What does the MP4 to BMP converter do?
+
It converts a MP4 file into BMP format.
Will background and colour fidelity be preserved?
+
Neither MP4 nor BMP carries an alpha channel, so the background renders as a solid colour and pixel colour data is preserved end-to-end.
Is the MP4 to BMP conversion reversible?
+
You can convert the BMP back to MP4 on this site. If either format involved is lossy, the round-trip is not bit-perfect even though it is visually or audibly close.
Will the BMP be larger than the MP4?
+
Yes — lossless containers store every byte. Expect the BMP to be 3-8x the size of the MP4. The benefit is no further quality loss on editing or re-encoding.
Is there a file-size limit when converting MP4 to BMP?
+
Anonymous uploads are capped at a generous default; signed-in free accounts get a higher cap, and Pro accounts have no per-file limit. Browser memory is usually the practical constraint long before our server-side limits kick in.
Can I batch-convert several MP4 files to BMP at once?
+
Yes. Drop or pick multiple MP4 files in one upload — the converter processes them in parallel and returns a ZIP of the BMP results. There is no need to repeat the upload step per file.
What happens to my MP4 files after the conversion?
+
Uploaded files and BMP outputs are auto-deleted after a short retention window. We do not inspect, share, or train on user files. Direct download links are time-limited and tied to your session.
Where can I open a BMP file?
+
BMP opens in mainstream image viewers and editors. For web embedding, consider converting to PNG or WebP first since BMP is not always natively supported in browsers.
Do I need to install software to convert MP4 to BMP?
+
No. The converter runs entirely in your browser plus our cloud — no plugin, no install, no admin rights. It works on Windows, macOS, Linux, ChromeOS, iOS, and Android.
Do I need an account to convert MP4 to BMP?
+
No. MP4 to BMP conversion is free and works without an account. Signing in unlocks higher file-size caps, batch history, and API access.
Is there an API for MP4 to BMP conversion?
+
Yes. Every conversion this site offers is also exposed via a JSON API — see /api/ for endpoints, authentication, and rate limits. MP4 to BMP is one of the supported pairs.
What if my MP4 fails to convert to BMP?
+
Failures are usually caused by corrupted source files or unsupported MP4 variants. Re-export from the original app and try again; if it still fails, the contact page forwards the file to support so we can diagnose.
