resize tool to set custom width and height dimensions. Enable the Lock option to automatically maintain the original aspect ratio and prevent distortion.

The resize transformation is applied during the export process — your original frame data remains preserved in the editor, allowing you to adjust dimensions multiple times without quality loss until you're satisfied with the result.

How do I extract frames from a GIF?

You have two convenient options for frame extraction:

Save Frame — Click this button to download the currently selected frame as a high-quality PNG image with transparency preserved
All Frames (ZIP) — Click this button to download every frame as individual PNG files, all packaged together in a convenient ZIP archive for batch processing

Both export options maintain full image quality and transparency information from the original GIF.

Why does GIF export take a while?

GIF encoding is computationally intensive, especially with animations containing many frames or large dimensions. The process involves:

Color quantization (reducing colors to 256 palette)
Frame compositing and optimization
Compression and encoding

Performance optimization: The tool uses Web Workers for non-blocking rendering, keeping the interface responsive. A real-time progress bar tracks the encoding process so you know exactly how long to wait.

Can I undo my changes?

There is currently no undo button in the editor. However, you have several options to revert changes:

Reload original — Click the New button and select the same file again to start fresh
Reset dimensions — Use the Reset button in the Resize tool to restore original width and height
Work incrementally — Export intermediate versions as you work to create manual save points

Tip: Consider exporting a backup copy before making major changes like trimming or deleting multiple frames.

Is my GIF file uploaded to a server?

No, absolutely not. All GIF parsing, frame editing, transformation, and encoding happens entirely in your browser using client-side JavaScript and Web Workers.

Your file never leaves your device — there are no server uploads, no data transmission, and no cloud processing. This ensures complete privacy and security for your content.
