For every lossy format, the quality slider lets you trade file size for sharpness on a 1–100 scale — PNG output stays lossless automatically, no slider needed.

Why Our Image Converter Stands Out: Flexible, Fast, and Fully Private

Every Format You Actually Need
JPG for photos, PNG for transparency, WebP for fast-loading websites, and AVIF for the smallest possible file sizes — switch between them with a single click.
Quality You Control
The quality slider gives you direct control over the size-versus-sharpness tradeoff for every lossy format, while PNG output stays lossless automatically.
Built for Batches
Load a whole folder of mixed-format images, convert them all to one target format in a single pass, and download everything together as a ZIP.
Private by Design
Every conversion runs on the Canvas API using your own device's processing power — your images are never uploaded anywhere, and no account is required.
