How to convert BMP to JPG
BMP is a Windows bitmap format that stores image data with no compression, which keeps every pixel intact but produces files that are 10 to 30 times larger than an equivalent JPG. Converting BMP to JPG is the standard way to shrink these files to a size that works for email attachments, web uploads, and media libraries.
The conversion runs directly in your browser using WebAssembly image processing. Your image is never sent to a server, so there is no upload wait, no queue, and no size limit imposed by server quotas. Drop the file in, adjust the quality slider if you want, and download the JPG.
Upload the BMP file
Click or drag your .bmp file into the drop zone. The browser reads the uncompressed pixel data locally.
Set JPG quality
Use the quality slider to balance file size against image fidelity. Quality 85 is a good default; go higher for print, lower for thumbnails.
Convert
The WebAssembly encoder applies JPEG compression to the raw pixel data. The process is fast even for large bitmaps.
Download the JPG
Click Download to save the .jpg file. It will be substantially smaller than the original BMP.
Frequently asked questions
How much smaller will the JPG be compared to the BMP?
At quality 85, a typical JPG is 10 to 25 times smaller than the equivalent BMP. A 10 MB BMP might become a 500 KB to 1 MB JPG, depending on image content.
Does converting BMP to JPG lose quality?
JPG uses lossy compression, so some fine detail is discarded. For photographic images, the difference is rarely visible at quality 80 or higher. For graphics with sharp text or solid colors, the loss is more noticeable.
Is my image uploaded to a server?
No. Processing is entirely in your browser via WebAssembly. Your file never leaves your device.
What is the maximum BMP file size?
There is no server-imposed size limit because conversion is local. Device memory sets the practical ceiling.
Should I convert to PNG instead of JPG?
Convert to PNG if your image has sharp edges, text, or a transparent background, since PNG is lossless. Use JPG for photographs and continuous-tone images where the smaller file size matters more.
