How Browser Processing Works
Decode images and PDFs locally with Canvas and WebAssembly.
What happens on your device
You pick a file and the browser reads it into memory.
Decoders (sometimes WebAssembly) turn bytes into pixels or PDF pages.
Encoders rebuild the output file for download.
Why it matters
No desktop install for quick tasks.
Privacy improves because the file does not leave your device during processing.
Frequently asked questions
Do I need an internet connection?
To load the page yes; afterward many tools process files without sending them remotely.
