Private PDF, JSON & image tools and playgrounds
Pick a tool by the job you need done. No account or sign-up, and most tools never upload your file.
🤖 Tools marked Agent-ready can also be called by AI agents in Chrome through WebMCP, with nothing to install. See the tools and how to try them.
Playgrounds

Kubernetes Playground
Learn Kubernetes with a sample app: watch pods and readiness, run a rolling update, break it on purpose and try kubectl-style commands. A teaching model, not a real cluster.
Log analysis tools New
Compare a good run and a bad run to see what is new, missing or changed, or open logs side by side and merge them by time. Files stay on your device.
Data Tools New
Make fake test data, make synthetic data with a known answer for ML, or clean a CSV step by step.
Email Playground New
Preview HTML email as you type, fill its variables from JSON and see what Gmail, Outlook and dark mode will break, line by line.
PDF Generator New
Write a page in HTML, fill it from JSON and see it on A4 pages as you type: invoices, receipts, letters, certificates, one PDF per record.
pgvector Playground New
Vector search in real PostgreSQL in your browser: document chunks with embeddings, cosine and hybrid search, HNSW and RAG queries.
ML and GPU Playgrounds New
Train scikit-learn and TensorFlow models on your own CSV, and learn how CUDA kernels run without a GPU. Files stay on your device.
TensorFlow Playground
Upload a CSV, train a neural network in your browser and watch loss, accuracy and the decision boundary. Nothing is uploaded.
scikit-learn Playground
Train and compare scikit-learn models on your own CSV in your browser, and see how each one scores. Your data stays on your device.
Test Data Generator New
Make realistic fake data for testing, up to 5 million rows as CSV, JSON or SQL INSERT, and mix in bad records on purpose.

Free online face blur. Faces are found automatically, then blurred, pixelated, blacked out or covered with an emoji. Private: nothing is uploaded.
Blur Faces in a Video New

About TinyPDF
TinyPDF is a set of free, single-purpose tools for PDF files, JSON data and images. Most of them run inside your browser, so documents such as contracts, ID scans, invoices and API responses are processed on your own device instead of being uploaded.
Are the TinyPDF tools free?
Yes. Every tool is free to use with no account or sign-up.
Are my files uploaded to a server?
Most tools read and process your file inside your browser tab, so it is never uploaded. Three tools are marked “Uses our server”: AI Text Detector, PDF AI Text Checker and Watermark Remover. They send your file to our server, which processes it and discards it immediately.
How can I check whether a redacted PDF is really redacted?
Open the PDF & Image Redaction Checker. It finds text hidden under black boxes, white-out or highlighter that can still be selected and copied, and it runs entirely on your device.
How do I compare two JSON files when the keys are in a different order?
Use JSON Compare & Schema Validator. It compares keys, values and data types instead of lines of text, so keys that moved up or down are not reported as changes. It can also validate JSON against a JSON Schema.
Is there an API?
JSON Query Playground is also available through an API. Tools with API access are marked “API available”.
How do I get help or report a problem?
