About Our Image Tools

Image editing has traditionally required expensive desktop software. Helium Dock changes that with a comprehensive suite of free, browser-based image tools that handle everything from basic resizing to advanced effects — without uploading your images to any server. Our image tools use the HTML5 Canvas API to process images entirely on your device. This means your photos stay private, processing is instant, and there is nothing to install. Whether you need to resize a product photo, compress images for your website, or apply creative filters, you will find the right tool here.

Frequently Asked Questions

Do my images get uploaded to your servers?
No. All image processing uses the HTML5 Canvas API and happens entirely in your browser. Your images never leave your device.
What image formats are supported?
Most tools support JPEG, PNG, WebP and GIF. SVG tools are also available for vector graphics.
Is there a file size limit for images?
There is no hard limit, but very large images may take longer to process depending on your device's memory and processing power.
