Frequently asked questions
Are files uploaded to your servers?
No. Conversions run in your browser using WebAssembly and Canvas. Files stay on your device.
What is the max file size?
On the free tier, up to 250MB per file, plus up to 20 completed conversions per day on this device (limits help keep the service sustainable). Large video encodes can take time — keep the tab open while processing.
When should I use WEBP?
WEBP is a common choice when you need compatibility or a specific workflow. This page is built for BMP → WEBP.
Does it work offline?
After the app loads once, many conversions can continue without network access (depends on the browser).
