Why use these tools?
Private by design
Your files are processed by your own browser and never uploaded anywhere. There is no server that could store, scan or leak your documents — the processing code runs on your device and works even on sensitive files like contracts or ID scans.
Fast and free
No upload and download round-trips means results in seconds, even for large files. Every tool is completely free — no accounts, trials, watermarks or artificial limits.
Works everywhere
The tools run in any modern browser on Windows, macOS, Linux, Android and iOS. Nothing to install and nothing to update.
Frequently asked questions
- Are these tools really free?
- Yes. Every tool on this site is free to use with no account, no watermarks and no daily limits beyond your browser's own memory.
- Are my files uploaded to a server?
- No. All processing happens locally in your browser using JavaScript. Your files never leave your device, which also makes the tools fast and safe for confidential documents.
- Do I need to install anything?
- No. The tools run in any modern browser on desktop or mobile — Chrome, Firefox, Safari and Edge are all supported.
- Is there a file size limit?
- Because files are processed in your browser, practical limits depend on your device's memory. As a guideline, images up to 25 MB and PDFs up to 50 MB work reliably.
