About MaiWebTools

MaiWebTools is a collection of free, fast online utilities for everyday image and text tasks — compressing photos, converting formats, counting words, cleaning up lists, and more. Every tool is free to use, with no account, no watermarks and no artificial limits.

Everything runs in your browser

The thing that makes this site different is simple: your files and text never leave your device. Most online tools upload your data to a server, process it there, and send the result back. Ours don't. Every tool on this site does its work locally in your browser using modern web technologies (the Canvas API, WebAssembly and plain JavaScript).

That has three practical benefits:

• Privacy — a private photo or a confidential document is never transmitted, stored or seen by anyone, including us.
• Speed — there's no upload or download wait; a 20 MB photo compresses as fast as your device can process it.
• No limits — since we're not paying to process your files on a server, we don't need to cap file sizes or charge for "premium" tiers.

How the site is funded

MaiWebTools is supported by advertising, which keeps every tool free for everyone. Ads never interfere with the tools themselves, and because processing is local, advertisers never see your files or text.
