Why Not Just Use Convertio or CloudConvert?

Those tools work — but they upload every single image to their servers. If you're converting screenshots with sensitive info or personal photos, that's a privacy risk you don't need to take.

Zero Uploads

Your images never leave your device. Not to our servers, not to anyone's. True privacy by design.

Instant, Even Offline

No upload bar, no server queue. Conversion happens in milliseconds, right in your browser.

Truly Unlimited

No daily limits, no watermarks, no "sign up for more" walls. Convert as many files as you want.

Frequently Asked Questions

Are my images uploaded to a server?

No. This converter runs entirely in your browser using the HTML5 Canvas API. Your images are processed locally and never sent anywhere.

Can I convert HEIC (iPhone) photos?

Yes, if your browser supports HEIC. Safari and recent versions of Chrome can read HEIC files natively. If your browser doesn't support it, try Safari or use the MediaOptim desktop app for full HEIC support.

Will converting from PNG to JPG lose transparency?

Yes. JPG doesn't support transparency, so transparent areas will become white. If you need transparency, convert to WebP or keep PNG.

What's the difference between JPG and WebP?

WebP produces 25-35% smaller files at the same quality as JPG. It's supported by all modern browsers. Use WebP for web images and JPG when maximum compatibility matters.

Does conversion remove EXIF metadata?

Yes. Browser-based Canvas conversion strips EXIF data (camera info, GPS, etc.). To preserve metadata during conversion, use the MediaOptim desktop app.

Is there a file size or quantity limit?

No hard limits. Since everything runs in your browser, performance depends on your device. We recommend images under 50MB each for smooth processing.
