What is Edit PDF?
Edit PDF adds new text, JPG or PNG images, and colored rectangles on top of existing pages. It is an overlay editor: it does not rewrite, delete, reflow, or directly modify existing PDF text.
You navigate to a page, click its preview to choose a placement point, configure an overlay, and add it to a pending edit list before downloading.
Why Use This Tool?
Overlays are useful for adding a short note, label, image, highlight block, or simple visual annotation. Multiple edits can be placed across different pages in one session.
This is not a full document-layout editor. Existing content remains underneath, and a rectangle is only a visual overlay rather than secure redaction.
- Add a text label in a chosen color and size.
- Place a JPG or PNG at a relative page width.
- Draw a rectangle with chosen size, color, and opacity.
How Does This Tool Work?
The preview records the clicked location as percentages of page width and height. Text uses Helvetica with a 10–72 point size. Images preserve aspect ratio and can use 5%–80% of page width. Rectangles support configurable proportional width, height, color, and opacity.
Added overlays appear in a list and may be removed before saving. On download, each overlay is drawn onto its assigned PDF page. The preview markers indicate placement but are not full renderings of final overlay dimensions.
Understanding Your Results
The output contains the original pages plus the new drawn content. Verify the downloaded file because a placement near an edge may extend beyond the visible page, especially for wide images or rectangles.
Text placement is constrained horizontally where possible, while image and rectangle positions are based directly on the selected ratios. The editor requires at least one added edit.
Why Tracking This Matters
A focused overlay tool can handle small additions without recreating an entire PDF. Its limitations are equally important: covering content does not remove that content from the underlying PDF.
For confidential information, do not assume an opaque shape is secure redaction. Use a process that removes underlying content when that requirement applies.
Benefits of Using Edit PDF
- Supports text, image, and rectangle overlays.
- Places edits on any page through a preview.
- Maintains a removable edit list before save.
- Processes and saves locally in the browser.
How Is the Result Calculated?
Placement and shape dimensions are stored as fractions of each target page, allowing them to scale with that page's width and height.
Drawn width = page width × selected width percentage
- Selected width percentage
- Image or rectangle width as a fraction of the page.
Tips for Better Results
- Click the preview before adding each edit.
- Check the target page number.
- Keep overlays away from page edges.
- Review the final download at normal zoom.
- Never use a rectangle as guaranteed secure redaction.
Conclusion
Edit PDF is built for straightforward overlays rather than rewriting a document. Place and review each addition carefully, and use a true content-removal workflow for sensitive redaction.
