Submit files to /v1/convert, poll the job endpoint, then download outputs programmatically.
Converting BMP to PNG decodes the BMP input and writes a PNG output for compatibility, sharing, editing, or delivery. PNG can preserve decoded pixels losslessly when encoder settings are correct.
PNG is lossless for decoded pixels. File size depends heavily on image content: screenshots and graphics compress well, photos often do not.
Use PNG as the target when crisp edges or alpha transparency matter. Convert PNG to JPG, WebP, or AVIF when smaller files are more important than exact pixel preservation.
Known metadata support: limited headers, color profiles in newer variants.
Universal support for static PNG; APNG support varies by software.
PNG can preserve decoded pixels losslessly when encoder settings are correct.
Alpha preservation depends on the exact BMP input, decoder behavior, and PNG encoder settings.
Metadata preservation depends on converter settings and target support. Strip GPS/camera metadata for privacy, but preserve ICC profiles when color accuracy matters.
Use PNG when its compatibility, compression, transparency, animation, or workflow behavior is a better fit than BMP for the final use case.
The important settings are output dimensions, quality/compression mode, metadata handling, color-profile preservation, and background color when alpha must be flattened.
Yes, batch conversion is a good fit when the same quality, resize, metadata, and background settings should be applied consistently.
The target format can preserve decoded pixels losslessly, subject to settings.
Metadata preservation depends on converter settings, privacy defaults, and target format support.
