How to Convert an Image

Upload any image file, choose the desired output format (PNG, JPEG, or WebP), and click Convert. For JPEG and WebP outputs, you can adjust the quality slider to control file size versus visual fidelity. Download the converted image when ready.

When to Use Each Format

Use PNG for images that need transparency or pixel-perfect quality like logos and screenshots. Use JPEG for photographs and complex images where small file size matters. Use WebP for the best balance of quality and compression — it is supported by all modern browsers and is ideal for web use.

Privacy First

This converter runs entirely in your browser. Your images are processed locally using the Canvas API and are never sent to any server. Close the tab and everything is gone.

Frequently Asked Questions

Can I convert a PNG with transparency to JPEG?
Yes, but JPEG does not support transparency. Transparent areas will be filled with a white background during conversion.
What is WebP and why should I use it?
WebP is a modern image format developed by Google. It provides superior compression compared to JPEG and PNG, resulting in smaller file sizes with similar quality.
Does conversion reduce image quality?
Converting to PNG is lossless. Converting to JPEG or WebP involves lossy compression — use the quality slider to control the trade-off.
Can I convert GIF or SVG files?
You can load GIF files, but only the first frame will be converted. SVGs can be loaded and rasterized into the chosen format.
Is there a file size limit?
No hard limit exists. Processing happens in your browser, so very large files may be slower on less powerful devices.
