Those old .bmp scans hogging your drive can shrink dramatically. Convert BMP to JPG free by dropping the files anywhere on this page: each one becomes a high-quality JPG that is usually 10-50× smaller and saves to your Downloads folder, and your images stay completely private. No upload, no file cap, no signup.
Digitizing the family archive?
BMPs usually come from old scanning software and 2000s-era Windows. For scanned photos, JPG at high quality is the right call. Batch a whole folder and flip Auto-download; every JPG saves itself the moment it's done.
FAQ
Why are BMPs so big?
Zero compression. Every pixel stored raw. A 10-megapixel scan is ~30 MB as BMP, ~2 MB as high-quality JPG, identical to the eye.
Are my scans uploaded?
Never. Your scans are never uploaded, stored, or seen by anyone. Family photos stay in the family.
