PDF Toolkit

A complete set of PDF operations that run entirely inside your browser. Merge documents, extract page ranges, rotate pages, convert between PDF, Word and Excel, and place text or whiteout boxes on a page — without any file being uploaded to a server.

Why local processing matters here

Most free online PDF tools work by uploading your document, processing it on their infrastructure, and sending back a result. For a restaurant menu that is unremarkable. For an employment contract, a bank statement, a medical letter or a signed agreement, it means handing a complete copy to a company you know nothing about. Every operation in this toolkit runs locally using the browser's own capabilities. Your file is read into memory, transformed, and offered back as a download. Nothing is transmitted, which is why it works even with your connection disabled after the page has loaded.

Merging and page ranges

Merging appends documents in the order they are listed, which is worth checking before you run it: files are usually listed alphabetically by filename rather than in the order you intend. Use the arrows to reorder first. Page ranges accept a compact notation — 1-3, 5, 8-10 selects pages one through three, five, and eight through ten. Ranges are inclusive at both ends, so 1-3 yields three pages. One subtlety catches people out: page numbers refer to the physical position in the file, not the number printed on the page. A report with three cover pages before printed page 1 means that page is physically page 4.

Conversion, and what it can realistically do

PDF to Word reads the text layer embedded in the document and rebuilds it as an editable file, detecting headings from font size and tables from column alignment. This works well for digitally created PDFs. It produces nothing at all for scans, because a scanned page is an image and contains no text to extract — that requires OCR, a different technology. Word to PDF carries across headings, paragraphs, bold and italic runs, lists and simple tables. Complex layouts, embedded images and precise styling are simplified. Only the modern .docx format is supported. Excel to PDF renders each worksheet as a table with a repeating header row, sized to fit the page. Formulas appear as their calculated values rather than the formula text.

Editing text, honestly

PDFs cannot be edited the way a word processor document can, and no browser tool can change that. Text in a PDF is stored as positioned glyphs drawn with embedded fonts rather than as editable sentences, so it cannot be re-flowed. What the Add Text and Whiteout tools do is place new content on top of the page. Cover an error with a white box and type the correction over it. That handles typos, form filling and dating a document, which covers most everyday needs. One important caution: a whiteout box hides content visually but the original text may remain extractable underneath. Never rely on it to redact confidential information. Genuine redaction means removing the content from the source document before the PDF is created.

Quick tips

• Password-protected PDFs must be unlocked before any tool can read them.
• Extract only the pages you need before converting — fewer pages, fewer things to go wrong.
• For heavy editing, convert to Word, edit there, and convert back.
• If a file refuses to load, opening and re-saving it in a PDF reader sometimes repairs the structure.

Are my PDF files uploaded anywhere?

No. Every operation runs locally in your browser using the pdf-lib library. Your documents never touch a server, so this is safe for contracts, invoices, and confidential paperwork.

How do I specify which pages to extract?

Enter page numbers and ranges separated by commas, for example 1-3, 5, 8-10. Leave the field empty to apply the action to every page in the document.

Can it open password-protected PDFs?

No. Encrypted PDFs cannot be processed. Remove the password using the application that created the file, then run it through this tool.

Does merging reduce quality?

No. Pages are copied across at their original resolution and embedded fonts are preserved, so a merged document looks identical to its sources.

How good is PDF to Word conversion?

It reads the text layer embedded in the PDF and rebuilds it as an editable .docx, detecting headings from font sizes, paragraph breaks from spacing, and tables from column alignment. Text and simple tables come across well, but exact page layout and images are not reproduced. It cannot read scanned PDFs, which are images of text and contain no text layer.

How does table detection work, and why did it get one wrong?

A PDF stores no table structure, so tables are inferred from column alignment: when consecutive lines start text at the same horizontal positions, that is treated as a table. This works well for ordinary tables, but a genuine two-column page layout looks identical to a two-column table, so it can occasionally be misread. Untick the Detect tables option to get plain text instead.

Why did nothing come out of my scanned PDF?

A scan is a picture of a page, so there is no text to extract. Reading it requires OCR (optical character recognition), which is a different technology and is not part of this tool yet.

What carries over when converting Word to PDF?

Headings, paragraphs, bold and italic runs, bulleted and numbered lists, and simple tables are reproduced. Complex layouts, embedded images, headers and footers, and precise styling are simplified. Only .docx files are supported; save older .doc files as .docx first.

Can I edit the existing text inside a PDF?

Not directly, and no browser-based tool can do this reliably. Text in a PDF is stored as positioned glyphs using embedded fonts rather than as editable sentences, so it cannot be re-flowed. The Add Text and Whiteout tools let you cover the old content and type replacement text on top, which handles typo fixes and form filling. For heavy editing, convert to Word, edit there, and convert back.

Is a whiteout box safe for redacting confidential information?

No. A whiteout box hides content visually, but the original text may still exist underneath and could be selected or extracted. Do not rely on it to remove sensitive data. For true redaction, remove the content in the source document before creating the PDF.
