Why PublicSoftTools?
Completely Free to Use
Every core tool is free — no account required, no credit card, no trial period. We fund the platform through non-intrusive advertising so you never hit a paywall for essential features.
No Signup, No Installation
Open your browser and start using any tool instantly. There is nothing to download, no extension to install, and no account to create. Just visit the tool and get to work.
Private by Design
The vast majority of our tools process your files entirely in your browser using JavaScript and WebAssembly. Your documents, images, and text never leave your device. When server-side processing is needed (such as PDF to Word conversion), files are deleted immediately after processing and never stored.
Works on Any Device
Every tool is fully responsive and tested across Chrome, Firefox, Safari, and Edge on desktop, tablet, and mobile. The same tool works identically whether you are on a MacBook, Windows PC, iPhone, or Android tablet.
Professional-Grade Accuracy
Our tools are built on established libraries and verified against industry standards. JSON formatters validate against RFC 8259. PDF tools use PDF.js and pdf-lib. Image converters use browser-native codecs and Sharp. We document the technology behind each tool so you can verify how it works.
Constantly Growing
We add new tools every month based on user requests and emerging needs. The platform has grown from a handful of developer utilities to 228+ tools across PDF, image, AI, text, developer, calculator, SEO, converter, and utility categories.

Frequently Asked Questions
Are all the tools really free?
Yes — every core tool on PublicSoftTools is completely free with no account required and no hidden fees. We fund the platform through advertising displayed via Google AdSense, which allows us to keep all core features free indefinitely. We may introduce optional paid plans for high-volume API access and advanced AI features in the future, but the browser-based tool experience will always remain free.
Do you store or upload my files?
For the vast majority of tools, no — all processing happens entirely in your browser using JavaScript and WebAssembly. Your files, text, and data never leave your device. A small number of tools that require heavy server-side processing (such as PDF to Word conversion and PDF compression) do send your file to our servers over an encrypted HTTPS connection. In those cases, we display a clear notice on the page, process the file immediately, and delete it from our servers right after — we never store, log, or analyze the content of files submitted for processing.
Do I need to install anything?
No installation is required for any tool on the platform. All tools run in your web browser using modern web technologies including JavaScript, WebAssembly, and browser-native APIs. There are no plugins to install, no browser extensions required, and no desktop application to download. You can use every tool on a computer where you do not have administrator access — a school computer, work machine, or shared device.
Which image formats are supported?
The image converter supports JPEG, PNG, WebP, AVIF, GIF, BMP, TIFF, and HEIC/HEIF (iPhone photos). You can convert between any supported formats directly in your browser. The image compressor works with JPEG and PNG files and can reduce file sizes by 50–80% with minimal visible quality loss. The OCR tool supports JPEG, PNG, WebP, and BMP images for text extraction.
Can I use these tools on mobile?
Yes. Every tool on PublicSoftTools is fully responsive and tested on smartphones and tablets. The interface adapts automatically to smaller screens, touch inputs work correctly, and performance is optimized for mobile browsers. We test on iOS Safari, Android Chrome, and Firefox Mobile to ensure compatibility across the most common mobile browsers.
How accurate are the calculators?
All calculators use verified formulas from authoritative sources — financial formulas from standard actuarial and banking references, health formulas from peer-reviewed research (BMI from WHO standards, body fat from the Deurenberg equation, etc.), and scientific unit conversions from NIST standards. Results are displayed to appropriate significant figures and include the formula used so you can verify independently. Calculators are suitable for general reference; for decisions involving significant money or health, consult a qualified professional.
How do the AI tools work?
Our AI tools use a combination of approaches. The audio transcription tool runs OpenAI's Whisper model locally in your browser via WebAssembly — your audio never leaves your device. The background remover uses a machine learning segmentation model that also runs in the browser. Other AI features may call external AI APIs (such as the Anthropic Claude API for text analysis); when an external API call is made, we display a notice and do not log or store your input content beyond what is needed to process the request.
How do I request a new tool?
We welcome tool requests. If there is a utility you wish existed on PublicSoftTools, send us a message through the contact page with a description of what the tool should do and what use case it solves. We review all requests and prioritize the ones that align with our browser-based, privacy-first approach and that would be genuinely useful to a broad audience.
