Frequently Asked Questions
What image formats are supported for before/after sliders?
The tool supports all common web image formats including JPEG, PNG, WebP, and GIF. Images are automatically optimized and converted to data URLs for seamless integration into the generated HTML code. For best results, use high-quality images with similar dimensions and lighting conditions.
Can I customize the appearance of the slider handle and divider?
Yes, you can customize the handle color (white, black, blue, red, green), divider width (2-8 pixels), and initial position (10-90%). The generated code includes all styling inline, making it easy to further customize colors, shadows, and effects by editing the CSS in the exported code.
Is the generated slider responsive and mobile-friendly?
The generated slider code includes responsive CSS that adapts to different screen sizes. On mobile devices, the slider uses touch events for smooth dragging interaction. The container maintains its aspect ratio while scaling appropriately for smaller screens.
How do I integrate the generated slider into my website?
Simply copy the complete HTML code and paste it into your webpage. The code is self-contained with embedded images, CSS styles, and JavaScript functionality. No external dependencies or additional files are required. You can also save the code as an HTML file for standalone use.
What happens to my uploaded images?
All image processing happens locally in your browser using JavaScript Canvas API. Your images are never uploaded to any server and are converted to embedded data URLs in the final code. This ensures complete privacy while creating a portable, self-contained slider that works without external image files.
