File Picker
Transformation UI
Transform local file
Stop cleaning up user-submitted images on your backend. Let your users crop, resize, and apply filters in the browser before the file ever hits your server.
Transformation UI Customization
White-label Filestack’s image transformation UI to match your brand. Customize language, available tools, filter options, and output settings through simple configuration objects.
Events
Hook into image transformation lifecycle events to build custom workflows and UI feedback. Listen for crop, rotate, filter, and adjustment events in real-time, then trigger your own logic.
Document Viewer
Preview and page through documents inside your application. Both modes are a processing task in the file URL.
Document Mode
Don’t build your own document viewer. Let users preview files inside your application instead of forcing a download. Our viewer handles PDFs and automatically converts formats like DOCX and PPT on the fly.
Slideshow
Why just preview a document? Let users flip through it. Our viewer can turn any multi-page PDF or presentation file into a simple slideshow, right inside your app. No extra UI for you to build.
