Private & Secure Image Comparison
BeforeAfterly is a privacy-focused before/after image slider that processes everything locally in your browser. No sign-up required, no image uploads to servers. Your photos stay completely private on your device—perfect for confidential client work, personal transformations, or sensitive property photos.
All image processing happens client-side using modern web technologies. The only network requests are for analytics and optional ads; your actual image data never touches our servers. Delete comparisons anytime, and all temporary previews are automatically cleared when you close the browser.

Frequently Asked Questions
Everything you need to know about our image comparison tool
❓Do you upload my images anywhere?▼
No. Images stay in memory inside your browser and are only referenced through short-lived local links that disappear when you leave.
📸What files work best?▼
PNG, JPG, and WEBP up to the limits of your device. Higher resolution images may take longer to preview but still never leave your computer.
💼Can I use it for client presentations?▼
Yes. Use autoplay for hands-free demos, or export a screen recording of the slider animation.
