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 our in-house AI models.
Image Editing
Crop, resize, upscale with AI, brighten, convert to black-and-white, and strip EXIF metadata from images. All transformations run client-side on the Canvas API — your photos are never uploaded.
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 — 50+ utilities that 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.
Frequently Asked Questions
Are these tools really free?
Yes. Every tool on this page is completely free with no account required for basic use. We sustain the site through non-intrusive advertisements. There are no hidden paywalls, no file-size limits on core tools, and no watermarks on downloaded files.
Do my files get uploaded to a server?
For the majority of tools — PDF utilities, image editors, OCR, and font creation — all processing happens locally inside your web browser using WebAssembly and the Web Canvas API. Your files never leave your device. Advanced AI-powered features (like AI summarisation or lab result interpretation) route data through our secure API with zero data retention.
Why do some tools require sign-in?
Computationally intensive AI features (like downloading a custom font file or running AI vision analysis) require a free DoctorDocs account to prevent abuse. Sign-in is free via Google or GitHub — no credit card needed.
What browsers are supported?
All tools work in any modern browser — Chrome, Firefox, Safari, and Edge — on desktop, tablet, and mobile. Camera-based scanning requires a device with a camera and browser camera permissions. WebAssembly (required for local OCR) is supported by 96% of browsers worldwide.
How is DoctorDocs different from iLovePDF or Smallpdf?
Most PDF services upload your files to remote servers, impose file-size caps, and require subscriptions for bulk use. DoctorDocs processes core PDF operations entirely in your browser — zero uploads, no size caps, instant results. Our medical and OCR tools are also tailored to healthcare documents, a niche that generic PDF platforms do not serve well.
