About ImgTool.app

What you can do on ImgTool.app

The site includes a mix of tools designed around common real-world needs:

• Music Visualizer videos: turn audio into clean, export-ready visual videos for YouTube, promos, and social clips.
• Image tools: resize, optimise, convert and prepare images for the web and social platforms.
• Simple workflows: quick presets, preview-first controls, and exports that don’t require sign-ups.

You can see the full list on the All Tools page.

Privacy & file handling (how it works)

ImgTool.app is designed so that your media can stay on your device. Most tools process files client-side using modern browser features during normal editing and export work.

• Your media stays on your device — your images, audio, and video are processed locally in your browser and are not uploaded to ImgTool.app servers during normal use.
• No accounts required — you can use the tools without creating a login.
• Local exports — results are generated in the browser and saved by you.
• Analytics stays consent-based — if you accept analytics, Google Analytics 4 records broad usage events such as page views, button clicks, tutorial steps, feature categories, export events, coarse duration ranges, and whether this browser looks new or returning. It does not upload your audio, images, video files, filenames, exact media length, or exported files.
• You are responsible for the media you use — if you upload copyrighted audio, video, artwork, logos, or other material, you need the rights or permission to use and distribute it.

For the legal/technical detail, read the Privacy Policy.

Performance expectations

Because processing happens on your device, speed depends on your browser and hardware. For example, exporting longer videos or using heavier effects may take more time on older machines.

• Keeping the tab visible can help (background tabs may be throttled by the browser).
• Lower FPS or simpler effects can improve export speed.
• Quality-first can take much longer, but it gives weaker machines a better chance of a clean export.
• Short test exports are a good way to validate settings before a long render.

Updates & feedback

ImgTool.app is updated based on real usage and feedback. If something is confusing or you’ve got a practical feature request, email [email protected].

How content and tools are maintained

ImgTool.app is maintained as a practical toolset. Pages are written to explain what a tool actually does and what the current limits are.

The Music Visualizer is mainly tested as a desktop web app workflow in current versions of Chrome. When features change, the aim is to update the related guide and in-app wording. If you spot something broken, unclear, or out of date, please email [email protected].

Official channel

Demo exports, walkthroughs, and visualizer examples are published on the official ImgTool Music Visualizer YouTube channel.

Support ImgTool.app

If the visualizer saves you time or helps you publish faster, you can support ongoing work with a tip.

A note on “free”

The visualizer is free to start at 720p, with free HD exports still available under the support-watermark rules shown in the app and one free 4K test export per device. The 10-Day Release Pass unlocks clean HD/4K and the release-week tools, while the privacy-first, local-processing approach remains the goal.
