Compression Level

Choose a compression level to reduce output file size. Lossy method reduces file size at the expense of image quality

Image Quality

100

Lower values give better compression (at the cost of image quality)

Choose a color to make transparent?

Yes

Use this option to make a transparent background in your PNG output.

Choose a color to make transparent

Choose a color using the color picker or enter a hex color value. (eg. #FFFFFF)

Auto Orient – Correctly orient the image using the gravity sensor data stored in EXIF

Strip Metadata – Strip the image of any profiles, EXIF, and comments to reduce size

Understanding DIB and JXL File Formats

What is DIB File Format

DIB (Device Independent Bitmap) is a Windows raster image format that stores bitmap images independently of device-specific color representation. It typically holds uncompressed or lightly compressed pixel data with color palettes optimized for consistent display on Windows devices.

What is JXL File Format

JXL (JPEG XL) is a next-generation, royalty-free image format designed for superior compression and excellent visual quality. It supports both lossy and lossless modes, HDR, transparency, wide color gamut, and animation. JXL provides smaller file sizes than JPEG and AVIF while maintaining or improving quality, making it ideal for responsive web design and modern imaging needs.

Why Convert DIB to JXL?

Superior compression reduces file size without noticeable quality loss.
Supports both lossy and lossless compression for versatile needs.
Retains advanced features including HDR, alpha transparency, and animation.
Optimized for modern web environments and responsive images.
Future-proof format gaining broad industry support.
Enables faster image loading and bandwidth savings.
Maintains high visual fidelity for professional and personal use.

When Should You Convert DIB Files to JXL?

Preparing images for high-quality, bandwidth-efficient web use.
Archiving images with both lossy and lossless compression flexibility.
Creating responsive images that adapt to different devices and screen sizes.
Sharing images requiring HDR and alpha transparency support.
Transitioning legacy bitmap images to cutting-edge image formats.

DIB to JXL File Comparison

Feature	DIB (Device-Independent Bitmap)	JXL (JPEG XL)	Winner
File Size	Typically large; raw or lightly compressed bitmap data	Highly efficient; much smaller at similar visual quality	JXL
Compression	Usually uncompressed BI_RGB; optional RLE/bitfields variants	Advanced lossy and lossless compression with progressive decoding	JXL
Web Support	Not supported in browsers; mainly for Windows APIs/clipboard	Emerging browser support; not yet universal	JXL
Quality	Exact, lossless pixels at source bit depth	Visually excellent and can be truly lossless	Tie
Use Cases	In-memory bitmaps, GDI rendering, legacy interchange	Web delivery, photography, and archival with high efficiency	Depends
Color & HDR	Supports 1–32-bit color; alpha via bitfields; no HDR metadata	Wide gamut, 8–16+ bit depth, alpha, animation, and HDR support	JXL

Before & After Example

Before Conversion (DIB):
DIB images hold detailed pixel data usually uncompressed, leading to large file sizes. They are perfect for editing and storage within Windows environments but inefficient for web or modern use due to lack of compression.

After Conversion (JXL):
Converted JXL images compress significantly—up to 55% smaller than JPEG—with no visible loss of quality in many cases. JXL supports advanced features like HDR and animation and is optimized for modern web and device compatibility, providing both improved storage efficiency and enhanced image fidelity.
