How to use Apex Studio Utilities
Everything you need to know about the 165+ tools — how they work, how your data is protected, and how to get the best results.
Getting Started
Find a tool
Browse all tools at /tools or use the search bar to find what you need. Tools are grouped by category — File Conversion, Image Tools, Developer Tools, and more.
Browse tools →Upload, paste, or enter input
Depending on the tool archetype, you'll either drag and drop a file, paste text, or enter a value. File tools show a drop zone — just drag your file in from your desktop or click to browse.
Adjust options (optional)
The right panel shows tool options: quality settings, format selection, output options, and more. Changes take effect immediately or on clicking the action button.
Download or copy the result
Results appear in the left panel. Use the Download button to save the file, or the Copy button for text output. For batch tools, "Download All" bundles everything.

How Privacy Works
Privacy isn't a feature we added after the fact — it's a consequence of how the app is built.
When you drop a file into an Apex Studio tool, it's read into your browser's memory using the FileReader API or a Blob URL. The processing (compression, conversion, etc.) runs using browser-native APIs like Canvas, SubtleCrypto, or WebAssembly. The result is written back into memory and offered as a download. At no point does any data leave your browser tab.
Frequently Asked Questions
Do my files get uploaded to a server?
No. Every tool runs entirely inside your browser using built-in Web APIs — Canvas, FileReader, SubtleCrypto, WebAssembly, and others. Your files are loaded into browser memory and never leave your device.
Why is there no file size limit?
Because there's no server processing your files, there's no reason to impose a limit. The practical ceiling is your device's available RAM — typically several gigabytes. Very large files may be slow on older hardware.
Do I need to create an account?
No account is required for any tool, now or ever. There are no paywalls, no rate limits, and no sign-up prompts.
How do I convert between two formats not listed?
If a direct conversion isn't listed, try a two-step approach: convert to an intermediate format first, then convert again. For example, HEIC → JPG → PDF.
Why does a tool show a "coming soon" page?
We're actively shipping tools. "Coming soon" pages appear when a tool is planned but not yet implemented. Check back — the suite grows regularly.
How do I report a bug or request a feature?
Use the contact form at /contact. Select "Bug report" or "Missing tool / feature request" from the topic selector.
Do you use cookies or analytics?
We use a single preference cookie (dark mode, etc.) that contains no personal data. If we ever add analytics, it will be privacy-respecting and cookieless. See the Privacy Policy for full details.
