Video to APNG Converter
Convert short video clips into lossless animated PNGs with full 24-bit color. Process files entirely in your browser without uploads or file size limits.
MP4, WebM, MOV, MKV, AVI, FLV, 3GP · up to 1 GB
Tips
- The processing engine downloads roughly 30 MB on your first visit and runs offline afterward.
- APNG uses lossless compression, making it ideal for short clips under five seconds to prevent massive file sizes.
- Downscaling video dimensions to moderate widths keeps memory usage stable and outputs manageable.
How to use it
- 1 Select or drop your video file into the converter area.
- 2 Start the conversion to let the browser engine decode frames into APNG format.
- 3 Download the resulting animated PNG directly to your device.
What you should know
While modern video containers like MP4 use temporal lossy compression to keep files compact, they frequently introduce visual artifacts, edge blurring, and chroma subsampling on crisp graphics. Animated PNG provides a lossless alternative that displays natively in standard image tags across all major web browsers without requiring embedded video players. Because APNG preserves pristine 24-bit true color across every sequential frame, it is the ideal format for high-fidelity interface previews, animated stickers, and technical documentation where pixel clarity matters. However, without inter-frame motion vectors, file sizes scale directly with resolution and duration.
This converter decodes your source video into individual graphic frames and re-encodes them directly into an animated PNG file. The entire conversion executes locally inside your browser tab using WebAssembly, ensuring complete data privacy without remote server uploads. Because APNG is an image format rather than a multimedia container, any embedded audio tracks are stripped automatically upon export. To keep output files manageable and prevent browser memory exhaustion, target short video sequences under five seconds and reduce pixel dimensions before exporting, as every frame adds uncompressed raster data to the final file.
Frequently asked questions
Why is the resulting APNG file larger than the original video?
Videos use advanced temporal inter-frame compression to discard imperceptible data, whereas APNG stores full raster frame sequences using lossless deflate compression. For animated graphics, this guarantees pristine visual quality but significantly increases file weight.
Is the audio from my video preserved in the APNG output?
No, APNG is an animated image standard that extends the PNG specification and does not support audio tracks. Any sound contained in your source video file is discarded during the conversion process.
Does the conversion process send my video to a remote server?
No, all decoding and APNG encoding happen locally inside your browser using WebAssembly. Your media files never leave your device, ensuring privacy and offline functionality after the initial engine load.
