How JPG to BMP Conversion Works

JPG is an image format: it uses lossy DCT compression that permanently discards fine pixel detail to achieve small file sizes, ideal for photographs. BMP is an image format that stores uncompressed pixel data in a simple row-by-row grid, resulting in large file sizes but zero quality loss. This conversion changes the file's encoding, compression method, and supported feature set. Colour profiles and orientation metadata are preserved in the output. Converting between these two formats is common when the source application does not support BMP natively or when the target platform only accepts BMP. 1converter processes this conversion server-side using open-source tools. Files are transferred over HTTPS, converted on secure cloud servers, and automatically deleted after 24 hours.

When to use Low/Medium:

  • •Web uploads and social media sharing
  • •Email attachments with size limits
  • •Quick previews and thumbnails

When to use High/Maximum:

  • •Professional printing and publishing
  • •Archive and long-term storage
  • •When quality is more important than size

Image Tip: For photos, Medium quality offers the best balance. For graphics with text or sharp edges, use High or Maximum quality to preserve clarity.

Frequently Asked Questions

Everything you need to know about converting JPG to BMP

BMP is typically uncompressed, but converting from JPG cannot restore details lost during the original JPEG lossy compression. It mainly removes further compression and stores the existing pixels in BMP form.
JPEG uses lossy compression to reduce size, while BMP commonly stores pixel data without compression (or with optional simple compression). As a result, BMP files are often significantly larger for the same dimensions.
BMP is a raster bitmap format and is broadly editable for pixel-based workflows, but it’s not the same as an editable layered format. Many editors treat BMP as a flattened image and preserve pixel values as stored.
No—JPG does not support an alpha (transparency) channel, so the BMP output will be opaque. Any transparency would need to be added separately after conversion using an editor that supports alpha.
