JPEG (Joint Photographic Experts Group) uses lossy compressed encoding and is best for photographs, web images, and social media where smaller file size matters more than perfect quality. WebP (Web Picture Format) uses lossy or lossless encoding and excels at modern websites — Google-recommended format with superior compression for faster page loads. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
Typically 25–35% smaller than equivalent-quality JPEG — a 300 KB photo becomes ~200 KB WebP. Multiply across 500 images for real bandwidth wins.
Quality 80–85 matches JPEG-90 look. Batch once per use-case (hero vs thumbnail) rather than re-converting.
Universal in modern browsers (95%+) — serve WebP primary with JPEG fallback for the last stragglers.
No — conversion runs locally in your browser on Canvas. Saves never touch a meter — downloads on local tools are unlimited.

Bulk Image Format Converter
Convert image batches between JPG, PNG, WebP, and AVIF outputs (JPEG/PNG/WebP/AVIF/HEIC/HEIF/GIF/BMP/ICO/SVG inputs; HEIC via heic2any, SVG rasterized at intrinsic size or 1024px fallback) with a quality slider (10–100, default 80). Pair pages (?from/?to) preset the output. Flat ZIP renamed per file — local, 5-file guest batches, 25 signed-in, 500 Pro.

Convert one browser-decodable image to PNG, JPG, or WebP — the only outputs canvas can encode. HEIC/SVG/JXL/TIFF and other exotic targets fail honestly instead of pretending. Nothing is uploaded; every conversion runs in your browser.
