Need to complete a form? Use the PDF Form Editor to fill interactive fields and add text locally.
Choose the right way to make or edit a PDF
To make a PDF from photos or scanned pages, use JPG to PDF. To turn plain typed content into a simple document, use Text to PDF. These focused tools create new PDF files from different source material.
The PDF Form Editor fills existing interactive fields and can place text on a page. It does not create new fillable form fields. ToolZone does not currently add a watermark directly to a PDF, so do not use these pages when a PDF watermark or a new form-field layout is required.
PDF to DOCX needs document reconstruction
ToolZone does not currently export a PDF as an editable DOCX or promise to preserve its layout in Word. A PDF stores positioned page content, while DOCX stores editable document structure; scanned pages also need OCR. Converting between them can change columns, tables, fonts, images, forms, headers, footnotes, and reading order.
For a permitted scan, convert the required pages with PDF to JPG, run the images through Image to Text OCR, and paste the reviewed text into a document manually. Use specialist conversion software when layout fidelity matters.
How to Use Free PDF Merger and Splitter
Free PDF Merger and Splitter helps combine or separate real PDF files while keeping page order and document meaning clear.
- Choose the actual PDF files and check their order before merging or splitting pages.
- Decide whether the task is one combined PDF or selected page ranges before exporting.
- Process a small set first when documents are large, then confirm the page sequence before sharing.
- Missing pages, wrong order, or mixed document versions can create a PDF that looks valid but says the wrong thing.
- Name the rebuilt PDF with its page range, source set, or purpose so it is easy to verify later.
Things to Check
- Encrypted pdfs or unusual forms may fail.
- Large multi-page PDFs and big merge batches can use heavy browser memory; split the job on low-memory devices.
- Review the PDF in a viewer, portal, or email draft where page order and readability matter.

Combine several PDF files into one document
Use Merge mode to arrange and combine permitted local PDF files. For JPG or PNG images, use the Image to PDF Converter. For Word files, export each document to PDF in the original editor before merging so page layout can be reviewed.
The merger does not convert DOCX, repair corrupt PDFs, preserve every interactive form or signature workflow, perform OCR, or combine arbitrary mixed file types directly. Read How to Combine PDF Files for ordering and verification steps.
How to watermark a PDF file
To add a watermark to a PDF, open the PDF Tools page, select your file, choose a text or image watermark, adjust the position, opacity, and angle, then download the watermarked PDF. Common uses include marking drafts as "Confidential," branding documents before sharing, and overlaying copyright notices on client deliverables.
For photo-based documents, you can also blur or redact sensitive areas before watermarking using the Image Censor Tool. To watermark multiple pages at once, apply the same overlay to each page in the PDF before exporting. Read the PDF optimization guide for file-size tips after watermarking.
Rearrange and split PDF pages online
To rearrange PDF pages, upload the file, view the page thumbnails, drag pages to reorder them, and download the rearranged PDF. You can also delete unwanted pages, duplicate pages, or extract specific page ranges into a new file.
For splitting a PDF into separate files, select a page range for each output file and download individually. Common scenarios: extract pages 1-5 as an executive summary, separate appendices into standalone documents, or reorder chapters. Read the PDF optimization guide for file-size tips after rearranging.
