Why Choose Client-Side Processing?

Trim margins or crop specific areas of your PDF pages locally. Draw custom crop boxes on page canvases and apply adjustments instantly.

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.
