What is this tool?
An Image Converter lets you convert images between different formats (PNG, JPEG, WebP) directly in your browser. Upload one or multiple images, choose the target format and quality, and download the converted files. All conversion happens client-side โ your images never leave your device.

Frequently Asked Questions
What formats can I convert to?
You can convert to PNG (lossless, supports transparency), JPEG (compressed, best for photos, no transparency), and WebP (modern format with superior compression). Input formats include any image your browser can load: PNG, JPEG, WebP, GIF, BMP, AVIF, and SVG.
Does the quality change after conversion?
PNG is lossless, so there is no quality loss. JPEG and WebP are lossy formats โ the quality slider lets you control the trade-off between file size and visual quality. At 90-100%, the difference is barely noticeable.
Can I convert multiple images at once?
Yes. Upload multiple images at once, select your format and quality, and all images will be converted. You can download them individually or all at once.
Does JPEG support transparency?
No, JPEG does not support transparency. If you convert an image with transparency (like a PNG with transparent background) to JPEG, the transparent areas will be filled with white. Use PNG or WebP if you need transparency.
Are my images uploaded to any server?
No. All conversion happens entirely in your browser using the Canvas API. Your images never leave your device, and no data is collected or stored.
