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.

To reduce file size after converting, use the Image Compressor. To enlarge a small image, the Image Upscaler scales up 2×–4× using Lanczos resampling. For iPhone HEIC photos that won't open on Windows, the HEIC Converter handles batch conversion.
Frequently Asked Questions
Are my images uploaded to a server?
No. Conversion runs entirely in your browser using the HTML5 Canvas API. Your images never leave your device and are never transmitted anywhere.
Is the Image Converter free?
Yes. There is no cost, no account, and no signup required. Every format and feature works without any payment.
Do I need an account to use it?
No account, no email, no login. Open the tool and use it.
Will converting PNG to JPEG lose transparency?
Yes — JPEG does not support transparency, so transparent areas are filled with white. Use PNG or WebP output to preserve transparency.
What input formats are supported?
Any image your browser can display — JPEG, PNG, WebP, GIF (first frame only), BMP, and SVG.
Is there a file size limit?
No server-side limit. Very large images may be slow depending on your device memory.
