Image editing software ranges from quick crop-and-resize utilities to full raster and vector design suites. The right tool depends on the task: raster editors work pixel by pixel and are best for photos, while vector editors work with mathematical shapes that scale to any size without quality loss, which is why they're the standard for logos and icons.
File format choice affects both quality and workflow. RAW formats from cameras preserve the maximum sensor data for editing flexibility, while JPEG is a lossy, ready-to-share format. PNG supports transparency and is lossless, which is why it's preferred for graphics and screenshots over photos.
This hub covers raster editors, vector tools, and format converters, along with guides for recurring tasks such as batch-resizing images, removing a background, and converting between RAW and JPEG.
