Edit PDF Files Online
Editing a PDF can mean several very different jobs. Sometimes you only need to rotate a sideways scan; sometimes you want page numbers, a watermark, a tighter crop, fillable fields, or an annotation layer. This category separates those jobs into focused tools so the interface stays understandable and each output can be validated before download.

The interface is designed to keep the active PDF workflow near the top of the page, while this guide explains what the tool changes, what it preserves, and where a different PDF tool is the safer choice.
Add Content to PDF Pages
The visual editor adds new text, images, drawing strokes, highlights and shapes on top of existing PDF content. Source pages remain PDF pages instead of screenshots. This is useful for notes, labels, callouts, stamps and simple document corrections where replacing the underlying original text is not required.

Rotate PDF Pages
Rotation changes the actual page rotation property rather than applying a browser-only CSS transform. Existing page rotation is considered, so rotating a page that already has a 90-degree setting produces the expected normalized final orientation.

Number PDF Pages
Page numbering can begin on any selected source page while the displayed number starts from a custom integer. Positions are calculated independently for each page size, allowing mixed portrait and landscape documents to be numbered without forcing every page into one geometry.

Add Watermarks
Text and image watermarks are added as real PDF overlays. Users can control opacity, rotation, location and page selection. Repeated watermarks are supported with bounded tiling so the tool does not create thousands of unnecessary overlay objects.

Crop PDF Margins
The crop tool changes the PDF CropBox by default, preserving the original page content and vectors. Cropping changes what viewers display but should never be treated as secure redaction because content outside the crop region may remain inside the file.

Create and Fill PDF Forms
The Forms tool works with standard AcroForm fields. Existing text fields, checkboxes, radio groups, dropdowns and list boxes can be filled where supported, while new interactive fields can be created. XFA forms are a different technology and are not advertised as supported.

Why Browser-Based PDF Editing Is Useful
Client-side processing avoids sending document bytes, form values, added text or watermark content to a conversion server. It also makes the category deployable as static files. Browser memory and device capability still matter for very large or highly complex files, so long-document rendering is handled progressively where practical.

Frequently Asked Questions
What is the Edit PDF category?

Are files uploaded?
No. The tools are designed for local browser processing.
Can I edit existing text?
The visual editor adds content and annotations; arbitrary existing text is not promised as directly editable.
Is cropping redaction?
No. CropBox cropping only changes the visible area.
Are forms real PDF fields?
The Forms tool uses standard AcroForm operations.
Does editing affect signatures?
It can invalidate existing digital signatures.
