Why ConvertSamurai

Built for speed. Sharpened for privacy.

We built this tool the way we wanted one ourselves: fast, free, and respectful of your data.

Files stay on your device

Conversion happens entirely in your browser using JavaScript. We never see, store, or process your images on a server.

Instant conversions

No upload waiting, no server queue. The moment you click convert, processing begins on your machine.

Batch conversion

Drop a dozen files at once. Convert them all in one go. Download individually or as a batch.

10+ formats supported

No signup, ever

No accounts. No email. No "free trial." Open the page, convert, leave. That's the whole product.

Quality preserved

Smart defaults preserve as much quality as possible. Lossy formats use a balanced 92% quality setting by default.

Common questions

Frequently Asked Questions

Yes — completely free, with no hidden limits, watermarks, or signup. The site is supported by non-intrusive ads. You can convert as many images as you want, in any combination of formats.
No. All conversion happens locally in your browser using the HTML5 Canvas API and a few small JavaScript libraries for less common formats (HEIC, TIFF). Your images never leave your device.
There's no hard limit set by us — but since processing happens in your browser, very large files (over a few hundred megabytes) may slow down your device. For typical photos, expect conversions in well under a second.
Yes. Drop or select as many files as you want. Each file is converted in sequence and you can download them individually or all at once when conversion completes.
WEBP and AVIF produce significantly smaller files than JPG or PNG at the same visual quality. They're widely supported in modern browsers and are recommended by Google for faster website loading and better Core Web Vitals scores.
ConvertSamurai works in all modern browsers — Chrome, Firefox, Safari, and Edge. AVIF encoding requires Chrome 85+ or Edge 121+. HEIC files can be decoded in any modern browser through our integrated decoder.
