Helphonic

GIF Optimizer & Editor

Edit a GIF locally: reorder or remove frames, resize, change playback speed, reduce colors and preview the result.

Unlimited Free Usage

Choose a GIF to inspect its fully composed frames. Reorder or remove frames, resize the animation, change playback speed and reduce its colors. Transparency and frame disposal are composed before editing.

    Input: up to 10 MB, 1024 pixels per side, 120 frames, 120 seconds and 12 million combined frame pixels. Output may be larger than the source, especially after reordering. GIF timing is rounded to hundredths of a second, with a 20 ms minimum; colors and smooth transparency can change.

    Frequently asked questions

    Are my files uploaded?

    No. Source files, filenames, previews and output stay on your device. Helphonic serves the page and local processing libraries and checks access using non-content usage metadata.

    Is this tool free?

    This tool starts with unlimited free operations for guests, registered users and active paid users. Administrators can configure allowances later. Current access details appear on the page, and device safety limits still apply.

    Will this work on every browser?

    Use a current browser with JavaScript, canvas and worker support. HEIC conversion and GIF editing also need WebAssembly and enough memory for a local decoder. Video codec support varies by browser; smaller files work better on phones.

    What limits apply?

    Input: 10 MB, 1024 px per side, 120 frames, 120 seconds and 12 million combined pixels. Output: 800 px per side; 40 MB GIF cap.

    How to use

    GIF Optimizer & Editor

    Learn how to use GIF Optimizer & Editor: step-by-step instructions, settings, export options, privacy, limits and troubleshooting.

    Step-by-step instructions

    1. Choose a GIF and wait for its frames to be decoded locally.
    2. Use Up, Down, Remove or Reverse frames to arrange the animation.
    3. Choose maximum size, playback speed, palette colors and looping.
    4. Use Preview edited frames to check order and timing, then click Export edited GIF.
    5. Compare the original and result sizes, preview the encoded GIF and download it.
    Frame composition and editing

    GIF frame rectangles can depend on earlier frames. The tool composes transparency and disposal behavior into complete frames before displaying them, so removing or reordering a frame does not accidentally remove the image content needed by another frame.

    Restore original order brings back removed frames. The in-tool frame preview shows the edited order and timing; the generated GIF preview also shows palette reduction. Edits are temporary and are not saved after leaving the page.

    Optimization and appearance

    Smaller dimensions, fewer frames and fewer colors often reduce file size. Re-encoding is not guaranteed to produce a smaller file; some well-optimized originals or reordered frames become larger. The interface reports both sizes.

    GIF supports binary transparency and limited palettes. Smooth transparency and colors can change when resizing or quantizing. Playback speed scales frame delays, with a 20 ms minimum and 10-second maximum per frame; GIF delays are rounded to hundredths of a second.

    Safety and unsupported GIF features

    The GIF structure, dimensions and frame count are inspected before decoding. A self-hosted worker handles decoding with resource limits and a timeout. Cancel stops export encoding, and changing the file cancels its pending inspection.

    GIF text rendering blocks and invalid or unsupported disposal methods are rejected. Inputs above 120 frames, 120 seconds, 1024 pixels per side or 12 million combined canvas pixels must be reduced before use.

    Processing and privacy

    Files and entered content are processed on your device in this browser tab. File contents and results are not uploaded to Helphonic or sent to analytics. The page still contacts Helphonic to load its tools, check access and confirm non-content usage information. Work is not saved to your account; download or copy results before leaving or reloading the page.

    If an operation cannot finish

    Use a current browser and smaller inputs if the tab runs out of memory. Some tools download a local processing library or model on first use, so an internet connection is needed even though your content stays on the device.

    If the tool reports that access or limits changed, review the current policy and run it again. If usage confirmation is uncertain after an interrupted connection, a retry can count as another operation. Download completed work before reloading; this site does not keep a recovery copy.

    About this tool

    Choose an animated GIF, inspect fully composed frames and arrange them with Up, Down, Remove or Reverse. Adjust output size, speed, colors and looping, then preview and export the edited animation.
