Why convert PSD to BMP?
- BMP is supported far more widely than PSD, so the file is easier to open, share and upload.
- BMP is made for older Windows programs, embedded devices and tools that need raw pixels.
- No Photoshop needed: the file is opened on our servers and you download a ready-to-use BMP.
What to expect when converting PSD to BMP
- BMP 无法存储透明度，因此透明区域会用您在“设置”中选择的背景色填充（默认为白色）。
- Layers are merged: you get the image as it looks with all visible layers combined.

Frequently asked questions
- How do I convert PSD to BMP?
- Upload your PSD file above. It is converted to BMP automatically (change the output format or quality in the Settings tab if you need to), then click Download. There is nothing to install.
- Does converting PSD to BMP lose quality?
- No. Both formats are lossless, so every pixel is kept exactly.
- Will the BMP keep the transparent background?
- 不会。BMP 无法存储透明度，因此透明区域会用您在“设置”中选择的背景色填充（默认为白色）。
- PSD or BMP: which should I use?
- Use PSD for editing in Photoshop with layers, masks and effects intact. Use BMP for older Windows programs, embedded devices and tools that need raw pixels. Keep in mind the main drawback of BMP: very large files and no transparency.
- 什么是 PSD 文件？
- PSD 保留 Photoshop 的每个图层、蒙版和调整，让设计始终可编辑。在 Photoshop 之外，大多数应用无法显示它，因此分享时需要一份合并图层后的副本。
- Can I convert PSD to BMP without Photoshop?
- 可以。PSD 文件在我们的服务器上打开，因此您无需安装 Photoshop 或任何其他软件。上传文件，然后下载转换好的 BMP。
- Is the PSD to BMP converter free?
- Yes. Convert, preview and download a single result without creating an account. Premium adds batch conversion (many files into one ZIP) and larger uploads.
