How to convert an image

1

Drop your image

Drag in any JPG, PNG, WebP, GIF, BMP or TIFF. The file loads in your browser — nothing goes to a server.

2

Pick the output format

Choose JPG, PNG or WebP. If converting to JPG or WebP, you'll see a quality slider to control the output.

3

Adjust quality (optional)

For JPG and WebP, set quality between 10-100. 90% is a safe default for most uses.

4

Convert and download

Hit Convert. Preview the output. Download it with the right file extension. That's it.

JPG vs PNG vs WebP: pick the right format

Format choice matters more than most people realise. Here's the short version.

JPGis the default for photographs. It uses lossy compression that works well with gradients and natural colour variation. The downside is that every save slightly degrades the image, and it doesn't support transparency.

PNGis the format for screenshots, logos, graphics with text, and anything that needs a transparent background. It's lossless, so the quality is perfect every time — but files are larger than JPG.

WebPdoes both better. Smaller than JPG for photos. Smaller than PNG for graphics. Supports transparency. Supported in every modern browser. If you're building a website and want to improve load times, converting your images to WebP is one of the highest-impact changes you can make.

Why convert without uploading?

Most online converters upload your image to their servers, convert it, then give you a download link. That's fine for public stock photos. But what about your personal photos, screenshots of private documents, or business assets you don't want on someone else's storage?

With this tool, conversion happens using the HTML5 Canvas API directly in your browser. Nothing is sent anywhere. No API call to a conversion service. No temporary file sitting on a server in some country you don't know about. Just your image, your browser, and the output file.

FAQ

What formats can I convert to?+
JPG, PNG and WebP. Those cover 99% of real-world needs. GIF output isn't supported since animated GIF requires a different approach.
Why would I convert to WebP?+
WebP files are smaller than JPG at the same quality. Same visual result, 25-35% less file size. All modern browsers support it. It's genuinely the better format for web use.
Can I convert a PNG with transparency to JPG?+
Yes. The tool fills the transparent areas with white before converting to JPG, since JPG doesn't support transparency. If you need the transparency preserved, convert to WebP or keep it as PNG.
Is there quality loss when converting PNG to WebP?+
At high quality settings (90%+), the visual difference is negligible. PNG itself is lossless, so any lossy conversion will technically reduce quality slightly — but at 90% you won't see it.
Can I convert multiple images at once?+
Not currently — it's one image at a time. Batch conversion is on the roadmap.
Does converting affect image dimensions?+
No. The dimensions stay exactly the same. Only the format and quality change. Use the resize tool if you need to change dimensions.
