Step-by-step answers to practical tasks, each ending at the tool that does the job.
Test gift animations in Android, iOS, Flutter and web apps during a live call: dimensions, memory, lazy loading, queues, reduced motion and still fallbacks.
Shrink a JPG, PNG or WebP in your browser: pick the right format and quality, hit a target size for uploads, and avoid the mistakes that make images blurry.
Turn one or many JPG, PNG or WebP images into a single PDF for forms, applications and sharing: choose the page size, keep photos sharp, and keep the file small.
Combine several PDFs into a single file in your browser: put them in order, deal with password-protected files, keep text searchable, and avoid bloated output.
Pull selected pages out of a PDF, split every page into its own file, or remove a page from the middle, all in your browser using simple page ranges.
Plan an RTC gift integration from asset choice to validated events, client playback, duplicate handling and testing on mobile devices.
