Complete Guide to Free Online PDF Tools
PDFyre provides a suite of free PDF tools that run entirely in your browser. No software installation, no account, no file uploads to any server. This guide explains every tool, what it does, and when to use it.
Why Use Browser-Based PDF Tools?
Most online PDF services like iLovePDF, Smallpdf, and Adobe Acrobat Online upload your files to their servers. This means your potentially sensitive documents — medical records, legal contracts, personal IDs, financial statements — pass through systems you do not control.
PDFyre processes everything locally using JavaScript in your browser tab. Your files never leave your device at any point. This makes it ideal for confidential documents, institutional records, and personal files you would not want on an external server.
All PDFyre Tools Explained
OCR PDF — Make Scanned PDFs Searchable
Flagship tool · multiple languages · Word-level text alignment
OCR (Optical Character Recognition) reads text from scanned PDFs and embeds an invisible text layer into the output. The result looks identical to your original scan but is now fully searchable, copy-pasteable, and screen-reader compatible.
Best for: Scanned textbooks, lecture notes, forms, contracts, old documents, medical records, legal papers.
Supports: English, Hindi, Arabic, Chinese, Japanese, Russian, French, German, Spanish and 90+ more languages.

Unlimited files · Original quality · No re-rendering
Combines any number of PDF files into a single document. Pages are copied byte-for-byte — no quality loss, no added watermarks, no recompression. Works with any PDF regardless of size or content type.
Best for: Combining chapters, joining scanned pages, assembling reports, creating course packets.

Multiple ranges · Custom file names · Original quality
Extracts specific page ranges from a PDF into separate downloadable files. You can define multiple ranges in one operation, each producing its own PDF. Pages are copied directly — no re-rendering or quality loss.
Best for: Sharing specific chapters, extracting individual documents from multi-document PDFs, separating sections.
📖 Read the Split Guide →Compress PDF — Reduce File Size
3 compression levels · Shows size reduction · Works best on scanned PDFs
Reduces PDF file size by re-rendering pages as JPEG images at lower resolution and quality. Most effective on scanned PDFs. Three levels available: Light (good quality), Balanced (recommended), and Aggressive (smallest size).
Best for: Scanned PDFs that are too large to email or upload. Not recommended for text-only PDFs created from Word or similar software.
📖 Read the Compress Guide →PDF to Images — Export Pages as PNG/JPEG
Adjustable DPI · PNG or JPEG · Individual downloads
Renders every page of a PDF as an image file. Choose between PNG (lossless) or JPEG (smaller), and set the render DPI from 72 to 300. Useful for embedding PDF content in presentations, websites, or documents that do not support PDF.
Best for: Extracting diagrams, creating thumbnails, embedding PDF pages in other documents.
Images to PDF — Combine Images into PDF
JPG · PNG · WebP · BMP · Multiple images per PDF
Combines multiple image files into a single PDF document. Each image becomes one page. Accepts JPEG, PNG, WebP, and BMP. Useful for creating PDF documents from photos, scans, or screenshots.
Best for: Converting photo collections, creating PDF portfolios, submitting multiple images as a single document.
Rotate PDF — Fix Page Orientation
90° · 180° · 270° · All pages or specific range
Rotates pages in a PDF without re-rendering. Uses pdf-lib's native rotation metadata — pages are not re-encoded as images, so there is no quality loss. Rotate all pages or only a specific range.
Best for: Fixing upside-down or sideways scans, correcting orientation before sharing.
Privacy — How It Works
Every tool on PDFyre uses the same architecture:
- PDF.js reads and renders your PDF pages inside your browser
- Tesseract.js (OCR tool only) runs the OCR neural network locally on your CPU
- pdf-lib builds the output PDF inside your browser's memory
- The finished file is downloaded directly to your device
- No file data is transmitted to any server at any step
PDFyre has no backend server infrastructure for file processing. Your files cannot reach us even if you wanted them to.
