Frequently asked questions
Which languages are supported?
English, Spanish, French, German, Portuguese, Italian, Dutch, Hindi, Japanese, Chinese (Simplified), Russian and Arabic. Each language model downloads only when you select it.
How accurate is it?
Clean screenshots and scans are usually near perfect. Photos of text at an angle, handwriting and decorative fonts are harder; the Clean up option boosts contrast first, which often helps.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Can I process many files at once?
Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
