Kaaf11 provides a collection of free online image tools for common image conversion, optimization and editing tasks. You can convert images between popular formats, reduce image file sizes, change image dimensions, crop unwanted areas, rotate images and flip images without installing desktop software.

These browser-based image tools are designed to keep image editing simple and accessible. Whether you need to prepare an image for a website, reduce a file before uploading it, change its dimensions or convert it to a different format, you can choose the tool that matches your task.

Different websites, applications and devices may require different image formats. Our image conversion tools make it easy to convert images to PNG, JPG, JPEG or WebP.

PNG can be useful when you need lossless image output, while JPG and JPEG are commonly used for photographs and general-purpose images. WebP is a modern image format commonly used on websites where smaller image files can help improve page performance.

Large image files can take longer to upload, store and load on websites. Image compression reduces the file size of an image while aiming to preserve useful visual quality.

Kaaf11 includes general image compression as well as dedicated JPG/JPEG, PNG and WebP compressors. Choose the format-specific compressor when you already know the image format you want to optimize.

Image dimensions matter when preparing images for websites, social media, documents and other digital platforms. The Image Resizer lets you change the width and height of an image to suit your requirements.

For quick editing, you can also crop unwanted areas, rotate an image to the correct orientation or flip an image horizontally or vertically. These tools are useful for everyday image preparation without requiring a full desktop image editor.
