About — NoCloud Tools

What this is

NoCloud Tools is a small collection of free, browser-based image utilities: a format converter, a compressor and a resizer. Every tool does its work on your own device using your browser. Your images are not uploaded to any server.

The tools

Image Converter — convert between HEIC, JPG, PNG, WebP and BMP.
Image Compressor — reduce photo file size while keeping it sharp.
Image Resizer — resize to social presets or exact pixel sizes.

Why we built it

Most "online" image tools quietly upload your private photos to their servers to process them. Thanks to modern browser technology (WebAssembly and WebGPU), that is no longer necessary for common image tasks. We wanted tools that are genuinely private, fast, and free of sign-ups and limits.

How it works

When you open an image, your browser decodes it and processes it with the built-in Canvas API — the same technology web pages use to draw graphics. The result is created in memory and offered to you as a download. For HEIC photos, a small open-source helper is loaded the first time to decode Apple's format. At no point is your image sent to a server, because the site has no image-processing backend at all.

How it stays free

The site is supported by advertising. That lets the tools stay free with no account and no watermark. See our Privacy Policy for details on advertising and cookies.
