Batch convert large BMP bitmap files to compressed JPG images online. Keep the original pixel dimensions, start every file immediately, and download each JPG with no signup.
Eller slipp filer her. Maksimal filstørrelse er 1 GB.
Add one or several BMP files, choose JPG once, and start the batch conversion.
The output keeps the same canvas size, but JPG changes how the pixels are stored. These are the practical tradeoffs to check before converting a batch.
BMP commonly stores pixel data with little or no compression, while JPG uses lossy compression to discard some image detail. Photographic and high-resolution BMP files are often much smaller as JPG, but the exact result depends on the source. A small indexed-color BMP can even be smaller than its JPG copy.
The converter keeps the source width and height. JPG still re-encodes the pixels, so fine texture, text, and hard edges can show compression artifacts even when the pixel dimensions stay unchanged.
JPG has no alpha channel. Transparent pixels in a 32-bit BMP are flattened into opaque pixels and may appear black depending on the bitmap data. Use BMP to PNG instead when transparency must remain.
Select multiple BMP files, apply JPG as the target, and start them in the same browser workflow. Each file starts immediately and finishes with its own JPG download.
Add one or more BMP files. You can choose several files at once or drag them into the converter, with a 1 GB limit for each file.
Choose JPG as the output format and start the conversion. Every selected BMP begins processing immediately.
Download each completed JPG file to your device.
Usually, especially for 24-bit photos and high-resolution bitmaps, because JPG uses lossy compression. The saving is not guaranteed: image detail, dimensions, color mode, and the BMP encoding all affect the result, and some small indexed BMP files can grow after JPG conversion.
Yes. Verified standard, grayscale, indexed-color, alpha, and 4096 × 3072 BMP fixtures kept their original width and height in the JPG output. The pixels are recompressed, but the page does not deliberately resize the image.
JPG cannot store transparency. Alpha pixels become opaque and transparent areas may appear black depending on the source bitmap. Convert BMP to PNG when you need to preserve transparency.
Yes. Add multiple BMP files, choose JPG for the batch, and start the conversion once. Each selected file begins immediately and receives a separate downloadable JPG when it finishes. The upload limit is 1 GB per file.
This BMP to JPG workflow currently uses the encoder default and does not show a JPG quality slider. For manual control, use the Image Compressor after conversion: lower JPEG quality normally creates a smaller file with more visible artifacts, while higher quality keeps more detail in a larger file.
Choose PNG for transparency, logos, screenshots, text, line art, or images you expect to edit repeatedly. Choose JPG when broad compatibility and a smaller photographic image are more important than lossless pixels or transparency.
Convert BMP, JPG, PNG, WebP, AVIF, HEIC, TIFF, and other image formats from one hub.
Browse every available conversion into or out of the BMP bitmap format.
Create compatible JPG images from BMP, PNG, WebP, HEIC, TIFF, and camera formats.
Choose lossless PNG instead when the bitmap contains transparency, text, line art, or sharp graphics.
Convert another common lossless image format into a smaller, widely compatible JPG file.
Compare output size and use a JPEG quality slider when you need more control over compression.
BMP is a simple bitmap format that is often uncompressed and therefore large.
JPG uses lossy compression and does not support transparency.
The BMP pixels are decoded and written using JPG compression and color capabilities.
