What image formats can I convert between?

The converter supports JPEG, PNG, and WebP as output formats. It can read any format your browser supports as input, which includes JPEG, PNG, WebP, GIF, BMP, and SVG. This covers the vast majority of web image formats.

Does converting to PNG increase file size?

Usually yes. PNG is a lossless format, so it preserves every pixel exactly — which means files are typically larger than JPEG or WebP equivalents. If file size matters, use JPEG (for photos) or WebP (for the best compression-to-quality ratio on modern browsers).

What is the quality slider for?

The quality slider controls lossy compression for JPEG and WebP output. At 100%, the output is near-lossless (large file). At 70–80%, quality is excellent and files are significantly smaller. Below 60%, you may notice compression artifacts. PNG ignores the quality slider because it's always lossless.

What happens to transparency when converting to JPEG?

JPEG does not support transparency. When converting a PNG with a transparent background to JPEG, the transparent areas are filled with white. If you need to preserve transparency, convert to PNG or WebP instead — both support alpha channels.

Is my image uploaded to a server?

No. All conversion happens in your browser using the HTML5 Canvas API. Your image is never sent to any server. The converted result is generated locally and downloaded directly from your browser.
