Does converting BMP to TIFF improve the image quality?

No. BMP and TIFF both store every pixel exactly, so the picture is untouched — only the file format changes.

What happens to transparency?

There is nothing to preserve: BMP has no transparency, so this does not come up.

Is there a file size limit?

No limit that we impose. The only ceiling is your device's memory, so a very large photo or a long recording may take a few seconds.

Are my files uploaded anywhere?

No. The conversion runs inside this browser tab, so the file never leaves your device — go offline once the page has loaded and keep converting.
