Convert BMP to WebP

Convert BMP to WebP when a picture from an old program weighs tens of megabytes. BMP stores every pixel in full, while WebP packs the same image into a file many times smaller.

What happens when you convert BMP to WebP

The image keeps its size in pixels; what changes is the storage: instead of a pixel-by-pixel record you get a compressed file. The difference is usually invisible, while the weight drops enough to put the picture on a page or send it by email.

WebP opens in browsers and current editors, but the old program that gave you the BMP most likely will not read it. Keep the source if the file is meant for that program.

• The picture keeps its pixel dimensions.
• The file becomes far lighter than the source BMP.
• Software from years ago does not open WebP.

How to convert BMP to WebP

1. Upload your image in BMP.
2. Select WebP as the result format.
3. Start the conversion.
4. Download the file and view it in a browser.

When a light file is what you need

• Publish a diagram exported by a plant-floor program on a website.
• Email a scan that will not fit into an attachment.
• Free up an archive where hundreds of uncompressed pictures eat the disk.
• Prepare an illustration for a mobile page where loading speed matters.
• Upload an image to a system with a file-size limit.

Other options for BMP files

• When the file is expected in an older format, use the BMP to GIF converter.
• Text from a scan comes out with the BMP to TXT converter.
• A table on the picture lands in fields with the BMP to CSV converter.

FAQ

How much smaller will the file get?

It depends on the picture: a diagram with flat fills gains more than a noisy photo. Either way WebP is markedly lighter than uncompressed BMP.

Does quality suffer?

On diagrams and screenshots the difference is usually invisible. Keep the source BMP if the picture will later be enlarged and edited.

Where might WebP fail to open?

In older graphics editors and the programs that work with BMP. Browsers and current editors display it.
