A first-time tour of the basics. A quick tour of the main tools.
Drag a file straight onto the page, or click "Choose a PDF file." Nothing uploads — the file just loads into your browser's memory, the same way an image loads when you open one.
Click Add Text in the left toolrail, then click anywhere on the page to drop a text box. Type your value, drag the small handle to reposition it, drag the corner to resize. This works even on forms that were never made fillable — you're just writing directly onto the page.
Click Draw, then pick a shape from the dropdown — Freehand, Line, Arrow, Rectangle, Ellipse, Highlight, Redact, Eraser, or Signature. Click and drag over whatever you want to mark. Redact is genuinely permanent: applying it converts that page into a flat image, so the underlying text is actually gone, not just covered. Signature works differently — type your name once and pick from four cursive styles.
Click Form, choose a field type — text, checkbox, radio button, dropdown, date, number — and click on the page to place it. Drag the small handle to move it, the corner to resize. Check "Keep as a fillable form" in the panel if you want it fillable later — otherwise your typed values get baked in as flat text.
Click Merge, add the files you want combined, drag to reorder them, then merge. Useful for assembling a denial letter, the original claim, and supporting documents into one file.
Click Split to break a multi-page PDF into separate files — by page range, or one file per page.
Click Download PDF (top right) any time. Every edit — text, drawings, form fields — gets baked in automatically before the file downloads. There's also a Print icon right next to it if you just need a hard copy.
Open multiple PDFs at once using the tabs at the top. Switching between them is just normal tab switching — nothing in one affects the others.
