How to Convert Files

Convert VIPS native images to and from common formats in your browser, with all processing performed locally on your device.

What a VIPS file holds

VIPS is the native image format of libvips, a fast, low-memory image-processing library. The format is designed to work hand in hand with the library's streaming architecture, storing image data in a way libvips can read and write efficiently as it processes very large images.

The point of a native format is speed and scale. libvips is built to handle images too big to hold in memory at once, processing them in regions, and its own format lets it save and reload intermediate results without the overhead of encoding to a general-purpose format. It records the pixel data along with the metadata libvips needs to resume work.

Strengths and limits

Inside a libvips pipeline the VIPS format is ideal: it matches the library's memory model, so reading and writing are quick and cheap, which matters when working with gigapixel images.

It is a working format, not a delivery one. Support is essentially limited to libvips and software built on it, so images meant to be shared or viewed elsewhere are exported to a standard format. It also tends to be large, since it favours fast access over small size.

History of VIPS

VIPS was first developed in the early 1990s by John Cupitt as part of the libvips project. It was created to address the challenges of processing large images efficiently, particularly in scientific and medical imaging contexts. The format evolved alongside the library, which focused on low-memory usage and high-speed processing, making it suitable for gigapixel images.

Over the years, VIPS gained traction in various industries, leading to the development of tools and integrations that support the format. Its compatibility with other image formats and libraries has facilitated its adoption in workflows involving large datasets. The ongoing enhancements to libvips have helped standardize VIPS usage, making it a preferred choice for high-performance image processing tasks.

Practical Usage of VIPS

Choose VIPS when working with very large images that require efficient memory management and fast access. Common workflows include processing satellite imagery, medical scans, and high-resolution photographs. VIPS excels in scenarios where performance is critical, particularly in batch processing pipelines that handle multiple large images in a streaming fashion.

Be aware of compatibility issues when converting to and from VIPS. Some formats may lose metadata or color profiles during conversion. It is advisable to use libvips or compatible tools to ensure proper handling of image data. When converting from formats like JPEG or PNG, consider the potential for increased file size in VIPS. Keep in mind that VIPS typically does not support compression, so be prepared for uncompressed output.

Working with VIPS files

You will encounter the VIPS format when using libvips directly or through the many applications built on it, particularly for large-image tasks such as generating deep-zoom tiles.

To view or distribute the result, export it from libvips to a standard format: PNG or TIFF for lossless output, or JPEG for photographs. The library performs the conversion as part of its normal save operation.
