Image to BMP Converter
Convert JPG, BMP, WebP, GIF or other supported images to Windows Bitmap (BMP) files in your browser. Add one file or a batch, resize if needed, and download your results without uploading originals.
Drop your images here
Select one image or several files at once.
JPG, BMP, WebP, GIF, BMP & AVIF
Up to 30 files · 25 MB each · 150 MB per batch
Your images stay on your device. Files are converted locally in your browser.
BMP format details
- BMP is an uncompressed Windows Bitmap format, so files are usually larger than JPG or WebP.
- Transparent pixels are rendered using the selected background colour.
- Animated images become one still frame.
- Output is a flattened raster image; layers and editable vectors are not preserved.
Ready to convert.
How to convert your images
Use the same workflow for a single photo, product images or a folder of screenshots. No installation is needed.
Choose the output
Choose JPG, BMP or WebP beside each file, or use one batch format. Open Options on any row to set that image’s quality, maximum dimensions and JPG background colour.
Convert and download
Check each result’s dimensions and file size. Download images individually or save all successful conversions in one ZIP file.
Why convert an image to BMP?
The right format depends on what is in the image and where it will be used. Converting a file does not automatically make it smaller or sharper.
Uncompressed Windows Bitmap output
BMP stores rendered pixel data without JPEG compression. It is useful for Windows software, print workflows and applications that specifically require a bitmap file.
Straightforward pixel output
Useful for screenshots, diagrams and graphics with transparent areas. BMP output uses lossless compression, but converting a JPG to BMP cannot restore details already lost.
When a bitmap is required
Choose BMP when a desktop application, print workflow or legacy system specifically asks for a Windows Bitmap file.
What this converter supports
| Feature | Support |

| Animation | A single still image; animation is not preserved |
| Unsupported inputs | HEIC/HEIF, TIFF, SVG, PSD, RAW and PDF |
Keep control of quality and file size
Start with the default quality setting, then inspect the result. A lower JPG or WebP quality can reduce file size, but may also introduce visible artefacts around text or fine details. Use BMP when keeping those details matters more than saving space.
For a smaller image, choose “Fit within a maximum size”. A 4,000 × 3,000 photo fitted within 1,920 × 1,920 becomes 1,920 × 1,440. The converter keeps the aspect ratio and does not crop or enlarge your image. Set dimensions in Batch settings, or open a file’s Options to resize that image only. Custom file options remain in effect until you select Use batch settings in that file’s Options.
Your files stay on your device. The converter reads the files you select and creates downloads in your browser. It does not send image files to a conversion server or save them to an account. Clear the queue or close the page when you finish.
Use original files for print or colour-critical work. This tool creates browser-rendered images and does not preserve original EXIF metadata, camera information, colour profiles, layers or print-DPI settings.
BMP conversion notes
| Conversion | When to use it | Before you download |
|---|---|---|
| JPG to BMP | Create a Windows Bitmap copy for software that requires BMP. | Choose a background colour for transparent source pixels. |
| PNG to BMP | Convert screenshots and graphics to an uncompressed bitmap. | Expect a larger file than PNG in many cases. |
| JPG to BMP | Create a BMP copy for a workflow that requires it. | The file may grow; missing detail and transparency are not restored. |
| WebP to BMP | Use a WebP image in a Windows Bitmap workflow. | Transparency is rendered using the background colour. |
| GIF to BMP | Create a still BMP from a GIF. | Animated GIFs become one frame. |
Add mixed source formats in one batch. Set the background colour and optional maximum dimensions, then select Convert images. Your originals remain unchanged.
Frequently asked questions
Can I convert several images at once?
Yes. Add up to 30 images, choose a batch output format and select Convert images. Each file has its own output-format selector and Options button. Use batch settings for a consistent result, or customise individual images before converting. Download the successful results separately or together as a ZIP.
Is this image converter free?
Yes. This converter has no payment step, account requirement or watermark. The file, batch and image-dimension limits shown above help keep conversion manageable on your device.
Will converting my image reduce its quality?
BMP output is uncompressed after rendering, but it cannot restore detail already lost in a compressed source such as JPG or WebP. Resizing, colour handling and earlier compression can still affect the result; converting a low-resolution image cannot recover missing detail.
How do I convert WebP to JPG or BMP?
Add your WebP images, confirm BMP is selected as the output, choose a background colour if needed, then convert and download the results.
Can I convert HEIC photos from an iPhone?
This version does not decode HEIC or HEIF files. Export a JPEG, PNG or BMP copy from your photo app first, then add that file here. Renaming a .heic file to .jpg does not convert it.
Why is my converted file larger?
File size depends on dimensions, content, quality and compression. A BMP made from a JPG can be much larger. A high-quality WebP may also exceed the original size. Lower the JPG/WebP quality or resize the image if a smaller download is your priority.
Why did one image fail to convert?
The file may be damaged, unsupported by your browser or larger than the size limits. Other valid files in the batch can still finish. Read the message beside the failed file, try smaller dimensions or use a supported JPG, BMP or WebP original.
Does it work on mobile?
Yes, in browsers that support the required image formats. Tap Select images to open your device’s file picker. For large photos, use smaller batches on phones. Your browser may ask where to save an image or a ZIP file.
