PSD to BMP Converter
Turn PSD files into BMP in seconds. Everything happens on your device: nothing is uploaded, and there's no limit.
Your images are processed in this browser tab and never uploaded.
Why convert PSD to BMP?
Not everyone has Photoshop, and PSD files are too big to share.
Some older programs, printers and embedded devices only accept uncompressed BMP files.
What to expect
- Layers are flattened into one image, exactly as the document looks with its visible layers. The PSD needs to be saved with “Maximize compatibility” on (Photoshop's default).
- BMP has no transparency, so transparent areas become white.
- BMP is uncompressed, so the file will be much larger than the original.

About the formats
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.
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.
Frequently asked questions
How do I convert PSD to BMP?
Drop your PSD files into the box above (or tap Select files), check the options, then press Convert. Each BMP downloads on its own, or you can download them all as one ZIP file.
Are my files uploaded anywhere?
No. The conversion runs entirely in your browser on your own device. Your PSD files are never sent to a server, so they stay private, and it works even on a slow connection once the page has loaded.
Is there a limit on how many PSD files I can convert?
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.
Do I need Photoshop?
No. The PSD is read in your browser. You get the flattened image as it appears in Photoshop. Files saved without “Maximize compatibility” don't contain that image; re-save them with it on.
Will I lose quality converting to BMP?
No. BMP is lossless, so the converted image keeps every pixel of the original.
Does it work on iPhone and Android?
Yes. It works in Safari, Chrome, Firefox and Edge on phones, tablets and computers. Nothing to install.
