What Intera Tools is
Intera Tools brings together small, focused tools for the file chores that come up again and again. You can compress, resize, crop, rotate and watermark images, and convert them between JPG, PNG and WebP. You can merge, split, rotate and organize PDFs (reorder or delete pages), turn JPG images into a PDF, and turn PDF pages into JPG images. There is also a QR code generator.
The site is available in English and Korean, and every tool is free to use.
Why it exists
Simple tasks like shrinking a photo for an email or combining two PDFs should not require signing up for an account or sending personal documents to an unknown server. Many online tools ask for exactly that.
Intera Tools was built to offer a quicker, more private alternative: open a tool, pick your file, and download the result.
How it works
The tools on Intera Tools use JavaScript that runs inside your web browser. When you choose a file, it is read and processed on your own device. Your files are never uploaded to or stored on Intera Tools servers.
This approach is private because your files never leave your device, and it is often fast because there is no upload or download wait. Results stay in your browser tab until you download them or close the tab.
Our principles
These principles guide how Intera Tools is built and run:
- Free: every tool can be used at no cost, with no paid tiers.
- Private by design: files are processed locally in your browser and are not uploaded.
- No sign-up: there are no accounts, logins or passwords.
- Accessible and works on any device: tools are designed to work on phones, tablets and computers with a modern browser.
- Honest about limits: because processing happens on your device, very large files depend on your device's available memory, and encrypted (password-protected) PDFs are not supported yet.
How Intera Tools is funded
Intera Tools is funded by advertising, which is what keeps the tools free. Ads are kept outside the working area of each tool so they do not get in the way of your task. You can read more about ads and cookies in our Privacy Policy.
