Why MultiTool Pro

World-class quality, professional-grade tools

What makes us different

Most free online tools upload your files to remote servers, force sign-ups, add watermarks, or block features behind paywalls. MT MultiTool Pro is the opposite: 60+ professional tools that run 100% in your browser, with no account, no upload, and no hidden costs.

Complete privacy

Files are read directly into your browser's memory using the File API, processed on HTML5 Canvas, and returned as downloads. There is no server-side processing.

Instant results

No queues, no processing pages, no waiting. Results appear the moment you click a button — often in under a second.

No signup, no limits

No account. No email. No quota. No watermark. Open the page, use the tool, download — that's it.

60+ tools, one page

Instead of bookmarking dozens of sites, keep everything in one workspace. Switch between image, PDF, text, calculator, converter and SEO tools with one click.

Good to know

Once loaded, most tools keep working even offline because the logic is already in your browser. Only PDF.js and share buttons need a connection.

Three steps

Pick, use, download — zero complications

1

Pick your tool

Choose any card from the catalog. Every tool opens instantly in the workspace — no reload, no redirect.

2

Add your content

Drop images, PDFs, paste text or enter values. Files are read locally with the browser File API.

3

Download & share

Export in your preferred format, or share the toolbox to WhatsApp, Reddit, Pinterest, Facebook and email.

Complete Walkthrough

How To Use MultiTool Pro

Every step, every tool — no guessing required.

1. Opening the Workspace

Click All Tools in the header, or scroll to the tool grid on the home page. Every tool card opens the workspace with that tool already selected.

2. Understanding the Layout

The workspace has two parts: a horizontal scroll of tool tabs at the top, and the active tool's control panel below. Click any tab to switch tools. Your work in each tool is preserved as you switch.

3. The Image Resizer (Most Used)

  1. Drop an image, click browse your files, or press Ctrl + V to paste.
  2. Set the width and height manually, or drag the Aspect Ratio Ruler to lock a specific ratio.
  3. Choose JPG, PNG, WebP or BMP as the output format.
  4. Click Apply changes, then Download.
Ruler tip

The Aspect Ratio Ruler ranges from 0.30 to 3.00 with tick marks at 1:2, 9:16, 2:3, 3:4, 1:1, 4:3, 3:2, 16:9, 2:1, 21:9 and 3:1. Click any tick or drag the thumb for precise control.

4. Text Tools

Paste or type into the input box. All text tools (word counter, case converter, slug generator, remove duplicates, sort lines, etc.) update live as you type. Click Copy to save the result.

5. Calculators

Scientific Calculator supports sine, cosine, tangent, log base 10, ln, square root, factorial, powers, percentages and the constants π and e. You can also type directly on your keyboard.

6. Developer Tools

Base64, URL encoding, HTML entity encoding, JSON formatting and hashing all work offline. Click the copy button after each result.

7. Sharing

Every page has a share bar with WhatsApp, Facebook, X, LinkedIn, Telegram, Reddit, Pinterest, email and copy-link options. Use the native share sheet on mobile when available.

8. Day & Night Mode

Click the Day / Night toggle in the header. Your choice is saved and remembered on your next visit.

9. Keyboard Shortcuts (Calculator)

  • 0–9 and . — numbers
  • + - * / — operators
  • ( ) — grouping
  • ^ — power · % — modulo
  • Enter or = — evaluate
  • Backspace — delete · Esc — clear

10. Data Safety

Your files never leave your device. The only exception is PDF.js (needed to read PDFs) which must load once from a CDN. After that, PDF tools work offline too.

FAQ

Frequently Asked Questions

Are my files uploaded to a server?

No. Every tool runs entirely in your browser using the HTML5 Canvas, File API, Web Crypto API and PDF.js. Your files never leave your device.

How many tools are there?

60+ professional tools across 12 categories: image, PDF, text, calculators, unit converters, developer, color, SEO, date/time, fun, security, and utility.

Which image formats are supported?

Read: JPG, PNG, WebP, GIF (first frame), BMP, AVIF. Write: JPG, PNG, WebP, BMP.

How does the PDF → Image converter work?

It uses the open-source PDF.js library to render each page onto an HTML5 canvas at your chosen scale, then exports it as PNG, JPG or WebP.

Is the Aspect Ratio Ruler useful?

Yes. Drag the rainbow slider or click a tick to instantly match 1:1, 4:3, 16:9, 9:16, 21:9 and more. Width and height update live with the lock on.

Is the scientific calculator safe?

Yes. It uses a tokenizer and shunting-yard algorithm — it never calls eval() — so it cannot execute arbitrary code.

Does it work on mobile?

Fully. The layout is responsive for phones, tablets, laptops and desktops. No app install needed — the site is a PWA-friendly single page.

Does it work offline?

Most tools keep working offline after the first load. Only PDF.js (loaded once from CDN) and share buttons need a connection.

Is there a file size limit?

No limit imposed by the site. Very large images (~30 MB+) may be slow on older phones because processing happens locally.

Can I use the output commercially?

Yes. Anything you create belongs to you — personal or commercial, no attribution required.

Do I need to create an account?

No. There is no signup, no email, no login. Your theme choice is saved only in your browser.

How do I switch between Day and Night mode?

Click the Day / Night toggle in the header. Your preference is remembered.

What is the difference between Image Resizer and Image Compressor?

Resizer changes dimensions (width × height). Compressor reduces file size by lowering quality at the same or similar dimensions. Often you'll use both.

Will the tools slow down my device?

No more than any browser tab. Processing is instant for typical files (under 10 MB). Very large PDFs with hundreds of pages will naturally take longer.
