About ToolForge

Who makes this

ToolForge is built and run by toolforge.website. Started ToolForge in May 2026 and has built and maintained it since, writing every tool on the site and the documentation that goes with each one.

That is worth saying plainly, because a lot of sites in this corner of the web are anonymous. One person writes the code, writes the explanation on every tool page, and answers the email. If something here is wrong, there is nobody else to pass it to — and the fastest way to get it fixed is to say so at toolforgewebsite@gmail.com.

ToolForge is also on LinkedIn.

Why it runs in your browser

Most online utilities work by taking your file, sending it to a server, doing the work there, and sending something back. That is easier to build, and it means a stranger’s machine has had a copy of your file — a passport scan, a contract, a screenshot with a customer’s details in it — for however long they choose to keep it.

ToolForge does the work where the file already is. When you compress an image here, your browser reads it, re-encodes it on a canvas, and hands it back as a download. Nothing is transmitted, because there is no upload endpoint to transmit it to: the site is statically generated and stores nothing. The practical upshot is no queue, no file-size ceiling imposed by someone else’s disk, and no account.

Thirteen tools are exceptions, and they have to be — a DNS lookup cannot happen on your laptop alone. Each one says so on its own page, and the methodology page lists all thirteen with the service each contacts and exactly what gets sent.

What is here

215 tools across 11 categories. The largest group by some distance is the calculators — 88 of them, covering loans and interest, body composition and nutrition, everyday maths, and a set of physics and chemistry tools. Each one implements a published formula and names it on the page, so you can check the arithmetic rather than trust it.

• •Images — compress, resize, crop, convert between JPG, PNG, WebP, AVIF and HEIC, and strip the EXIF and GPS data that photos carry without telling you.
• •Developer utilities — format and diff JSON, encode and decode, hash, build cron expressions, inspect a HAR file.
• •Text — count words and characters, check readability, convert case, compare two drafts line by line, preview Markdown.
• •Everything else — QR codes and barcodes, passwords, SEO checks, network lookups, and a handful of creative tools. Browse the full list.

How it pays for itself

Advertising, and the occasional coffee. There is no paid tier, nothing is held back behind a signup, and no tool has a watermark or an export limit that a payment would remove. Every tool on the site is the whole tool.

Ads are kept out of the way of the thing you came for, and the files you process are never shared with an advertiser — they never leave your device in the first place, so there is nothing to share. What analytics and advertising do collect is set out in the privacy policy.

What this site will not do

• •Ask you to create an account, or for an email address, to use a tool.
• •Claim a tool is private when it is not. Where data leaves your browser, the page names the service that receives it.
• •Give you financial or medical advice. The loan and health calculators do arithmetic against a stated formula; what to do with the answer is a conversation for someone who knows your situation.
• •Ship a tool that does not work. A control that looks interactive is interactive; if a tool is broken, it comes down until it is fixed.

Get in touch

Bug reports and wrong answers are the most useful mail to get — include the tool, what you entered, and what you expected. Requests for tools that do not exist yet are welcome too.
