Getting Started with GigAI Tools

GigAI Tools is a library of 250+ fast, free online utilities, for images, PDFs, documents, video, audio, QR codes, SVG, SEO and developers. There's nothing to install and no account to create. Open a tool, get your result, move on with your day.

I built this platform, so instead of a generic feature list, let me give you the tour I'd give a friend: what's actually happening when you use a tool here, where your files really go (mostly: nowhere), and the shortcuts that make the site quicker than it looks.

Where your files actually go

This is the question that matters most, so it comes first.

Almost every tool on this site processes your file inside your browser tab. When you compress a JPEG, the Image Compressor runs MozJPEG, the same encoder used by the Squoosh project, compiled to WebAssembly, right on your device. When you merge PDFs, the Merge PDF tool rebuilds the document with the pdf-lib library in browser memory. When you OCR a scanned page, OCR PDF downloads the Tesseract recognition engine to your machine and reads the text there.

The practical consequence: for these tools there is no upload, no server copy, and nothing for us to delete afterwards, because we never had your file.

A small number of conversions genuinely produce better results on a server, PDF to Word and Word to PDF use LibreOffice for faithful layout conversion. Those tools say so plainly on the page, and the files are processed ephemerally: received, converted, streamed back, deleted. Nothing is stored. If a tool is server-side, it tells you. If it doesn't say so, it's running locally. The full policy is in our privacy policy.

Finding the right tool in seconds

Three ways in, fastest first:

1. Keyboard search. Press ⌘K (or Ctrl+K) anywhere and start typing, compress pdf, heic, json. Results appear as you type and Enter opens the top hit.
2. Start from your problem. If you know the outcome but not the tool name ("my PDF is too big to email", "Instagram rejected my image") the Solve section maps everyday problems to the right tool.
3. Browse a Studio. Tools are grouped into focused studios: Image, PDF, Developer, QR and more. Each category page shows everything it contains.

There's also Smart Assist: drop in a file, describe your goal in plain words, and it analyzes the file, picks the right tools and runs them, still in your browser.

Chaining tools without re-uploading

The feature regular users lean on most: Workspaces. Instead of downloading a result from one tool and re-dropping it into the next, a Workspace keeps your file in place while you chain operations, crop, then resize, then compress, then convert, in one sitting. There's a dedicated workspace for each file family: images, PDFs, documents, audio, video, SVG and QR.

A typical workflow

Most tools follow the same pattern, so once you've used one you've basically used them all:

1. Open the tool
2. Drop in your file or paste your text
3. Adjust the options (defaults are usually right)
4. Download or copy the result

The defaults are chosen deliberately: the compressor's default quality, for instance, is the setting I'd pick myself for a web image. You can always override them, but you rarely need to.

Small things worth knowing

• Every tool page has a FAQ answering the questions people actually ask, quality settings, size limits, format quirks, privacy.
• The Glossary explains the jargon (what is a lossless format? what does DPI actually control?) in plain language, linked to the tools that use it.
• Platform-specific specs live under Image Sizes: exact current dimensions for every major social platform, kept up to date.
• Your history stays yours. The site remembers your recently used tools locally on your device to personalize the homepage. That data never leaves your browser either.

Where to go from here

The library grows continuously, and every new tool ships with the same rules: fast, honest about how it works, and private by default. The changelog tracks what's new, and the blog is where I write guides like this one. If a tool you need doesn't exist yet, tell me: reader requests genuinely shape what gets built next.

Pick a category and try something. The whole point is that it takes less time to use a tool here than to read about it.
