Image Compressor, Resizer and Editor

Compress an Image Online

Upload your image, adjust the quality when available, process it, and compare the resulting file size with the original.

Original: 2.4 MB
Converted: 680 KB

The actual result depends on the image, format and compression settings.

Is Medihertz Image Converter Free?

Yes. Medihertz Image Converter is designed as a free online image utility.

There is no need to install desktop image-editing software just to perform common conversion, resizing, compression or editing tasks.


Do I need to install software?

No.

The tool works in a modern web browser, so you can use it from a desktop computer, tablet or smartphone.


Can I use the Image Converter on my phone?

Yes.

The interface is designed to work on both mobile and desktop screens.

You can upload images from your phone, select the required operation, edit or convert the image, and download the result.


Are my images uploaded to a server?

If your current implementation genuinely processes everything locally in the browser, use this wording:

Your images are processed directly in your browser and are not uploaded to a Medihertz server for conversion.

This is an excellent trust signal, but only keep this statement if the actual implementation supports it. Don’t make a privacy claim that the tool doesn’t technically provide.


Which image format should I use?

The best format depends on what you are doing.

Format Common use
JPG/JPEG Photographs and general images
PNG Graphics, logos and images requiring transparency
WEBP Modern websites and web images
AVIF Modern web delivery and efficient compression
GIF Simple animated or legacy graphics

There is no single best format for every image. Choose the format according to the image type, required quality, transparency needs and compatibility.


JPG vs PNG vs WEBP vs AVIF

JPG

JPG is widely used for photographs and images with many colors. It uses lossy compression, so very aggressive compression can reduce image quality.

PNG

PNG uses lossless compression and supports transparency. It is often useful for logos, graphics, screenshots and images where preserving exact visual information is important.

WEBP

WEBP supports both lossy and lossless compression and is widely used for modern websites.

AVIF

AVIF is a newer image format designed for efficient compression and modern web delivery. Browser support and encoding capabilities can vary.
