Free online SKP to BMP converter

A Windows application, legacy print workflow, or raster editor may require a SketchUp model as a BMP image. The conversion renders one selected view as pixels; it does not preserve the editable 3D model.

What the SKP format is

SKP is SketchUp’s native project format. It stores 3D geometry, groups, components, materials, styles, camera views, scenes, and other model data used by architects, interior designers, engineers, contractors, and 3D asset creators.

An SKP file is not an image. SketchUp or software with SKP import support is required to open and edit it. Converting it to BMP renders the current camera view or a selected scene into a flat raster image.

What the BMP format is

BMP is a raster image format associated with Microsoft Windows. It stores pixels at several possible color depths and is commonly used uncompressed, although some BMP variants support compression. Many older Windows applications, basic image editors, documentation systems, and device utilities can read it.

BMP provides direct pixel data and broad compatibility, but files are usually much larger than PNG or JPEG. A 1,920 × 1,080 image at 24-bit color uses approximately 5.9 MiB for pixel data before file headers. BMP is unsuitable when the recipient needs to edit geometry, scenes, materials, measurements, or camera navigation.

Convert the file with 101convert.com

For a one-off conversion, upload the SKP file to 101convert.com, select BMP as the output format, start the conversion, and download the resulting image. Review its dimensions, background, and visible details before using it in production. This option requires no software installation.

Export a BMP from SketchUp

1. Open the SKP file in SketchUp Desktop.
2. Set the required camera position, projection, style, shadows, visible layers or tags, and background. Select a saved scene if the file contains one.
3. Choose File → Export → 2D Graphic.
4. Choose BMP if it is available in the export-format list. Set the image width and height in pixels, then export.
5. If BMP is not offered by the installed SketchUp version, export PNG or TIFF instead, then open that raster file in GIMP, Paint.NET, Photoshop, or another image editor.
6. In GIMP, use File → Export As, enter a filename ending in .bmp, select the required BMP options, and export. In Photoshop, use File → Save a Copy or File → Save As and choose BMP.

Convert an exported image with ImageMagick

After exporting model.png from SketchUp, ImageMagick can create an older, widely supported 24-bit BMP:

magick model.png -alpha remove -alpha off BMP3:model.bmp

BMP3: requests the Windows BMP 3 format. The alpha options remove transparency and composite transparent areas against the current background color, which is normally white. Omit them when the receiving application explicitly supports the source image’s transparency and the selected BMP variant.

Quality and compatibility limits

The result contains one rasterized view only. It does not retain SKP geometry, editable faces, tags, scenes, camera controls, measurements, textures as separate assets, or 3D depth. Export each required scene separately to create multiple BMP files.

Specify the required pixel dimensions during export instead of taking a small screen capture. For printing, calculate pixels from the physical output size and target resolution; enlarging a low-resolution BMP produces soft edges and cannot restore missing detail.

SketchUp can export transparent backgrounds to formats such as PNG, but many 24-bit BMP workflows do not support transparency. Use a solid background for maximum compatibility. Some 32-bit BMP files can contain alpha data, but support varies by application. Keep the PNG or TIFF intermediate when it is needed for transparency, smaller storage, or later raster editing.
