Tool Guide

How to Add Text to a PDF Online

The Text tool lets you add text to PDF online free — type anywhere on a page, choose your font, size, and colour, then position the text box exactly where you need it.

1

Click the Text tool (or press T)

A colour picker popup appears first. Choose the colour for your text — this sets both the text colour and the box border colour.

2

Click anywhere on the PDF

A text box appears at that position. Start typing immediately.

3

Use the floating toolbar

While the text box is active, a small toolbar appears above it — Bold, Italic, Underline, font size (+/−), and text alignment buttons.

4

Choose your font from the toolbar

The font picker in the main toolbar lets you search and select from dozens of fonts — serif, sans-serif, monospace, handwriting and more.

5

Click outside to freeze & drag

Click outside the text box to freeze it. In Select mode you can then drag it anywhere on the page.

Tool Guide

How to Highlight PDF Content Online

The Highlight tool draws a semi-transparent coloured rectangle over any area of the PDF — perfect for emphasising important sentences or marking review notes. This is a key feature of any good pdf editor free online.

1

Press H or click Highlight in the toolbar

The cursor changes to a crosshair.

2

Choose your highlight colour

Pick any colour from the palette in the right panel. Yellow, green, pink, and blue are popular choices.

3

Click and drag across the text

A highlight box is drawn wherever you drag. Release to place it. Adjust opacity with the Opacity slider in the right panel.

Lower the Opacity slider (right panel) if your highlight colour is too strong — around 30–50% is usually ideal for reading through the highlight.

Tool Guide

How to Draw on a PDF Online — Freehand

The Draw tool gives you a freehand pen to draw on PDF online — circle items, underline text manually, sketch diagrams, or sign your name. It's the most flexible annotation tool in the editor.

1

Press D or click Draw

The canvas cursor becomes a crosshair.

2

Set stroke colour and width

Choose a colour from the palette in the right panel. Adjust the Border px slider to make your line thicker or thinner.

3

Click and drag to draw

Hold and drag on the PDF to draw smooth freehand strokes. Each stroke is stored separately so you can undo individual lines.

Signing PDFs: Use the Draw tool with a fine stroke width (2–3px) to handwrite your signature directly onto the PDF. This is the easiest way to esign pdf online free without any extra tools.

Freehand drawings are stored per-page. Switching pages or undoing with Ctrl+Z will remove the most recent stroke.

Tool Guide

Draw Shapes — Rectangles & Circles

Use the Rect and Circle tools to draw precise geometric shapes on your PDF — ideal for callout boxes, circling errors, or drawing attention to specific areas.

Rectangle Tool R

Click and drag on the PDF to draw a rectangle. You can control fill colour, border colour, border width, and opacity all from the right panel. Toggle No Fill to draw just an outline box.

Circle Tool C

Works identically to the Rectangle tool but draws an ellipse. Perfect for circling important words, figures, or sections that need review.

Tool Guide

How to Insert Images into a PDF

The Image tool (I) lets you insert PNG, JPG, WebP, GIF, or SVG images directly onto any PDF page. This is great for adding logos, stamps, photos, or signatures.

1

Click the Image button or press I

A file picker opens. Select your image (PNG, JPG, WebP, GIF, or SVG).

2

Image is placed on the page

The image appears in the centre of the PDF. It's selected automatically.

3

Drag to reposition

In Select mode, drag the image to the desired location on the page.

4

Resize by dragging the corner handle

A resize handle appears in the bottom-right corner of the image. Drag it to scale the image up or down.

Adding a signature: Take a photo of your handwritten signature on white paper, remove the background using any free tool, then use the Image tool to place the transparent PNG signature directly onto the PDF signature line.

Panel Guide

Colors & Style Panel — Full Guide

The right-side Properties Panel is your command centre for controlling how annotations look. Here's everything it contains:

Fill & Stroke Swatches

Two large swatches sit at the top — Fill (interior colour of shapes and highlights) and Border (outline colour). Click either swatch to open a colour picker. The No Fill button (⊘) makes the interior transparent.

Colour Palette

A grid of 24 preset colours is shown below the swatches — click any dot to apply it to the active swatch (Fill or Border, whichever was last clicked). The dot gets a white ring when selected.

Custom Colour

Use the full colour picker input to select any hex colour. Press F to apply it as Fill or S to apply it as Stroke/Border.

Border Width

A slider from 0–20px controls how thick the border/stroke of shapes and freehand drawings is.

Opacity

A slider from 10–100% controls the transparency of the annotation. Very useful for highlights — set to 30–50% for a subtle look.

Font Size

A number input (8–72px) controls the font size for text annotations.

Changes to the panel apply to future annotations. To change an existing annotation's colour, first select it with the Select tool, then update the panel values.

Panel Guide
