BMP Image Editor

The BMP Image Editor provides in-browser processing for standard uncompressed BMP files. It targets designers, game developers, and asset teams who require pixel-precise edits without desktop software. The tool accepts BMP inputs and returns edited bitmaps or export-ready variants.
Under the hood, it validates BMP headers, decodes pixel arrays, and applies edits at the pixel level. Core operations include crop, resize with a chosen interpolation method, and color depth conversion. Paletted 8-bit images are handled with palette awareness, and 24-bit or 32-bit inputs are converted with careful mapping to preserve visual integrity as formats allow.
Output options include BMP by default, with optional PNG or JPEG exports. The system updates image dimensions, color depth, and file metadata in the result. It supports common configurations (8-bit, 24-bit, and 32-bit BMP) and rejects unusual, nonstandard BMP variants to maintain pixel accuracy and predictable results.
Use cases cover sprite sheets for games, thumbnails for web galleries, and asset previews in development pipelines. The tool emphasizes deterministic edits, in-browser processing to avoid software installs, and clear export controls for cross-format workflows, making BMP-specific edits accessible to a broad audience.
