How to use it
- 01Choose up to 8 supported images. File contents are checked instead of trusting the extension.
- 02Keep the required output format and adjust relevant optional settings if needed.
- 03Convert, review dimensions and actual file size, then download successful results.
Choose this conversion for the right reason
Some desktop applications or device workflows ask for a bitmap. This tool writes a genuine uncompressed 24-bit BMP with row padding. It does not write indexed or alpha-capable BMP variants, and the file is often larger than PNG or JPG.
Files are processed one at a time in a worker to limit peak memory. Invalid or unsupported images are reported individually. Conversion changes format; it does not guarantee compression, remove a background or recreate missing source detail.
Practical check: Confirm the recipient accepts a 24-bit BMP, rather than a specific indexed or monochrome variant.
Useful details and limits
Exports an uncompressed, 24-bit BMP. Transparent areas use your chosen background color. Limits: 20 MB per file, 40 MB input per batch and 120 MB combined results. General decoding is capped at 20 million pixels and 16,000 pixels per side. Metadata and color profiles are not preserved. Originals are not changed. A failed file receives its own error and does not stop the other conversions.
Questions about this tool
What kind of output does this tool create?
Exports an uncompressed, 24-bit BMP. Transparent areas use your chosen background color.
What should I check before using the converted file?
Confirm the recipient accepts a 24-bit BMP, rather than a specific indexed or monochrome variant.
Are my images uploaded or stored?
No. Files, previews, conversion and ZIP creation remain on your device. A codec may load from Tool Fera when needed, but your image bytes are not sent with that request.
Understand the workflow
- JPEG, PNG, WebP or AVIF: choose the format for the job
Choose an image format by content and destination. Compare photos, text, transparency and browser support without assuming one format is always smallest.
- Image dimensions versus file size: pixels are not megabytes
Understand pixels, bytes, aspect ratio and compression. Choose resizing or quality changes for a real upload requirement and compare the final image.
