Is my image data sent to a server?

No. YogiCalculator uses client-side technology (WebAssembly and Canvas API) to process images entirely within your browser. Your files never leave your device.

Can I convert JPG to transparent PNG?

Yes, you can convert JPG to PNG. However, since JPGs do not have transparency, the background will remain solid unless you use an editing tool to remove it first.

How many images can I convert at once?

There is no hard limit. Since the processing happens on your device, it depends on your computer's memory. Converting 50-100 images at a time is typically very smooth.

Frequently Asked Questions

How do I convert JPG to PNG?

Simply drag and drop your JPG files into the upload box above. Select "PNG" from the global dropdown menu or on the individual image card, and click "Convert". Your file will be processed instantly and ready for download.

Is it safe to convert private photos here?

Yes, it is safer than server-side converters. YogiCalculator uses Client-Side Processing. This means the JavaScript code runs on your device (phone or computer). Your images are never sent over the internet to our servers.

What formats are supported?

You can upload almost any image format your browser supports (JPG, PNG, WEBP, GIF, BMP). You can convert them to:

JPG/JPEG: Best for photographs and web backgrounds.
PNG: Best for graphics, logos, and images requiring transparency.
WEBP: Modern format offering superior compression for web use.
ICO: Used for website favicons (includes 256px resizing).
SVG: Wraps raster images in vector format.

Does it support transparency?

Yes. Converting PNG to WEBP preserves transparency. When converting transparent images (PNG/WEBP) to JPG (which doesn't support transparency), we offer a Fill Color tool in the toolbar so you can choose a background color (white, black, etc.) instead of the default black artifacting.
