Drop JPGs above, download WebP files. For photos, typically 25–35% smaller at matching visual quality, and each file shows what it weighed before and after, leaving the claim checkable on your own images.
Who this serves: anyone optimising a site or shop. Product photos, blog images, galleries. Every current browser renders WebP natively; most platforms accept it directly. Page weight drops, and page speed feeds rankings and bounce rates.
Double compression, and what it costs: JPGs were already compressed once at creation; converting is a second pass. At the default 82% it's invisible. What ruins images is repeated round-tripping. The working rules:
- Keep JPG originals as masters: conversion leaves the source alone.
- Serve the WebP copies: WebP is a delivery format, not an archival one.
- Convert once, in one direction, rather than moving a file back and forth between the two.
Quality slider: raise it for images inspected closely, and drop to ~70 for thumbnails where bytes beat pixels. Per-file byte counts make each setting's cost immediate.
If a platform refuses WebP: the original JPG is still sitting where it was, and the attempt has cost you nothing.
Full galleries drop at once, with per-file results, a ZIP for the set, and full resolution throughout.
