Browse our comprehensive collection of browser-based utilities. Find exactly what you need to manipulate, extract, and convert your data securely.
PDF Tools
Edit, merge, split, compress, rotate, watermark, password-protect, and sign PDF documents directly in your browser. No file leaves your device — every operation runs locally via WebAssembly.
OCR & Text Extraction
Convert photos of handwritten notes, receipts, prescriptions, and screenshots into editable digital text. Our 4-tier AI cascade uses local LSTM neural networks before escalating to cloud models for difficult handwriting.
AI Writing Tools
Humanize AI-generated text, paraphrase content, check grammar, summarize documents, translate between languages, and generate flashcards or quizzes from study material. Powered by Google Gemini AI.
Developer Tools
Format, minify, and validate JSON, XML, CSS, and SQL. Generate MD5, SHA-256, SHA-512 hashes and UUIDs. Encode and decode Base64, URL, and binary data — all utilities run entirely in your browser.
Medical Document Tools
Interpret lab results with plain-English explanations, simplify medical terminology, and decode difficult prescription handwriting. Designed for patients navigating their own health records — not a substitute for professional medical advice.
Text Utilities
Convert text case, count words and characters, sort or deduplicate lines, generate lorem ipsum, convert between binary/hex/ASCII, and extract emails or URLs from blocks of text. Instant results, no installs.
Document Conversion
Convert documents between formats: PDF to Word, PDF to Image, Image to PDF, and more. All conversions happen locally in your browser — no queues, no accounts, no file-size restrictions.
PDF OCR Tools
Extract readable text from scanned PDFs where the text layer is missing. Our AI OCR engine renders each page as an image, runs optical character recognition, and outputs clean copy-pasteable text.
Font & Typography
Draw each letter on a professional typographic canvas, apply AI stroke-smoothing, and export your handwriting as an installable .otf font file. Works in your browser — no software downloads required.
Data Extraction
Pull structured data from invoices, receipts, and scanned forms. Extract tables, totals, dates, and line items, then export to CSV or JSON for use in spreadsheets and accounting software.
Indian Document Tools
Designed specifically for Indian users and businesses. Instantly extract text from Aadhaar and PAN cards with specialized OCR, or generate GST-compliant invoices, salary slips, and rent agreements in one click.
Exam Document Formatter
Resize photos, signatures & documents to exact size for SSC, UPSC, IBPS, NEET, JEE and Railway exam portals.
Frequently Asked Questions
How does DoctorDocs' free tier work?
Core document utilities (merging, splitting, compressing, watermarking, signing, and standard printed OCR) are 100% free with no account required and no artificial file-size limits beyond your browser's RAM. Advanced AI features (like cursive handwriting decoding, medical prescription analysis, and document summarization) include complimentary trial scans per session, with unlimited high-volume processing available on our Pro plan.
Do my files get uploaded to a server?
It depends on the tool engine: local tools (PDF-Lib and Tesseract.js WebAssembly) process everything client-side on your own device—0 bytes are transmitted externally. Advanced AI models (Google Gemini Edge) transmit encrypted image payloads over TLS 1.3 to zero-retention endpoints where data is processed in volatile memory and immediately discarded.
What are the file size limits?
For local in-browser tools, you can process files up to 50MB directly in your browser. For cloud AI handwriting and medical tools, the free tier supports files up to 4MB, while Pro users can process documents up to 100MB.
What browsers are supported?
All tools work in any modern browser—Chrome, Firefox, Safari, and Edge—on desktop, tablet, and mobile. WebAssembly is supported natively across 96%+ of all global web browsers.
How is DoctorDocs different from iLovePDF or Smallpdf?
Traditional PDF services upload all your files to remote servers, impose strict daily task limits (often 2 tasks/day), and mandate costly monthly subscriptions. DoctorDocs processes core PDF operations entirely inside your browser cache with zero uploads, true data sovereignty under GDPR and DPDPA 2023, and includes specialized medical handwriting models not offered by generic utilities.
