Introduction

So you need to compress one photo. One. That's the whole task. You type what you need into a search bar, click some random result, and suddenly there's a pop-up covering half the screen and a newsletter box asking for your email before you've done anything at all. You came here for one image. Somehow you've walked into a sales pitch.

I've been through this so many times I've lost count honestly. Same thing every single time. The site looks fine until you actually try to use it. Then the credit card form appears out of nowhere. Or the upload takes forever because your file is being sent off to some server somewhere and you don't know what's happening to it. Or the free version slaps a watermark on your output — a watermark, on a file you just converted on your own computer — and then charges you ten bucks to remove it.

At some point I just stopped looking. Built my own instead.

Moon Tools Hub is what came out of that frustration. A set of browser-based tools that each do one thing, do it properly, and don't ask you for anything in return. No account creation. No email verification. No card details. None of that.

What Actually Is This Site

The idea is not complicated. Give people tools that work without making them jump through hoops first.

Everything runs in your browser. That bit matters more than the rest of it. Your files don't go anywhere. That photo you compress, that PDF you merge, that block of text you paste in to check for differences — none of it leaves your device. There's no server on the other end receiving it. There's no database quietly keeping a copy. It's just JavaScript doing the work locally, on your own machine, and then it's done.

Fourteen tools right now. Three main areas — image work, PDF work, and general productivity stuff like password generation or text comparison or typing tests.

That list keeps growing, slowly. I add things when people email me asking for them, or when I run into a problem myself and can't find a decent free tool for it. Happens a lot actually.

Why Free, and Why No Sign-Up

People ask this constantly. Almost every week someone emails me asking what the catch is. There's a suspicious tone to it, like they're waiting for the other shoe to drop.

There isn't one. That's the honest answer.

Basic tools should be free. That's really the whole thing. The internet used to work like this, back before every small utility turned into a subscription service. A simple image compressor somehow became a platform with pricing tiers and a pro plan and an enterprise option. For compressing an image. Silly when you think about it.

I'm not doing that. Not planning to, either.

There are also no ads cluttering the page right now. No pop-ups either. No email verification loop you have to escape from. You open a tool, you use it, you close the tab. That's it. Nothing else to it.

Privacy works the same way. When you upload a file to some random website, you're basically trusting them with it. You have no idea what happens after that upload finishes. Whether it gets stored, shared, sold, whatever. With this site, there's nothing to trust because there's nothing to worry about. The file stays on your machine because that's where the processing happens anyway. Nowhere else for it to end up, really.

Who This Is For

Short answer — anyone who needs to finish something quickly without a bunch of hassle.

Longer answer, because there are actually a few different types of people who end up here.

Designers. You're dealing with images all day long. Resize this, compress that, convert this to that format, export it again, repeat. You want tools that don't slow you down or make you wait. That's genuinely what these are built for.

Students and office workers. Reports, PDFs, scanned documents, file conversions, that kind of thing. Nothing fancy required. Just something that works without crashing or hiding the download button behind a signup wall.

Developers. That's what I do for a living, so most of these tools started as things I needed for my own work. A quick password generator. A text diff checker. Small utilities you need maybe once a week and definitely don't want to install software for.

And everyone else. Maybe you just want to check your typing speed for fun. Or turn a photo into a PDF for a form you have to submit. Whatever the reason, if there's a tool here that does it, use it. Nobody's checking who you are.

The Tools, One by One

Image Compressor

I use this one almost every day at this point. You drop an image in, move the quality slider around, and a smaller file comes back to you. You decide how much compression happens. Keep the quality high and the image looks basically the same. Push it down low and you get a tiny file that loads instantly. Your call entirely, no automatic nonsense.

JPG to WebP Converter

WebP is what modern websites use for images. Smaller files than JPG at similar quality. If you run a blog or an online store, this one conversion alone can meaningfully speed up your site. Takes a couple of seconds, done. No settings screen, no options to figure out.

WebP to PNG Converter

Not everything supports WebP yet, unfortunately. When you need transparency or lossless output, PNG is the safer choice. Drop your WebP in, PNG comes out. Quality stays intact, no weird artifacts.

Image Resizer

Instagram post, website banner, passport photo, whatever. Different sizes for different purposes. Upload the image, enter the dimensions you need, download. That's it.

PDF Merge

Two reports become one file. Invoices from three months combined for your accountant. Scanned pages joined into a single document. Drag them in, arrange the order however you want, click merge. That's the whole process.

PDF Compressor

Big PDFs are genuinely painful to email. Most providers cap attachments at 25MB or so and then you're stuck. This brings the size down without turning the pages into mush. I use it for client proposals regularly and haven't had any complaints about quality.

Image to PDF

Photos into a single PDF. Useful for receipts, ID documents, expense reports — anything you'd otherwise have to scan. Upload the images, set the order, download the PDF.

PDF Split

Sometimes you need three pages out of a hundred-page document. This pulls out exactly what you want and saves them as separate files. Saves you from scrolling through pages you don't need. Sounds small until you're stuck doing it at 11pm.

PDF to JPG

The PDF gets broken down, one image file per page. So a ten-page document gives you ten JPGs, in order. Handy for presentations, social media posts, anywhere you need a picture rather than a document.

Password Generator

Weak passwords get accounts broken into, and most people reuse the same one everywhere. This generates random, strong ones. Set the length, choose whether to include symbols and numbers, generate. Copy it. Paste it somewhere. Save it.

Text Difference Checker

Comparing two versions of a document? Paste both, and the tool highlights what changed line by line. Useful for editing, proofreading, checking code changes, anything where spotting the difference matters.

Text File Maker

Sometimes you just need a plain .txt file and don't want to open a full editor. Type or paste your content, name the file, download it. Nothing weird happens to the file.

Typing Skill Test

Type a paragraph, get your words per minute, accuracy, and mistake count back in real time. Good way to track progress if you're actively practising. Or just a random thing to try when you're bored.

Text to Speech Converter

Long article you'd rather listen to instead of reading? Paste the text, pick a voice, let the tool read it out loud. I use this to proofread my own writing — hearing it back catches things my eyes skip over when I'm reading silently.

About Ads

Being straight with you here — AdSense ads will probably show up on the site at some point. Running a website costs money. Servers, domains, the whole thing adds up, and I'm not going to pretend otherwise.

But I'm not going to let ads ruin the experience. No pop-ups that block what you're reading. No auto-playing video with sound. No fake download buttons designed to trick you into clicking an ad. Just normal, standard ad placements that stay out of the way while you use the tools.

Monetisation keeps the site alive. It's not why the site exists.

How It's Built

HTML, CSS, and plain JavaScript. No frameworks, no bloated libraries loading in the background while you wait.

Image compression uses the Canvas API. PDF work relies on PDF.js and jsPDF. Text to speech taps into the browser's built-in speech synthesis. All of it happens on your own machine, nothing sent out, nothing processed on a server somewhere.

It's not fancy engineering. Just the right tools for each job, kept light because light is fast.

What's Coming

There's a list. Some of the items on it are half-built already. Some are still just notes on my phone that I haven't gotten around to yet.

A few things you can expect at some point:

If there's a tool you want to see, use the contact page and tell me. I read everything that comes in, even if I don't always reply quickly.

Wrapping Up

This started as something small I built for myself. A little collection of utilities I was tired of hunting for online every time I needed one. Then it slowly turned into an actual site with users and everything.

It's not a startup. It's not trying to disrupt anything or raise funding or whatever. It's just a set of tools that work, they're free, and they don't ask you for anything when you use them.

If you find something useful here, honestly, good enough for me.

So go try a few tools. Compress an image. Merge a couple of PDFs. See how quick it feels when the tool isn't fighting you for your email address or trying to upsell you on a pro plan you don't need.

I'll be here, adding more.
