Adjust brightness, contrast, saturation, and grayscale consistently across every complete animated WebP frame. Canvas applies one bounded filter chain to each decoded frame while retaining frame order, stored delays, canvas size, and loop count. The workflow checks actual file signatures and animation structure instead of trusting an extension, runs entirely in the browser, and leaves the selected source unchanged.
How to use Animation Editor
- Choose the required source file or ordered files and configure the visual adjustment controls.
- Run the local processor, then inspect the reported frames, timing, canvas, changed fields, and warnings.
- Download the derivative or report, test it in the intended destination, and keep the original until the result is approved.
What this tool is good at
When to use Animation Editor
Build a controlled visual animation adjustment
Apply the same restrained brightness, contrast, saturation, or grayscale correction to every displayed frame. Work from genuine animation structure and keep the selected source as the authoritative master until the complete output has been approved.
Troubleshoot composition privately
A single bounded Canvas filter chain keeps the sequence internally consistent and the result reports unchanged frame count, timing, and canvas dimensions. This supports client, product, research, and internal assets without transferring their image bytes to an unrelated processing service.
Document a repeatable handoff
Save the named derivative or JSON evidence with its reported timing, frames, dimensions, and warnings. This is not ICC-managed grading, selective retouching, HDR processing, or recovery of clipped detail, and re-encoding removes metadata.
How to choose the right settings
Change one dimension intentionally
Apply the same restrained brightness, contrast, saturation, or grayscale correction to every displayed frame. Use the focused controls to isolate the effect, then compare the first frame, intermediate composition, and final-to-first loop transition.
Respect browser memory
A small compressed file can decode into many complete RGBA canvases. Frame-count, pixel-frame, and output-size limits prevent an accidental animation from exhausting ordinary browser memory.
Verify the consuming application
This is not ICC-managed grading, selective retouching, HDR processing, or recovery of clipped detail, and re-encoding removes metadata. Test Chrome or the exact CMS, editor, messaging client, or runtime that will display or consume the result.
Practical workflow and output details
ImageDecoder resolves complete frames, Canvas adjusts RGBA pixels, and the existing WebAssembly muxer writes a fresh animated container. The source stays in the current browser tab; the application may load a local codec asset but creates no image-processing upload.
A single bounded Canvas filter chain keeps the sequence internally consistent and the result reports unchanged frame count, timing, and canvas dimensions. This is not ICC-managed grading, selective retouching, HDR processing, or recovery of clipped detail, and re-encoding removes metadata. The tool reports only the named operation and does not equate a structurally valid output with proven visual quality, accessibility, color accuracy, or universal playback.
Format behavior and limitations
Canvas applies one bounded filter chain to each decoded frame while retaining frame order, stored delays, canvas size, and loop count. Color adjustments are display-oriented transforms, not ICC-managed correction or restoration of clipped detail.
Complete displayed frames are decoded into RGBA canvases and remuxed as full-canvas keyframes. This makes the visual operation deterministic but strips EXIF, XMP, and ICC data and can change compressed size.

Frequently asked questions
Does the Animation Editor upload files?
No. Selected image bytes remain in the current browser tab; only application and codec assets are loaded.
Does this silently flatten animation?
No. The result is validated as a multi-frame animated WebP and retains explicit timing and loop behavior.
What should I verify?
Preview the complete result and compare frame order, timing, composition, transparency, and dimensions. Color adjustments are display-oriented transforms, not ICC-managed correction or restoration of clipped detail.
