Usage Guide
Convert JPG to smaller WebP: the same visual quality at 25-35% less size — the standard move for web image optimization. Batch conversion, quality control, fully local.
1. Conversion flow
- Drop JPG images (batch supported).
- Quality defaults to 90% (visually lossless); drop to 75-80% for smaller files.
- Compare sizes and download everything.
2. Where WebP fits
Fits: website assets (bandwidth and speed), app bundled images, blog media — every modern browser supports it. Think twice: images headed into legacy Office/Photoshop/print pipelines, or old Android WebViews. Rule of thumb: WebP for humans to view, JPG for software to chew.
3. One advanced use
- Site-wide WebP conversion is a high-ROI LCP lever: combined with dimension compression in our image-compressor, hero weight often halves with immediate speed gains.
4. Quality settings and EXIF stripping
WebP at quality 80 is the practical sweet spot: typically 25-35% smaller than the source JPG with no visible difference. Below 70, gradients band and skin tones posterize. One often-desired side effect: WebP encoders strip EXIF metadata (GPS coordinates, camera serial) by default — useful for privacy when publishing photos, destructive if the metadata matters (photography portfolios). Keep the original if EXIF must survive; WebP is for web delivery copies, not archival masters.
5. Practical tips before converting
- Batch-convert whole image folders in one session — each file is independent.
- Compare original and WebP side by side at 100% zoom before deleting anything.
- Keep originals: WebP strips EXIF metadata, which is a privacy win but a loss for archives.
FAQ
All mainstream browsers (Chrome/Safari/Firefox/Edge) and most modern software handle WebP in 2026. A few legacy systems and professional tools (old Photoshop, some office suites) may not, and printing pipelines plus some email clients are weaker still — confirm the destination before converting.
25-35% smaller than JPG at equal quality, far smaller than PNG, with transparency and animation support — ideal for web and app assets. Batch conversion and quality options are supported.
Photographic images tolerate a quality drop in exchange for size; screenshots with text do not, since edges blur fast. Compare quality and file size on a small sample first, then batch.
Better not. The conversion is lossy, so keep masters and exports in separate places — rollback or recompression depends on the originals. Very old environments may still need a JPEG/PNG fallback, and it pays to spot-check in the target browser before shipping.
No. Encoding is done by the browser locally; both the originals and the converted files stay on your machine.
