How to edit a PDF in your browser

  1. Drop a PDF into the editor. Rendering, text extraction, editing and saving all happen inside your browser — the document is never uploaded.
  2. Switch to Edit text and click a line. Every detected line lights up. Type the replacement: the original glyphs are covered with a patch sampled from the page’s own background colour, and your text is redrawn at the same baseline, size and colour. Correct the font, size or colours in the right panel if the automatic detection needs help.
  3. Set the page plan in the left rail. Rotate, duplicate, move, delete and insert blank pages; the export follows that order. Pages are copied at the object level rather than re-rendered, so a 300 dpi scan is still 300 dpi, and annotations travel with their page.
  4. Fill forms, annotate, sign or cover content. Interactive AcroForm fields appear as real inputs in the right panel. The Erase tool covers content with an opaque patch, the Draw tool adds a handwritten signature, and shapes, highlights and images go on top.
  5. Press Download edited PDF. The file is written on your own machine. Tick “Flatten form on export” first if the field values should become permanent page content.

How editing existing text works

A PDF does not contain paragraphs. It contains instructions to draw specific glyphs at specific coordinates, which is why no editor can simply retype a sentence and reflow the rest. What a real editor does — including this one — is three precise steps: locate the glyph run and its exact box, paint over it with the page's own background colour, and redraw the replacement at the same baseline, size and colour.

Switch to Edit text and every detected line lights up. Click one, type the replacement, and adjust the font, size, colour or patch colour in the right panel if the automatic detection needs help. The rest of the page is untouched: text elsewhere stays selectable, vector art stays vector.

Page structure, in the same tool

The page rail is not a preview — it is the page plan for the exported document. Rotate, duplicate, move, delete and insert blank pages there, and the export follows that order. Pages are copied at the object level rather than re-rendered, so a 300 dpi scan is still 300 dpi afterwards. Your annotations travel with their page when it moves.

Forms are filled, not faked

When the document carries an interactive AcroForm, its fields appear as real inputs in the right panel — text fields, checkboxes, radio groups and dropdowns, with their current values pre-loaded. Fill them and export; tick flatten if the values should become permanent page content that no one can change back.

Redaction: what covering does and does not do

The Erase tool covers content with an opaque patch, sampled from the surrounding page so it blends in. That is correct for fixing a typo or hiding a figure in a screenshot, and it is not sufficient for legal redaction: the covered text may still exist in the file underneath. For irreversible removal, export the pages with PDF to PNG and rebuild the document from images using PNG to PDF — that discards everything not visible.

A visible signature is not a digital certificate

Drawing your signature, or placing a PNG of it, produces the same visible mark as signing with a pen. Neither creates a certificate-backed digital signature with identity validation. If a regulated workflow demands cryptographic signing, use the system the recipient specifies.

Keyboard shortcuts

Ctrl/⌘ + Z undo, Ctrl/⌘ + Shift + Z redo, Delete removes the selected object, Esc clears the selection and returns to the Select tool.

Frequently asked questions

Can I really edit the text that is already in the PDF?

Yes. Switch to the Edit text tool and every line of text on the page becomes clickable. Click one and you can rewrite it: the original glyphs are covered with a patch sampled from the page’s own background colour, and your replacement is drawn in the detected font size and colour. That is the same technique desktop editors use, because PDF stores positioned glyphs rather than editable paragraphs.

Does editing rasterise the page or destroy the rest of the text?

No. The page keeps its original content stream: text elsewhere stays selectable and searchable, vector art stays vector, and images keep their resolution. Only the specific line you replaced is painted over.

Can I reorder, rotate or delete pages?

Yes — the page rail on the left rotates, duplicates, moves, deletes and inserts blank pages. Pages are copied rather than re-rendered, so nothing loses quality, and your annotations follow their page when it moves.

Can I fill in a PDF form?

If the document has an interactive AcroForm, its fields appear in the right-hand panel as real inputs, checkboxes and dropdowns. You can fill them and optionally flatten the form on export so the values become permanent page content.

How do I black out confidential information?

Use the Erase tool with a black patch colour to cover it. Be aware of the limit: this covers the content visually and is enough for print or screen sharing, but the original text may still exist underneath in the file. For legally binding redaction, export the page as an image with PDF to PNG and rebuild the document from the images.

Is my PDF uploaded while I edit it?

No. Rendering, text extraction, editing and saving all happen inside your browser. Neither the source document nor the edited result leaves your device — verifiable in your browser’s network tab.

Can I sign a PDF here?

You can draw a handwritten signature with the Draw tool or place a PNG signature image. That is a visible signature, the equivalent of signing with a pen — not a certificate-backed cryptographic signature.

Can I edit a password-protected PDF?

A PDF encrypted with an open password must be unlocked first. The editor deliberately does not bypass document encryption.
