Upload an image to start compressing

BMP (Bitmap) files are uncompressed by design, often resulting in file sizes 10-50x larger than equivalent JPG or PNG images. Our BMP compressor uses the browser Canvas API to re-encode your bitmap as an optimized JPEG — reducing a 10MB BMP to under 500KB without perceptible visual quality loss.

Câu hỏi thường gặp

Nén Ảnh?

✓ 70-80% quality = 60-80% smaller file size with zero visible artifacts.

Lossy vs Lossless?

Lossy compression (JPG, WebP) permanently removes some image data to achieve smaller files. Lossless compression (PNG) reorganizes data without any quality loss. For photos, lossy is usually fine; for logos with text, use lossless.

Batch Nén?

Currently you compress one image at a time to give you full control over quality preview. The entire process takes under 5 seconds per image.

Dimensions change after Nén?

✓ Nén only reduces byte weight; pixel dimensions remain identical.
