Why Choose Our APNG Speed Changer?
The most efficient way to adjust APNG animation speed directly in your browser.
No Re-encoding
We modify the frame delays directly in the APNG binary data. This means zero quality loss and instant processing, unlike tools that re-encode the image.
Secure & Local
Your files never leave your device. All speed adjustments happen locally in your browser, ensuring maximum privacy and security.
Batch Processing
Upload multiple APNG files and adjust their speed simultaneously. Save time by applying the same speed factor to your entire collection.

Use the slider to speed up (e.g., 2.0x) or slow down (e.g., 0.5x) the animation. Preview the changes instantly.
