Lossy or lossless WEBP — which should I pick?

Lossy WEBP at quality 80 is great for photos and large compositions. Lossless WEBP suits screenshots, UI graphics, and anything with sharp text or flat colours.

Will the merged WEBP keep transparency?

Yes — alpha channels from input WEBPs are preserved, and the output WEBP supports full RGBA.

Do all browsers support the output?

Yes. WEBP is supported by every modern browser — Chrome, Firefox, Safari, Edge, and mobile equivalents.

How much smaller is WEBP vs JPG?

Typically 25–35% smaller at equivalent visual quality, sometimes more for graphics with flat colours.

Can I tune compression?

Yes — the quality slider goes from 60% (smallest) to 100% (lossless). Default is 82% for a great quality/size balance.

WEBP is the modern web image format that delivers JPEG-or-better quality at 25–35% smaller sizes — and Imglov's Merge WEBP to WEBP tool keeps that advantage intact. Drop your WEBP files (lossy or lossless, with or without transparency), choose a layout, pick quality, and export a single WEBP that stays as light as possible. Perfect for shipping a single hero asset built from multiple sources, combining icon variants for a single sprite, or stitching screenshots together for a fast-loading documentation page.
