Conversion without the upload.

Traditional converters send your image to a remote server, wait for processing, then send a new file back. FormatSprout skips that round trip.

1. Your browser reads the image

Modern browser APIs decode the selected JPG, PNG, or WebP file in local memory. The file never becomes an HTTP upload.

2. A fresh image is rendered

The image is drawn onto a temporary browser canvas at the requested dimensions. JPG exports receive a white background; PNG and WebP can keep transparency.

3. The browser exports your result

The canvas creates a new file in your chosen format. This also strips embedded EXIF metadata. FormatSprout creates a temporary download link and releases it when no longer needed.

Compatibility and limits

A current version of Chrome, Edge, Firefox, or Safari is recommended. Animated files are converted from a single still frame. Each input is limited to 50 MB and decoded images to 40 megapixels to protect device memory.
