How does local image transcoding work?

The tool reads your source file, loads it into an off-screen HTML5 Canvas context, and exports the canvas pixels buffer as a new file format Blob locally inside the browser.

Do you upload my images to external servers?

No, never. The conversion executes entirely on your device using browser canvas rendering. Your sensitive graphics remain private.

Can I convert transparent PNGs to JPG?

Yes, but since JPEG does not support transparency alpha channels, any transparent background pixels will be converted to a solid color (defaults to white).

Frequently Asked Questions

Why convert JPG to PNG? +

PNG is ideal for screenshots, logos, and graphics containing text, as it supports lossless compression and transparency. JPG is better suited for photographic prints.

Does transcoding WebP require external libraries? +

No. Modern web browsers natively support WebP encoding and decoding via HTML5 Canvas standard arrays pipelines.

Are there quality trade-offs? +

Converting to JPG or WebP with low quality settings will reduce file size but introduce pixel artifacts. Keep quality above 80% for clean web layouts.
