Free Online Image Tools – Convert, Compress & Resize Images

Images are everywhere — website headers, social media posts, client deliverables, product photos. But managing them often means juggling formats, fighting file sizes, and wrestling with dimensions. Tools Oasis puts a full image toolkit at your fingertips, and every tool runs 100% in your browser so your photos never touch a remote server.

Shot a batch of photos on your iPhone? The HEIC Converter instantly transforms Apple's proprietary format into universal JPG, PNG, or WebP. Need to switch between JPG, PNG, and WebP for different platforms? The format converters handle it in a single drag-and-drop. When page speed matters, the Image Compressor squeezes file sizes down dramatically while preserving visual quality — ideal for blogs, e-commerce listings, and email campaigns.

Pixel-perfect dimensions are just as important as file size. The Image Resizer lets you scale images to exact widths and heights, with aspect-ratio locking so nothing gets stretched or distorted. Designers and brand managers will love the Image Color Picker, which extracts dominant colors and palettes from any uploaded photo — great for matching brand assets or building mood boards.

Because every conversion happens locally using Canvas and WebAssembly APIs, there are no upload queues, no daily limits, and no watermarks. Your images stay on your machine from start to finish. Whether you're a developer optimizing assets, a marketer prepping social graphics, or just someone who needs to email a smaller photo, these tools have you covered.
