BMP files are uncompressed and massive. A single 1920x1080 screenshot takes 5.5MB as a BMP. The same image as a JPG at 90% quality is about 300KB. ConvertFile handles the conversion in your browser with no upload required.

BMP stores every pixel without compression, producing unnecessarily large files. A 1920x1080 photo in BMP format takes 5.5MB of storage. The same image as a JPG at 90% quality is about 300KB, a 95% reduction.
BMP exists mainly as a legacy Windows format. For web use, email, social media, or any modern workflow, JPG is the better choice. It offers near-identical visual quality at a fraction of the file size.

BMP (Bitmap) is an uncompressed image format associated with Microsoft Windows. It stores raw pixel data without any compression, which means perfect quality but very large files. A standard 1920x1080 image takes about 5.5MB in BMP format. BMP is still used in some legacy Windows applications and specialized workflows that require raw pixel access, but it is not suitable for web use or modern sharing.
JPG (JPEG) is the most widely used image format on the web. It uses lossy compression to produce small files, discarding visual information that the human eye is unlikely to notice. At 85-90% quality, most people cannot tell the difference between a JPG and the original. JPG does not support transparency, and re-saving a JPG repeatedly causes gradual quality loss, a process called generation loss.
ConvertFile uses the HTML5 Canvas API to convert images directly in your browser. Your BMP files are never uploaded to a server. The conversion runs on your device's hardware, which is why it finishes in under 2 seconds. Once you close the tab, the converted files are gone from memory.
BMP is uncompressed, so JPG conversion typically reduces file size by 90-95%. A 5.5MB BMP (1920x1080) becomes roughly 300KB as a JPG at 90% quality.
Yes. JPG uses lossy compression, so some pixel data is discarded. At 85-95% quality, the difference from the original BMP is not visible to the human eye.
BMP is mainly used in legacy Windows applications and workflows that require uncompressed pixel data, such as certain scientific imaging tools. For web, email, and general sharing, JPG or PNG are better choices.
Yes. Your browser handles the entire conversion using the Canvas API. No files are uploaded to any server.
Yes. You can convert up to 2 BMP files at once with the free tier. Each file converts independently.
For photographs, 85-90% gives the best balance between file size and visual quality. Since the source BMP is uncompressed, you are starting from the highest possible quality.
PNG gives you lossless compression (50-70% reduction), while JPG gives you lossy compression (90-95% reduction). Choose PNG if you need perfect quality or transparency. Choose JPG if file size is the priority.
No. The output JPG has the exact same width and height as the input BMP. Only the file format and compression method change.
