Does converting JPG to BMP improve image quality?

No — detail the original JPG compression discarded is gone for good, and no format change can restore it. What BMP guarantees is that nothing further is lost: the decoded image is stored exactly, so it will survive repeated edits and saves untouched.

More systems than you might expect: legacy Windows applications, embedded devices, receipt and label printers, scientific imaging tools, and some game-modding pipelines. FileMorf writes plain uncompressed 24-bit BMP — the most universally readable variant of the format.

How large will the BMP file be?

Large. FileMorf writes standard uncompressed 24-bit BMP, which needs about 3 bytes per pixel regardless of content — a 4000x3000 image comes out around 34 MB. That is normal for BMP; only use it where a specific application requires the format.

Is my image uploaded to a server?

No. The entire JPG to BMP conversion happens locally in your browser using the Canvas API, so your files never leave your device. There is nothing to upload, no queue to wait in, and nothing for anyone else to store.

Questions about JPG and BMP.

Check the format behavior, limitations, and follow-up options before processing a real file.

Some Windows utilities, industrial software, and embedded systems read only BMP. The conversion decodes your JPG and stores the exact pixels uncompressed — no further quality loss — but expect a much larger file, since BMP applies no compression at all.
