Is this really free with no limits?

Yes. No daily limits, no conversion caps, no premium features locked behind a paywall. Use it as much as you want.

Why don't you require signup?

We don't need your email because we don't process your files on a server. No server costs means no need to monetize user data.

How do you make money?

ConvertMinify is a free tool. We don't sell data, show intrusive ads, or charge for features.

Is it safe without an account?

Safer than sites that require accounts. No personal information to leak, no password to breach, no data stored anywhere.

What formats are supported?

Input: JPG, PNG, WebP, GIF, AVIF, HEIC, SVG, TIFF, BMP, ICO. Output: JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, ICO.

Can I use this on mobile?

Absolutely. ConvertMinify is fully responsive and works on any phone or tablet with a modern browser.

Why Choose ConvertMinify

Most "free" online image converters come with catches: 3 conversions per day, mandatory signup, watermarks on output, or uploading your files to their servers. ConvertMinify has none of these restrictions because our business model doesn't depend on restricting your usage or collecting your data.

Everything runs in your browser using modern Web APIs. There are no servers processing your images, which means there are no server costs to pass along to users. The result is a genuinely free tool with no limits — and the bonus of complete privacy since your files never leave your device.

Whether you need to convert one image or a thousand, from any format to any format, ConvertMinify is here for you. No signup, no limits, no compromises.
