How to use the image compressor

  1. 1

    Select or drop a JPG, PNG or WebP image.

  2. 2

    Choose an output format and, for JPG or WebP, a quality level.

  3. 3

    Select “Compress image” and compare the original and new sizes.

  4. 4

    Download the result, or change the settings and compress again.

What the quality setting does

JPG and WebP are lossy formats: they make files smaller by discarding detail that is hard to see. A lower quality value discards more, so the file shrinks but edges and fine textures can soften or show blocky artifacts.

For photos, a quality between 70% and 85% is usually a good balance. Screenshots and images with text tend to need a higher setting to stay crisp.

Compressing PNG images

PNG is lossless, so browsers do not offer a quality setting for it. If you keep PNG as the output, the image is re-encoded without losing any detail. That can make the file smaller or larger depending on how it was originally saved.

For a real reduction, convert to WebP, which keeps transparency and is usually much smaller, or to JPG if you don’t need transparency. Reducing the dimensions with the image resizer also cuts PNG sizes substantially.

Why a file can get bigger

An image that was already compressed well can grow when it is re-encoded at a higher quality than before. When that happens the result is labelled as larger, so you can lower the quality, try another format, or keep your original.

Frequently asked questions

How large can my image be?

Up to 50 MB and 40 megapixels per image. Very large images need a lot of memory, so phones and older computers may need smaller images.

Does compression change the image dimensions?

No. The width and height stay the same. To make the image smaller in pixels as well, use the image resizer.

Is the photo’s metadata kept?

The compressed file is newly encoded by your browser, which does not copy camera metadata such as EXIF details or GPS location. Any rotation stored in the metadata is applied to the pixels so the picture still appears the right way up.

Are my images uploaded anywhere?

No. Compression happens in your browser using its built-in image encoders. The image is not sent to our servers.
