Online PDF Tools: Free Merge, Split, Compress and Convert

Kwebby's online PDF tools let you merge, split, rotate, compress, watermark, encrypt and convert PDF files without installing software. The hub lists 28 tools in five groups. The PDF tools process files in your browser without uploading them, and the four OCR tools send your image to Kwebby's server to read the text. Pick the tool that matches your task below, run it on a copy of your file and download the result. This page also shows how to chain tools for common jobs and how to keep your documents safe.

Key Takeaways

• Kwebby groups its PDF tools into five sets: Organize, Edit and Secure, Convert to PDF, Convert from PDF, and Extract and OCR.
• The PDF tools process files in your browser with no upload. The OCR tools (JPG, PNG, BMP and TIFF to Text) send the image to Kwebby's server and an AI provider, so keep sensitive scans out of them.
• Start with Merge PDF, Split PDF and Compress PDF, which cover most everyday jobs.
• PDF to Word and PDF to PowerPoint extract text only, so they will not rebuild a complex layout.
• Word to PDF, Excel to PDF, HTML to PDF and URL to PDF finish in your browser's print dialog, where you choose Save as PDF.
• Work on copies, scan any downloaded file, and use a strong password if you encrypt a PDF.

What Kwebby's PDF Tools Do

Every tool does one job on one file type, and you can chain them. The five groups below map to the sections of the hub. If you are not sure where to begin, the All-in-One PDF Converter detects your file type automatically and converts it.

PDF stands for Portable Document Format, and Adobe says it is now an open standard maintained by the International Organization for Standardization (ISO). That is why one file looks the same on any device, and why so many tools can read it.

Organize: Merge, Split, Rotate and Compress

These four tools change how a PDF is arranged or how large it is.

• Merge PDF: Combine several PDFs into one file and set the order with the arrow buttons.
• Split PDF: Break a PDF into single pages or custom page ranges, and download each section.
• Rotate PDF: Turn pages by 90, 180 or 270 degrees, for all pages or a chosen range.
• Compress PDF: Reduce file size and compare the before and after sizes. Results vary by file.

Edit and Secure: Watermark and Encrypt

• Watermark PDF: Add a text watermark to every page and set the text, opacity, angle and color.
• Encrypt PDF: Add a password so only people who know it can open the file.
• Decrypt PDF: Remove a password you know, plus the printing, copying and editing limits.

A password keeps casual readers out. It does not make a file safe to send to the wrong person, so choose a long, unique password and share it through a different channel than the file.

Convert Files to PDF

Use these tools when you start with another format and need a PDF.

• JPG / Image to PDF: Turn JPG, PNG, WebP, GIF or BMP images into a PDF, pick the page size and reorder the images.
• PNG to PDF: Turn PNG screenshots and graphics into a PDF without loss, with transparency kept.
• TXT to PDF: Convert plain text and set the font size and margins.
• Word to PDF: Convert .docx files, preview them and save through the print dialog.
• Excel to PDF: Convert .xlsx, .xls, .csv and .ods files, with every sheet drawn as a table.
• PowerPoint to PDF: Turn the text of a .pptx presentation into a PDF, one page per slide. Designs and images are not kept.
• HTML to PDF: Upload an .html file or paste code, then save it as a PDF.
• URL to PDF: Preview a webpage and save it with the print dialog.
• EPUB to PDF: Extract the text of an ebook into a downloadable PDF.
• CHM to PDF: Convert Windows CHM help files.

Convert From PDF

• PDF to Text: Extract all text, then copy it or download a .txt file.
• PDF to JPG: Export each page as its own JPG image.
• PDF to PNG: Export each page as a lossless PNG image, best for text, charts and diagrams.
• PDF to Word: Extract the text into a .docx or .txt file. Layout, images and tables are not kept.
• PDF to PowerPoint: Extract slide text from a PDF presentation as a .txt file.
• PDF to HTML: Wrap the text of each page in styled HTML and download an .html file.

Extract Images and Text With OCR

OCR means optical character recognition, which reads text out of a picture. Use these when your text sits inside an image or a scan. The OCR tools prepare the image in your browser, then send it to Kwebby's server, which passes it to an AI model to read the text. Kwebby does not store the image.

• Extract PDF Images: Save each page as a PNG image, skip blank pages and crop the parts you need.
• JPG to Text (OCR): Read text from JPG and JPEG images.
• PNG to Text (OCR): Read text from PNG screenshots.
• BMP to Text (OCR): Read text from BMP bitmap images.
• TIFF to Text (OCR): Read text from scanned TIFF documents.

Which PDF Tool Should You Use?

Match the tool to the job, then chain a second tool if needed.

1. The file is too large to email: Run Compress PDF and compare the sizes. If it is still large, split it with Split PDF and send the parts.
2. You need one file from many: Combine documents with Merge PDF, then rotate any sideways pages with Rotate PDF.
3. You have photos of a document: Use JPG / Image to PDF, put the pages in order and compress the result.
4. You need text from a scan: Try an OCR tool, such as JPG to Text, then paste the text into a document. Check the result against the original, because OCR can misread small or blurry print.
5. You want to extract only part of a file: Use Split PDF to save the pages you need.

Privacy and Safety With PDF Tools

PDFs often hold contracts, IDs and invoices, so treat every upload with care. Kwebby's PDF tools, from Merge PDF to PDF to PNG, process files in your browser and do not upload them. The OCR tools are the exception: they send the image to Kwebby's server and an AI provider to read the text. Other sites work differently. For example, PDF24 states that its online tools process files on its servers, so always read how a site handles files.

Fake converter sites are a real risk. In March 2025, the FBI's Denver office warned that criminals use free online converters to spread malware. Keep your antivirus up to date, scan downloaded files and stick to sites you recognize. Never put a passport number or bank details into a tool that does not need them.

Tips for Better Results

• Work on copies. Compression and conversion can change a file in ways you cannot undo.
• Check the output. Open the new file and scroll through every page before you send it.
• Expect plain text from text extractors. PDF to Word and PDF to PowerPoint extract text, so fonts, tables and layouts may change.
• Pair PDFs with other Kwebby tools. Shrink images first with the Image Optimizer, count words with Word Counter Pro or explore the Text Tools and Image Tools hubs. Developers can browse the Developer Tools.

Final Thoughts

The right PDF tool is the one that fits your task, handles your file the way you accept and gives output you can check. Start with Merge PDF, Split PDF or Compress PDF, test with a sample file and chain a second tool if you need one. For more free utilities, return to the All Tools directory.
