Step 1 : Upload image files

Upload the image files you would like to compress.

Step 2 : Process files using browser image compression

The uploaded images are fed to the browser-image-compression module which processes them and returns the compressed images.

Step 3 : Download Compressed Images

Here at BlockSurvey, we give at most importance to privacy which is consistent with our vision of a world having a decentralized internet space.

How does image compression tool work?

The tool reads the data from the HTML file reader API and uses the browser-image-compression module to process it. The browser-image-compression module creates an HTML canvas element and draws the image on it and gets the scaled down data back from the canvas. The returned dataURI is read, decoded from Base64 and displayed to the user.
