Convert images to WebP without uploading them
WebP is the de-facto standard for web images. Converting to it typically reduces file size by 25–35% compared to JPEG, improving page speed and Core Web Vitals without loss of quality.
ConV converts to WebP entirely in your browser using libwebp compiled to WebAssembly. Nothing is uploaded — not filenames, not pixels.
Batch convert entire image directories, export as ZIP, and upload directly to your CMS — no intermediate cloud step required.
Vantaggi
- Converts JPEG, PNG, AVIF to WebP locally
- libwebp WASM — same codec quality as popular cloud converters
- Batch mode: convert dozens of files in one session
- ZIP export for fast CMS or FTP upload
- EXIF metadata removed during conversion
Casi d'uso
- Web developers preparing WebP assets for production
- Shopify and WooCommerce teams preparing product images
- Agencies converting client image sets under confidentiality agreements
- Performance engineers reducing image payload for Core Web Vitals
Come funziona
- 01
Drop JPEG, PNG, or AVIF files
- 02
Select WebP as output format; set quality (0–100)
- 03
Workers convert in parallel — results appear as they complete
- 04
Download as ZIP or save individual files
Limiti realistici
Animated WebP from video or GIF sources is not supported. Very high-resolution source images may be slower on low-spec hardware.
FAQ
Is WebP conversion lossless or lossy?
Both modes are available. Lossy is typical for photos; near-lossless (quality 90–100) works well for graphics and illustrations.
Can I convert WebP back to JPEG?
Yes. ConV supports WebP as both input and output. Convert WebP → JPEG by selecting JPEG as your output format.
How much does WebP reduce file size?
Typically 25–35% vs JPEG and 25–50% vs PNG at equivalent visual quality, though results vary by source image content.
Are my files uploaded to a WebP conversion API?
No. ConV converts locally in your browser. No files are sent to any server.
Correlate
Convert images to AVIF locally in your browser
AVIF is the next-generation image format backed by the Alliance for Open Media. It achieves 30–50% better compression than JPEG at comparable visual quality and often outperforms WebP.
Compress multiple images locally and export them as ZIP
Processing images one at a time is impractical for agencies, content teams, and e-commerce workflows. ConV's batch mode handles dozens of images in a single session with parallel encoding and ZIP export.
Optimize images for Core Web Vitals without cloud uploads
Images are the largest contributor to Largest Contentful Paint (LCP) — the most impactful Core Web Vitals metric. Reducing image file size and using modern formats (WebP, AVIF) is the most effective single optimization for most pages.
