Why Choose Toolo?

- ✅ Available immediately without registration
- ✅ Browser tools process locally. Server tools still need an upload to finish.
All-in-One Free Online Utility Suite
Toolo is a set of free web tools for everyday work: PDF compress, merge, split, convert, and page extract; image compress, resize, convert, crop, and watermark; CSV, JSON, and Excel conversion; text count, case change, and compare; plus typing practice, Lorem Ipsum, developer helpers, URL shortening, QR codes, and Base64.
You do not need to install desktop software or create an account. Most PDF, image, file, and text tools run in the browser with JavaScript (pdf-lib, PDF.js, Canvas, and similar libraries—not WebAssembly as a product claim). URL shortening stores links on the server. Image watermark and advanced image compress upload files to the server (Sharp). Typical file caps are about 20MB per file; PDF merge allows up to 10 files.
Comprehensive Web Utilities Suite
Browse the categories on this page. Details and limits are listed on each tool:
PDF Utilities
Compress one PDF (pages are rasterized to JPEG, so selectable text is not kept), merge up to 10 PDFs, split or extract pages, and convert pages to JPG or PNG. Password protect and unlock are not available yet.
Image Processing Tools
Compress, resize, convert, and crop in the browser (JPG, PNG, WebP; GIF input is often the first frame). Canvas compress is lossy, not quality-lossless. Advanced compress and watermark run on the server (watermark: JPG/PNG/WebP, output PNG). BMP is not a listed format. Max size is typically 20MB.
Data & File Conversion
Convert among CSV, JSON, and Excel (XLSX) in the browser. Excel uses the first sheet. JSON is treated as an array of objects. Maximum 20MB. Nested hierarchy is not a guaranteed round-trip.
Text Editing & Manipulation
Count characters, words, sentences, lines, and paragraphs as you type. Change case to uppercase, lowercase, Title Case, or Sentence case (not camelCase). Compare two texts by matching whole lines. Typing practice and Lorem Ipsum are separate categories on the home grid.
Developer & General Utilities
Developer tools include JSON/YAML, HTML/Markdown, XML/JSON, CSS format/minify, favicon, and timestamp. URL shortener saves the original URL on the server (optional custom code and expiry; click counts are stored, not shown here). QR codes are client-side PNG (100–1000px). Base64 encodes and decodes UTF-8 text in the browser, not file uploads.
Frequently Asked Questions (FAQ)
Is Toolo completely free to use?
Yes. Tools are free, with no account and no paid feature wall. There are still practical caps such as file size (often 20MB), PDF merge (10 files), and QR text length (2,953 characters). Those are limits in the tools, not a subscription.
How does Toolo protect my privacy and file security?
Most PDF, image, spreadsheet, and text tools process data in your browser and do not upload the file for processing. Exceptions: the URL shortener stores original URLs; image watermark and advanced image compress send files to the server. Do not treat every tool as fully local.
Do I need to download or install software to use Toolo?
No. Toolo runs in a modern web browser (Chrome, Safari, Firefox, or Edge) on desktop and mobile. Some tools need enough device memory for large files.
