appkiro.comExamples: BMP images saved from Figma, exports from Photoshop, or assets downloaded from your CMS.
Encode a BMP file into Base64, ready to paste into HTML, CSS, JSON, or a data URL. BMP files are uncompressed and large — Base64 will roughly inflate the size by a third.
Sharing legacy bitmap files inline for diagnostics, archiving, or driver-related debugging.
For pure-text payloads use the Text to Base64 tool.
Does the file leave my browser?
No. Encoding runs in your tab — nothing is uploaded.
Is there a file size limit?
Practical limits depend on browser memory; encoding is comfortable up to ~50 MB.
Should I use BMP for the web?
Convert to PNG or WebP first when targeting web clients — they are smaller and better supported.
