Frequently asked questions
Is Fill PDF Form free?
Yes — completely free, with no signup and no watermarks. PL Tools is supported by a small number of non-intrusive ads.
Are my files uploaded anywhere?
No. Fill PDF Form runs entirely in your browser, so your files never leave your device and are never sent to our servers.
Is there a file size limit?
Nothing is uploaded, so there's no upload limit — but very large files depend on your device's memory. Files up to about 100 MB work well on most computers; phones may struggle with much larger ones.
Does it work with any PDF form?
Fillable PDFs (with form fields) show every field in a panel — type answers, tick boxes and pick options. For scanned or flat forms, use Add text, Tick mark and Date to write on the page. XFA forms (a rare older format) aren't supported.
What does “Flatten” do?
It turns your answers into part of the page, so the form can't be changed afterwards and looks the same in every PDF reader.
Which formats are supported?
Input: Fillable or flat PDF form. Output: Filled PDF (optionally flattened).
Does it work on my phone?
Yes. PL Tools works in any modern browser on iPhone, Android, tablets and desktop — there's nothing to install.
