Why BMP files are impractically large
BMP (Bitmap) stores every pixel without any compression whatsoever. A simple 1920×1080 screenshot is about 6 MB as BMP — the same image is typically 200-400 KB as JPG. This makes BMP impractical for email, web upload, cloud storage, or sharing. Converting to JPG applies efficient lossy compression that reduces file size by 90-95% with negligible visible quality loss.
Instant browser conversion
OnlyFiles converts BMP to JPG entirely in your browser. Your image is loaded into the Canvas API and exported as a high-quality JPG — no server upload needed. This means the conversion is instant (no network latency) and completely private. The output uses 92% quality setting, which provides an excellent balance between file size reduction and visual fidelity.
When to use this
- Shrink a massive BMP screenshot down to a shareable size
- Convert old BMP images for uploading to the web or social media
- Email an image that was saved as BMP without hitting size limits
Frequently asked questions
Why are BMP files so large?
BMP (Bitmap) stores every pixel without any compression, making files extremely large. A simple screenshot can be 5-10 MB as BMP. Converting to JPG applies compression that typically reduces the file to 5-10% of the original size.
How much will converting BMP to JPG reduce the file size?
Dramatically. A 10 MB BMP will typically become 200-500 KB as JPG — a 95% or greater size reduction. This makes the file practical for email, web upload, or sharing.
Is there any quality loss?
JPG uses lossy compression, so there is a very small quality reduction. For photos and screenshots, the difference is virtually invisible. If you need perfect quality, convert to PNG instead.
