Questions

Are my BMP files uploaded?
No. File contents are processed in your browser on your device, rather than uploaded to ReFormatic.
Will converting BMP to PNG reduce quality?
PNG can avoid further lossy compression, but it cannot restore detail already lost in the BMP source. Resizing, palette conversion, flattening or unsupported features can still change the result.
Can I convert many files at once?
You can add up to 500 files to a batch, set a common format or adjust files individually, then download multiple results as a ZIP. Large batches may be limited by your device’s available memory.
