Does the free converter work for TIFF or BMP images?

Currently our MB to KB converter online free supports JPG, PNG, and WEBP. For TIFF or BMP files, convert them to JPG first using any free tool, then use ours to do the MB to KB convert.

How do I know the output will be accepted by the portal?

Our MB to KB converter always outputs a file at or below your target KB. If the portal says "maximum 50KB," set our target to 48KB. The output will be 45-48KB — guaranteed under the limit and always accepted.
