PDFs are the universal format for sharing documents — but working with them has traditionally required expensive software. Today, a suite of free online tools handles every common PDF task directly in your browser.
The Complete Free PDF Toolkit
Converting PDFs
PDF to Word — Convert any PDF to an editable .docx file. Preserves formatting, tables, and layout. Essential when you receive a PDF that needs editing.
Word to PDF — Convert .docx or .doc files to PDF. Ensures the document looks identical on every device and operating system.
PDF to JPG — Convert each page of a PDF to a JPG image. Useful for sharing individual pages, creating previews, or uploading to platforms that only accept images.
Reducing PDF File Size
Compress PDF — Reduce PDF file size by up to 80% with no visible quality loss. Essential for emailing large PDFs, uploading to document portals, and reducing storage.
Combining and Splitting PDFs
Merge PDF — Combine multiple PDF files into one. Perfect for assembling reports, combining scanned documents, or packaging a proposal with supporting attachments.
Split PDF — Extract specific pages or divide a PDF into multiple smaller files. Share only the relevant section rather than an entire 100-page report.
Rotating and Fixing PDFs
Rotate PDF — Fix sideways or upside-down PDF pages. Essential for scanned documents that were fed into the scanner at the wrong angle.
Security
Protect PDF — Add a 256-bit AES password to a PDF. Restrict access to sensitive documents — financial records, contracts, confidential reports.
Unlock PDF — Remove the password from a PDF you already have access to. Makes it easy to merge, compress, or convert the document without re-entering the password each time.
Signing
Sign PDF — Add an electronic signature to any PDF. Draw, type, or upload your signature. Legally valid for most business documents.

Tips for Working with PDFs Efficiently
Convert for editing, convert back for sharing. The ideal workflow for editing a received PDF: convert to Word → edit → save as PDF again. Editing in Word preserves formatting far better than editing in PDF software.
Compress before emailing. Most email providers have a 25 MB attachment limit. Running a PDF through the compressor before attaching often eliminates size-limit errors.
Protect before sending sensitive documents. Any PDF containing financial data, personal identification, medical records, or confidential business information should be password-protected before sending via email.
Merge supporting documents. Instead of sending 6 separate PDF attachments, merge them into one organised document. Easier for the recipient to file, read, and reference.
Unlock before processing. If a received PDF is password-protected and you need to compress, merge, or convert it, unlock it first to allow the other tools to process it.
PDF Quality Checklist
Before sending any important PDF: - [ ] Does it open correctly and display the intended content? - [ ] Is the file size appropriate for email (under 25 MB)? - [ ] Are all pages in the correct orientation? - [ ] Has sensitive content been password-protected? - [ ] Are all attachments/supporting documents merged if relevant?
Frequently Asked Questions
Do I need Adobe Acrobat for PDF work? No. For standard operations — converting, compressing, merging, splitting, rotating, protecting, unlocking — free online tools like iConvertU handle everything Adobe Acrobat Pro does, at no cost.
Are these tools safe for confidential documents? iConvertU processes files on secure servers and deletes them within 20 minutes. For highly sensitive documents (legal, medical, financial), you may prefer to use desktop software that processes files locally.
Can I use these tools on a phone? Yes. All iConvertU PDF tools are fully functional on iPhone and Android. Upload from your Files app, process, and download directly to your device.
Is there a file size limit? Free users can process files up to the free plan limit. For large PDF files, a Pro account increases the limit significantly.
