About the Image Converter
Conversion runs entirely in your browser using the HTML5 Canvas API — your images are never uploaded to a server. Drop any number of images, choose an output format, and download individually or as a ZIP.
Format guide
JPEG — Best for photos. Lossy compression keeps file sizes small. Transparent areas become white. Widely supported everywhere.
PNG — Lossless — no quality loss at all. Supports transparency (alpha channel). Best for screenshots, logos, and graphics with text.
WebP — Google's modern format. Roughly 25–35% smaller than JPEG at the same quality. Supports transparency. Supported in all modern browsers.
Frequently asked
Are my images uploaded anywhere? No. Everything runs locally using the Canvas API. Your files never leave your device.
Will converting PNG to JPEG lose transparency? Yes — JPEG doesn't support transparency, so transparent areas are filled with white. Use PNG or WebP to keep transparency.
Is there a file size limit? No server limit. Very large images (50 MB+) may be slow depending on your device.
What formats can I upload? Any image your browser can display — JPEG, PNG, WebP, GIF (first frame), BMP, and SVG.
