About the formats
BMP (Windows Bitmap, 1990) is a simple, uncompressed Windows format. Files are large because every pixel is stored as-is, but almost any program, including very old software and embedded devices, can read it.
PSD (Adobe Photoshop Document, 1990) is Photoshop's own working format. It keeps layers, masks and editing data, which makes files large and only readable in software that understands Photoshop documents.
Frequently asked questions
How do I convert BMP to PSD?
Drop your BMP files into the box above (or tap Select files), check the options, then press Convert. Each PSD downloads on its own, or you can download them all as one ZIP file.

No. Convert as many as you like, for free, without signing up. Very large batches are processed one after another so your browser stays responsive.
Will I lose quality converting to PSD?
No. PSD is lossless, so the converted image keeps every pixel of the original.
Does it work on iPhone and Android?
