Built for Privacy and Speed

Every day, millions of people upload their personal photos and business images to third-party servers just to perform simple conversions. That data is often stored, analyzed, or monetized — and users rarely know it's happening.

We built IMGVO to change that. By leveraging modern browser APIs (Canvas, WebAssembly, and the File System Access API), we can convert, compress, resize, and process images entirely on your device. No server ever sees your files. Not even ours.

The result is a tool that is not only more private — it's also faster. No upload time, no queue, no waiting for a server response. Your images are processed at the speed of your own hardware.

IMGVO uses a combination of the browser's native Canvas API for format conversion and resizing, WebAssembly modules for AVIF and advanced compression, and IndexedDB for locally-stored conversion history — none of which require a network connection after the initial page load.

Our compression algorithm adapts to each image's content. Photos with complex detail get different treatment than flat-color illustrations or screenshots. The goal is always the smallest file at the best perceptible quality.

We publish detailed guides about how image compression works, when to use JPG vs PNG, and the best image formats for web — because informed users make better decisions.

IMGVO publishes guides, comparisons, and tutorials about image formats and web performance. All of our editorial content follows a strict fact-checking and review process. We do not publish sponsored content disguised as editorial, and we do not receive payment to recommend specific tools or services.

Our guides are reviewed by technical contributors and updated whenever standards or browser support changes. Read our full Editorial Policy for details.
