Why Choose Client-Side Processing?
Optimize PNG image sizes locally in the browser. Retains transparent background channels while reducing storage size.
Instead of standard web servers converting, rewriting, or holding files in cache, TellPDF mounts WASM binaries directly in your browser. All memory registers are local and vanish once you reload the page.
