PSD vs BMP — Comparison & Free Converter
Fast, instant PSD to BMP conversion. No signup required. Just drop your .psd file and get .bmp in seconds.
Batch Settings
Transparency will be lost
PSD supports transparency, but BMP does not. Transparent areas will be filled with a solid color (typically white). If you need transparency, consider converting to PNG or WebP instead.
HDR data will be tone-mapped
Your PSD file may contain HDR (High Dynamic Range) data. BMP only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
Layers will be flattened
PSD supports multiple layers, but BMP does not. All layers will be merged into a single flat image. Keep your original PSD file if you need to edit individual layers later.
Some metadata may not survive
Your PSD file may contain EXIF, IPTC, XMP, ICC metadata. BMP has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
CMYK → RGB color conversion
Your PSD file uses CMYK color space (designed for print). BMP uses RGB. Colors will be converted — some print-specific colors (especially deep blues and vivid oranges) may shift slightly. For critical color matching, use a calibrated ICC profile.
About PSD to BMP Conversion
PSD or BMP — which format should you use? The answer depends on your needs. Here's a quick breakdown.
PSD is Adobe Photoshop's native format, retaining layers, masks, and editing history. It has limited platform support. BMP is an uncompressed raster format that preserves every pixel but produces very large files. It has universal platform support.
Full Name: PSD uses Adobe Photoshop Document, while BMP uses Bitmap Image. Compression: PSD uses Lossless, while BMP uses None (uncompressed). Transparency: PSD uses Yes, while BMP uses No.
So when should you convert PSD to BMP? This conversion is ideal when you Your PSD file won't open on a recipient's device or in an application, or when you A website, service, or platform only accepts BMP uploads. This conversion helps you improve file compatibility across devices.
PSD supports transparency, but BMP does not. Transparent areas will be filled with a solid color (typically white). If you need transparency, consider converting to PNG or WebP instead. Common misconception: ""My file's transparent background will carry over to BMP"" — in reality, bmp doesn't support transparency. transparent areas become solid (usually white). save as png or webp if you need transparency.

What Happens When You Convert PSD to BMP
Your PSD image is decoded into raw pixel data, then re-encoded as BMP. No quality loss — pixel data is preserved exactly.
Your PSD file is decoded — the compressed/stored pixel data is expanded into raw RGBA (with alpha channel) pixels
Transparency is resolved: transparent pixels are composited onto a white background
HDR data is tone-mapped to standard dynamic range (8-bit per channel)
Pixels are re-encoded using no compression (raw pixel storage)
Metadata (EXIF, ICC profiles) is transferred where BMP supports it
The BMP file is saved and ready for download

Should You Convert PSD to BMP?
When to Convert
- ✓Your PSD file won't open on a recipient's device or in an application
- ✓A website, service, or platform only accepts BMP uploads
- ✓You need maximum device and software compatibility
When NOT to Convert
- ✗You need to preserve transparent areas — BMP doesn't support transparency
- ✗You still need to edit individual layers — BMP flattens everything
- ✗You want to preserve HDR information — BMP only supports standard dynamic range

Common Mistakes When Converting PSD to BMP
"My file's transparent background will carry over to BMP"
BMP doesn't support transparency. Transparent areas become solid (usually white). Save as PNG or WebP if you need transparency.
"BMP will be smaller than my PSD file"
BMP uses no compression, so the output file is often larger than a lossy PSD. If you need a small file, BMP may not be the right choice.
Frequently Asked Questions
Should I use PSD or BMP?
It depends on your goal. PSD preserves full quality. BMP preserves full quality. Choose based on whether file size or quality matters more for your use case.
Is BMP higher quality than PSD?
Not necessarily. PSD supports transparency, but BMP does not. Transparent areas will be filled with a solid color (typically white). If you need transparency, consider converting to PNG or WebP instead. Quality depends on the compression type and settings, not just the format name.
Can I convert PSD to BMP on Mac and Windows?
Yes. CocoConvert is a web-based tool that works in all modern browsers — Chrome, Safari, Firefox, Edge — on any operating system including macOS, Windows, Linux, iOS, and Android.
Is CocoConvert free for PSD to BMP?
Yes. Free users get 5 conversions per hour (250 MB each). Pro subscribers unlock 100 files per hour, 5 GB per file, and priority processing.
What tools does CocoConvert use for PSD to BMP?
CocoConvert uses FFmpeg for audio/video, Sharp for images, and qpdf for documents — the same open-source libraries used by Netflix, YouTube, and major enterprise platforms.
