FAQ
What image formats are extracted?
JPEG, PNG, and embedded bitmaps. Vector graphics are not extracted as they are rendered, not stored as images.

How large of a file can I convert?
Files up to 10MB work smoothly. Larger files may slow down depending on device memory.
Will data be lost during conversion?
No. MKV to MP4 remuxes video streams without re-encoding, quality unchanged.

No. All processing happens locally in your browser. Data never leaves your device.
