Toolish (toolish.xyz) is a collection of free web tools and learning apps that run the moment you open your browser — no signup, no install. From image, video and PDF editing to learning apps that help children with English, numbers and memory, it's an independently run place to get those "not worth installing dedicated software for, but occasionally needed" tasks and lessons done on the spot.
This page explains, as concretely as we can, what Toolish is built to value, how it actually works, and who runs it. The goal is to be open about the site's background so you can use the tools with confidence.
Process in your browser wherever possible
Background removal, blurring, OCR, puzzles, color extraction, PDF editing and more — most tools process the image or PDF you choose entirely inside your device (the browser), without sending it to a server. Even the tools that use AI only download the model itself from a CDN the first time; the image never leaves your device. The exception is the one-time file sharing tool 'SendOnce,' which by design has to hold the file, so it explicitly uploads it (and expires automatically after 10 minutes).
Free, with no cap on how often you use it
Every tool is free, with no usage limit. Running costs are covered by ads — which is exactly why we keep ads within reason and lay them out so the content, not the advertising, stays the main thing.
Build one useful thing at a time
We prioritize each tool being genuinely useful over racking up numbers. New tools start from a real moment where we or someone close to us thought 'I want this,' and we check that it works well before publishing.
Don't hide what's saved or sent
Each tool's page states whether it talks to anything external and what it stores on your device. Scores and settings are saved only in your device's localStorage — they're never sent to our servers.
Toolish is an independent project that began from a simple wish: to solve everyday little problems in the browser alone, without installing dedicated apps. Strip location data from a photo, reorder pages in a PDF, teach a child numbers or English through play — for each concrete situation like that, we built one tool at a time and published it so others with the same problem could use it too. More than flashiness, we value the ease of opening it, using it right away, and closing it when you're done.
Toolish is a React single-page app, but every page is pre-rendered to static HTML so search engines and crawlers can read the content correctly. For image processing we use AI models and WebAssembly that run on your device, and for video export we use the browser-native WebCodecs — choices made to keep work on the device rather than on a server. Which tools do and don't make network requests is stated on each page, and security headers (forced HTTPS, a Content Security Policy, and more) are in place.
The image and PDF tools suit individuals without dedicated software, or anyone who wants to handle sensitive documents as much as possible on their own device. The learning apps (English listening, counting money, katakana, memory, observation, typing and more) are aimed at preschool-to-primary children and their parents, with the goal of learning through play. So you can pick what fits your age and purpose, each tool's page includes a 'great for' section of use cases and a set of frequently asked questions.
Toolish is planned, developed and run by an individual, not a company. The design of the tools, the writing, and the illustrations (icons) are each made by hand. Feedback, requests and bug reports are always welcome through the contact form, and what we receive feeds into future improvements. How we handle privacy is set out in the Privacy Policy, and the terms of use are set out in the Terms of Use.
Published tools keep getting worked on in response to friction points and requests. Rather than adding tools just to grow the count, we only add ones we've confirmed are genuinely useful. The descriptions, how-to guides and FAQs are also revised to match how tools are actually used.
