Free Online PDF Tools — Convert, Merge, Split, Sign & More | TechPatraa
Do you open a different website every time you need to do something with a PDF? Convert it to an image on one site, merge two files on another, add a password somewhere else — and every time you worry about uploading your private documents to an unknown server.
TechPatraa's PDF Tools solves all of this in one place. 16 powerful PDF tools on a single page — completely free, no signup required, and most importantly, your files never leave your device. Everything runs inside your browser.
What Tools Are Included?
📄 PDF to Image
Convert every page of your PDF into high-quality JPG, PNG, or WebP images. Choose your quality level from 96 DPI up to 300 DPI. Download individual pages or all at once with a single click.
Best for: Sharing a PDF page on WhatsApp or social media, using a PDF page in a presentation, or creating thumbnails from a document.
🖼️ Image to PDF
Combine multiple JPG, PNG, or WebP images into a single PDF file. Drag and drop to reorder images before converting. Choose page size (A4, Letter, A3, or fit to image) and orientation.
Best for: Converting phone-clicked document photos into a PDF, submitting assignments, or sending multiple images as one file.
📎 Merge PDF
Combine two or more PDF files into one. Upload multiple files, drag to reorder them, then merge into a single clean PDF in seconds.
Best for: Combining office documents before sending, attaching certificates with a resume, or joining book chapters into one file.
✂️ Split PDF
Break a large PDF into smaller parts. Three modes available — extract every page as a separate file, split every N pages, or define custom page ranges like 1-3, 5, 7-9.
Best for: Extracting specific sections from a large report, sending only relevant pages to someone, or separating a combined document.
🔄 Rotate PDF
Rotate pages 90°, 180°, or 270°. Select individual pages or all pages at once. A visual thumbnail preview updates live so you always know what you are rotating.
Best for: Fixing upside-down or sideways scanned documents, correcting phone-scanned PDFs.
🗑️ Delete Pages
Remove unwanted pages from any PDF. Thumbnails of every page are shown — simply click the ones you want to delete. Use Select All, Deselect All, or Invert buttons for quick selection.
Best for: Removing blank pages from a scanned file, deleting confidential pages before sharing, or cleaning up a document.
💧 Add Watermark
Add a custom text watermark to your PDF. Control the position (8 options including diagonal and tile), color, font size, and opacity. Choose to apply it to all pages, only odd pages, only even pages, or just the first or last page. A live preview updates as you type.
Best for: Marking documents as CONFIDENTIAL, DRAFT, or SAMPLE before sharing, protecting work from unauthorized use.
📑 Extract Pages
Pick specific pages from a PDF and save them as a new file. Click thumbnails to select pages visually, or type a range like 1,3,5-8 and click Apply. All selected pages are combined into one new PDF.
Best for: Pulling out a specific chapter from a book, extracting only the relevant section of a large document.
🗜️ Compress PDF
Reduce the file size of any PDF. Four compression levels to choose from — Low for maximum compression (best for email and web), Medium for a balanced result, High for print-quality output, and Minimal for near-lossless compression. Shows before and after file size with percentage saved.
Best for: Fitting a PDF within an email attachment limit, sending large files over WhatsApp, or reducing storage usage.
🔀 Rearrange Pages
Drag and drop page thumbnails into any order you want. Use the Reverse Order button to flip the entire document instantly, or Reset to go back to the original order.
Best for: Fixing wrong scan order, reorganizing chapters, or reordering presentation slides saved as a PDF.
🔢 Add Page Numbers
Automatically add page numbers to every page of your PDF. Six position options (bottom center, bottom right, top left, etc.), four number formats (1 / Page 1 of 10 / -1- / 1/10), custom color, custom font size, and a choice of which pages to number. Live preview shows exactly how it will look.
Best for: Reports, thesis documents, legal papers, books, or any professional document that needs numbered pages.
✂️ Crop PDF
Trim the margins of your PDF by entering values in millimeters for Top, Bottom, Left, and Right. Six quick presets are available, or enter custom values manually. A live preview with a green crop box shows exactly what will be removed.
Best for: Removing extra white space from scanned documents, trimming oversized margins, or resizing page content.
🔒 Protect PDF
Add a password to your PDF using AES-256 encryption. Set a strong password (a live strength indicator guides you), confirm it, and choose what permissions to allow — printing, copying text, editing, and annotations. Compatible with Adobe Acrobat, Chrome, and all standard PDF readers.
Best for: Protecting salary slips, Aadhaar documents, legal agreements, marksheets, or any sensitive file before sharing.
🔓 Unlock PDF
Remove the password protection from a PDF you own. Enter the current password (or leave it blank for restriction-only PDFs), and the tool re-saves the file without any encryption. Also removes editing and printing restrictions.
Best for: Removing a forgotten password from your own PDF, unlocking a file to enable editing or printing.
🔍 OCR PDF
Extract text from scanned or image-based PDFs using Tesseract.js, one of the most trusted open-source OCR engines. Supports 10 languages — English, Hindi, French, German, Spanish, Portuguese, Chinese, Arabic, Russian, and Japanese. Process all pages, just the first page, or a custom range. View extracted text, copy it, or download it as a .txt file. A stats panel shows character count, word count, pages processed, and average confidence score.
Best for: Digitizing scanned documents, extracting text from image-based PDFs, making old documents searchable.
✍️ Sign PDF
Add your digital signature to any PDF in three ways. Draw it with your mouse or finger on a canvas (choose pen color and thickness), type your name in a cursive or formal font with a live preview, or upload an existing signature image. Place the signature anywhere on the page by dragging it, resize it from the corner handle, and choose which pages to apply it to.
Best for: Signing HR forms, agreements, contracts, applications, or any document that requires a signature without printing.
The Biggest Advantage — Your Privacy
Most online PDF tools upload your file to their servers. That means your salary slips, Aadhaar card, marksheets, bank statements, and legal documents are sent to a third-party computer somewhere on the internet.
TechPatraa PDF Tools works completely differently.
✅ All processing happens inside your browser
✅ Your file never travels over the internet
✅ No account creation required
✅ No watermark added to your output
✅ Completely free — now and always
