How to convert JPG to BMP

The JPG is decoded on your device and re-encoded as BMP with the browser's own graphics engine. Because nothing is uploaded, even dozens of photos convert quickly and privately. BMP stores uncompressed pixels, which some legacy and industrial software still requires.

Step 1: Choose your JPG file
Drag and drop a .jpg, .jpeg, .jfif file onto the converter or click to browse. It works on desktop, tablet and phone.
Step 2: Convert to BMP
Each image is converted to BMP immediately.
Step 3: Download the BMP
Save each result individually, or download everything as a single ZIP when you convert several files.

Good to know

Converting to BMP is lossless from here on, but it cannot restore detail already lost in the JPG compression, and files are usually larger.
Photo metadata (EXIF, GPS location) is removed from the converted image, which is good for privacy.

Why use this JPG to BMP converter?

Batch conversion: drop several images at once and download a ZIP.
Nothing is uploaded, so personal photos stay private.
Original resolution is kept.
No watermark, no account, no app to install.

Is it free?

Yes. Converting JPG to BMP is free, with no watermark, signup or email required. Local conversions have no artificial file-size or daily cap; the practical limit is your device.

Is my file uploaded?

The JPG file is processed entirely in your browser. It is never uploaded, never stored and never seen by anyone, so this is safe for confidential files.

About the formats

What is JPG?

JPG, or JPEG, is an image format named after the Joint Photographic Experts Group, which created the standard in the early 1990s. It uses lossy compression that discards detail the eye barely notices, so photos take up far less space. It does not support transparency or animation, and every time you re-save a JPG it can lose a little more quality.

Use JPG for photographs and images with smooth colour gradients that you want to share, upload or email at a small size. Avoid it for logos, screenshots with text or anything that needs a transparent background; PNG handles those better.

What is BMP?

BMP, also called DIB (device-independent bitmap), is a raster image format that Microsoft introduced with Windows. It usually stores every pixel uncompressed, so image quality is untouched but files are very large. The format is simple and widely readable, yet it offers little that PNG does not do better.

Use BMP only when an old program, a device or an embedded system specifically requires it. For everyday use, convert BMP files to PNG to keep the same quality at a fraction of the size, or to JPG for photos.

No additional quality is lost: BMP stores the decoded pixels losslessly.

Is the image resolution changed?

No. The BMP keeps the exact width and height of the original. Use the Resize Image tool if you need smaller dimensions.

Is it safe to convert jpg to bmp here?

Yes. The work happens on your own device with WebAssembly and browser APIs, so the file is not uploaded at all. You can even disconnect from the internet once the page has loaded.
