Why use this tool
Every PDF task, one place
Merge, split, compress, convert, sign, and more — no need to juggle separate apps for each job.
Private by default
Most tools process your file entirely in the browser — it's never uploaded. When a conversion needs the server, the file is deleted within the hour.
Works on any device
Runs in the browser on Windows, Mac, Linux, iOS, and Android — nothing to install, nothing to trust but the tab.
Fast by design
No queues and no desktop app to wait on — most jobs finish in a few seconds, right where you are.
Convert to and from any format
Move between PDF, Word, Excel, PowerPoint, images, and HTML — output stays true to your original formatting.
Free, always
Every tool here is free to use, with no watermarks, page limits, or forced trial period.
Frequently asked questions
This utility is specifically designed to interact with pre-defined fillable form fields (text boxes, checkboxes, dropdowns).
If the creator did not define a form field in that location, you cannot type there. The document is likely flattened.
You must download the partially filled file to your computer; the browser session will not remember your entries if reloaded.
By default, the output remains an interactive form. You must use the Flatten tool if you want to lock the answers permanently.
No, it respects the formatting rules (like requiring numbers or specific date formats) set by the original document author.
