Image Tools
Image tools run on an HTML canvas in your browser for compress, resize, crop, convert, and related edits.
Start here: Image Compressor for file size; Image Resizer for pixel dimensions; format converters when you need WebP/JPG/PNG.
Transparency and animation are not always preserved — read each tool’s limitations before batch work.
