Honest scope: this is additive editing - existing PDF text cannot be modified or deleted; exports overlay additions onto the untouched original.
About this tool
A contract missing one supplementary line, a form field left blank, a key point to circle on a slide - none of these need the PDF rebuilt, just something added on top. Three lightweight tools cover it: text boxes (any font, size and color, CJK included), image inserts (PNG/JPG stamps, logos, screenshots) and freehand drawing with mouse or touch.
Editing is page-by-page with live preview: switch pages, click to add, drag to reposition, tweak size and color in the side panel - what you see is the page. On export, pdf-lib writes the additions as an overlay onto the original PDF; existing text, images and layout are untouched. This is not a rebuild - it is an overlay on the original.
Honest scope: this is "additive" editing - existing text cannot be rewritten (reflowing editors are beyond browser capability); use your reader’s form feature for form fields. Everything runs locally, files never upload.

Frequently asked questions
- Can it change text that already exists in the PDF?
- No. PDF text is the output of a typesetting engine; rewriting it means re-layout, which browsers cannot do faithfully. The tool’s job is additions; to change wording, edit the source document and re-export, or cover the old text with a white image and add new text on top.
- How is this different from the watermark tool?
- Watermarking is batch and regular: the same text at the same spot on every page. The editor is per-page and free-form - different text, images and drawings anywhere on any page. Use the watermark tool for stamping every page; use this for precise single-page edits.
- Does editing recompress the file or hurt quality?
- No. Export starts from the original PDF with additions written as vector text and standalone images; original page content is preserved byte-for-byte. Inserted images embed at their native resolution - crop them to size first to keep the file lean.
