DRAG TO COMPARE

Can you spot the difference?

The left side is the original JPEG. The right side is the browser-generated WebP at quality 84. Move the divider across fine textures, glass reflections, and hard shadows.

This is one measured example, not a universal quality claim. Results depend on image content, output dimensions, browser encoder, format, and quality setting.

WORKED EXAMPLES

Three original samples cover texture, crop-safe dimensions, and transparency. Load one, generate it, then compare the source and result.

Results vary by browser and image content; byte savings appear only after this browser creates the output.

FORMAT NOTES

Choose the output your image needs

JPEG

Best for photographs. Smaller files use lossy compression and transparency uses the selected background colour.

PNG

Best for graphics and transparency. Palette quantization reduces colours for a smaller, near-lossless file.

WebP

A modern balance of quality and size with transparency support in current browsers.

Processing stays on this device. Re-encoding removes source metadata such as EXIF. Keep the original when metadata matters.
