Frequently Asked Questions

What is screenshot comparison and how does it work?

Screenshot comparison is a process that analyzes two images to identify visual differences. Our API uses advanced algorithms to detect discrepancies at the pixel level, allowing for precise visual diffs that can highlight changes in color, layout, or content.

How can I compare before and after website changes?

You can capture screenshots of your website before and after changes, then upload both images to our API. The service will generate a visual diff, highlighting any modifications with clear annotations, making it easy to assess the impact of your updates.

What is pixel-level detection in screenshot analysis?

Pixel-level detection refers to the ability of our API to identify differences at the most granular level — individual pixels. This ensures that even minor changes, such as color shifts or slight layout adjustments, are accurately flagged in the visual diff reports.

What formats do you support for screenshot uploads?

Our API supports multiple image formats, including PNG, JPEG, and BMP, with a maximum file size limit of 5 MB per upload. Response times for visual diff generation typically range from 2 to 5 seconds, depending on the image complexity.
