GIF stores palette-based still images or frame animations.
APNG stores full-color animation in a PNG-compatible chunk structure.
Every GIF frame is decoded and written as a full-color APNG frame with lossless image data.
APNG can preserve transparency and color detail, but the result can be larger than the source GIF.
Choose trim points, an optional source-pixel crop rectangle, even output dimensions, frame rate, rotation, and flip. APNG output has no audio stream.
One file is processed per request. The input limit is 100 MB.
The web application validates the file before forwarding it to a private worker. The worker validates the signature again, processes the file inside a unique temporary directory, validates the output, and removes the job directory in a guaranteed cleanup path. Files are not written to the database or retained for analytics.
When you import from a URL, the application fetches only a validated public HTTP or HTTPS address, checks the downloaded file in memory, and applies the same worker cleanup rules. The URL, filename, and file contents are not sent to analytics.
