  1. Step 1

    BMP

    Choose a BMP file from this device.

  2. Step 2

    Browser-local conversion

    The supported geometry is converted in this browser.

  3. Step 3

    USDZ

    Download the USDZ result when conversion is complete.

Direct answer

What happens when you convert BMP to USDZ?

Modelfy converts BMP to USDZ locally in your browser by reading image brightness as a height map and generating an embossed relief mesh. This creates new 3D geometry; it is not a lossless copy of the flat image.

Verify after export

  • Inspect the relief depth and surface detail; brightness is interpreted as height.
  • Confirm scale and units when opening the USDZ file in the destination application.
  • Preview the USDZ in Apple Quick Look to confirm scale and material appearance.

Why choose this BMP to USDZ converter

Local BMP decoding

The selected BMP model file is decoded and rewritten as USDZ on your device; the model file is not uploaded to Modelfy.

BMP to USDZ data report

The compatibility table explains how this browser pipeline rewrites BMP data for USDZ.

USDZ output checks

Geometry is limited; review the implementation detail and verify the downloaded file in your destination tool.

Preview before export

Inspect the browser preview before converting, then use the post-export checklist to confirm the USDZ result.

How to convert BMP to USDZ online

  1. 01

    Upload your BMP file

    Drag and drop the file into the converter, or click Upload. BMP inputs up to 25 MB are processed locally.

  2. 02

    Convert to USDZ

    Preview the model in 3D, then click Convert. The conversion runs locally in the browser; processing time depends on model complexity and device resources.

  3. 03

    Download the USDZ file

    Your USDZ file downloads straight to your device, ready for the next tool in your pipeline.

About the BMP file format

Bitmap Image

The Windows bitmap format stores raw, uncompressed pixel data. Files are large but perfectly lossless, with every pixel value preserved exactly as authored.

That pixel-exactness suits height-map workflows where each gray value should map to a precise relief height.

Format reference: Microsoft bitmap storage documentation

Strengths

  • Exact uncompressed pixels
  • Dead-simple structure
  • Legacy Windows support

Commonly used for

  • Precise height maps
  • Legacy scanner output
  • Pixel art relief models

About the USDZ file format

Universal Scene Description (zipped)

USDZ packages Pixar’s Universal Scene Description into a single uncompressed ZIP archive. Apple adopted it as the native AR format for iOS: Safari, Messages, and Mail open USDZ files directly in AR Quick Look.

For e-commerce and product visualization, shipping a USDZ next to a GLB covers both Android (Scene Viewer) and iOS (Quick Look) AR experiences.

Format reference: Alliance for OpenUSD USDZ specification

Strengths

  • Native AR support on iPhone and iPad
  • Single-file scene with materials
  • Backed by Pixar’s USD ecosystem

Commonly used for

  • iOS AR Quick Look experiences
  • E-commerce product AR
  • USD pipeline delivery

Frequently asked questions

Is my BMP model file uploaded to a server?

The selected BMP model file is processed by the browser and is not uploaded to Modelfy. Website code and static assets still load over the network like a normal web page.

How does a flat image become a 3D USDZ model?

The image is read as a height map: bright pixels are raised and dark pixels stay low, producing an embossed relief on a solid printable base. High-contrast images with a clear subject give the best results.

Will I lose quality converting BMP to USDZ?

The source image is used as a height map to generate new relief geometry, so the result is a 3D interpretation rather than an identical copy. Image resolution, contrast, and the target format determine how much surface detail is preserved.

Is the BMP to USDZ converter free to use?

Yes. The browser viewer, converter, and local 3D text tool require no account and add no watermark. Input limits vary by format, up to 50 MB; AI model generation is a separate credit-based product.

What is the maximum file size?

BMP inputs up to 25 MB are accepted. The format-specific limit keeps browser-local parsing bounded; actual processing also depends on available memory, model complexity, and device performance.

Why can’t some USDZ files be opened in the browser?

USDZ archives can contain ASCII (.usda) or binary crate (.usdc) data. Browsers can parse the ASCII variant, but binary USDC (which many Apple tools export) has no JavaScript parser yet. If your file fails, convert from the original GLB instead.

From a single image to a production-ready 3D model

These browser tools stay free for viewing and converting files you already have. When the model does not exist yet, Modelfy generates a textured mesh from one reference image — the first one is free.
