Frequently asked questions
Are my files uploaded anywhere?
No. Every SnapToolz tool runs entirely in your browser using JavaScript and WebAssembly. Files are read locally, processed in memory, and the result is offered as a download. There is no backend.
Can I extract password-protected ZIPs?
Standard password protection isn't supported in the browser yet. Most ZIPs you'll encounter (downloads, GitHub releases, exports) are unprotected and work fine.
What's the largest CSV I can convert?
Up to your device's available memory — typically 50–500 MB on modern laptops. The parser streams the file, so you usually don't run out of RAM mid-conversion.
How does this compare to convertio, cloudconvert, or zamzar?
Server-based file converters upload your file, process on their hardware, and stream the result back. That's necessary for heavyweight conversions (video transcoding) but overkill for CSV↔JSON, ZIP extraction, or file-size analysis — what SnapToolz' File Tools cover. Browser-based versions are faster on small/medium files, work offline, and never put your data through a third-party pipeline. Useful when the dataset is private (customer exports, internal data, analytics dumps).
Is everything free?
Yes — every tool in this category and on the entire site is free with no sign-up, no daily limit, and no watermark.
