BMP is one of the oldest image formats still in regular use — uncompressed, raw, and supported by basically every Windows program written in the last thirty years. The price of that simplicity is enormous file size: a typical screen-sized BMP is 5–20× larger than a JPG of the same image. Converting BMP to JPG is the right move when you need a much smaller, web-and-email-friendly file and don't need lossless fidelity.
When you'd use it
Email and upload BMPs
Most email gateways and upload forms have size limits that BMPs blow through immediately. Converting to JPG gets the file down to something the recipient can actually receive.
Modernize legacy assets
BMPs from old Windows software, scanning utilities, or industrial cameras pile up fast. Converting them to JPG makes the folder a fraction of the size and brings the assets into the format every modern tool prefers.
Embed in documents and web pages
Word processors, slide decks, and CMS platforms favor JPG over BMP for both performance and compatibility. JPG embeds inline with much smaller document sizes.

Technical notes
BMP is essentially raw pixel data — converting to JPG means re-encoding through a lossy compressor. At quality 90+ the visual difference is invisible to the eye, while the file is typically 10–20× smaller than the BMP. JPG has no transparency support; if your BMP is 32-bit with alpha, transparent regions are filled with the background color (white by default — change it above). For images with sharp edges or text, use JPG → PNG instead, or stay at quality 95+.
Frequently asked
What happens to my BMP files?
Nothing leaves your browser. The conversion runs locally on your device using WebAssembly and the Canvas API. No file is uploaded to a server — including ours.
Is the converted JPG identical to the original?
JPG is a lossy format. The output is visually very close to the original at quality 90+ and considerably smaller. Use the quality slider above to trade size for fidelity.
Is there a file size limit?
There is no hard cap, but very large files (hundreds of MB) may be slow on older devices because everything happens in your browser's memory.
Do you collect data on my file or my use?
Your file is invisible to us — it never leaves your browser. For aggregate page-view counts we use Cloudflare's server-side edge logs (no JavaScript beacon runs in your browser). We display Google AdSense ads on conversion result pages; the AdSense script loads on every page and may set advertising cookies after you accept the consent banner (Google Consent Mode v2 asks first). The ads see the page URL and standard browsing signals — they never see your file, because the file never leaves your device.
How much smaller will the JPG be?
For a typical screen-sized BMP, expect the JPG to be 10–20× smaller. A 12 MB BMP becomes a 600 KB–1.2 MB JPG at quality 90 with no visible quality loss.
Will I lose any quality?
JPG is lossy, so there will always be some loss. At quality 90+ the loss is invisible at normal viewing sizes. Below quality 80 you start seeing compression artifacts in detailed areas.
