Why convert BMP to JPG?

BMP files are a relic from the early days of Windows — Microsoft introduced the format in the 1980s and it's barely changed since. The defining feature is what BMP doesn't do: it stores pixels uncompressed (or with very basic compression), so a single 1080p BMP can easily be 6 MB or more.

JPG is roughly the opposite. It's a modern lossy format from 1992 that uses sophisticated compression specifically designed for photographs. The same image saved as JPG is typically 50 to 200 times smaller than the BMP version, with no visible quality difference on most photos.

If you've ended up with BMP files from old software, screenshots from legacy Windows tools, or scanned documents, converting to JPG is the easiest way to recover storage space and make them shareable.

About BMP

BMP (Bitmap Image File) is a Microsoft Windows format dating back to the 1980s. It stores raw pixel data with little or no compression, which makes it simple but inefficient. BMP files are uncommon today — they mostly show up from older Windows software, certain scanners, and legacy screenshot tools.

About JPG

JPG is the standard format for photographs. It uses lossy compression that's optimized for natural images, producing dramatically smaller files than uncompressed formats while preserving visual quality. Every modern device and platform supports JPG.

Quality and file size

Expect file size to drop by 95% or more. For photos and natural images, the visual quality difference is essentially invisible. For graphics with sharp edges, text, or large flat color areas, JPG compression can introduce subtle artifacts — in those cases, PNG is often a better choice.

Filesmith runs entirely in your browser using WebAssembly. Files are never uploaded to any server — conversion happens locally on your device, instantly and privately.

Accepts: JPG, PNG, WEBP, AVIF, GIF, BMP, TIFF, SVG, PDF

Frequently asked

Why are BMP files so much larger?

BMP stores every pixel as raw color data with no compression. JPG analyzes the image and compresses areas the human eye is less sensitive to, producing files dozens or even hundreds of times smaller.

Should I use JPG for screenshots?

If the screenshot is mostly text or interface elements with sharp edges, PNG is better — JPG can blur edges. For screenshots of photos or videos, JPG works fine.

Will I lose image quality?

On photographic content the loss is invisible. On screenshots and graphics with hard edges you may see slight blurring near sharp lines.
