Image Compressor

Compress for a reason, not just for a smaller number

A smaller image can make a web page faster, reduce attachment size and save storage, but compression is always a trade-off. The useful goal is not to make the file as tiny as possible; it is to make it small enough while keeping the image looking right for where it will be used.

How the compressor works

1. Choose a JPG, PNG or WebP image.
2. Select WebP or JPG as the compressed output format.
3. Adjust the quality slider and select Compress image.
4. Compare the original and new file sizes before downloading.

WebP or JPG?

WebP is a strong default for modern websites because it often gives a good balance between quality and size. JPG is useful when broad compatibility matters. If your PNG uses transparency, choose WebP if you want to keep transparent areas; JPG replaces transparency with white.

What the quality slider really changes

Lowering quality gives the encoder more freedom to discard detail, which can reduce the file size. The difference may be hard to see at first and then become obvious at lower settings. Photos, screenshots and graphics react differently, so there is no one setting that is best for every image.

Why a compressed result can sometimes be larger

If the original file was already well optimized, re-encoding it can produce little saving or even a larger file. The result panel reports the actual change instead of assuming compression always wins.

Common questions

Will compression change the dimensions?

No. This tool changes encoding and quality, not width or height.

Should I keep the original?

Yes, especially for important photos or graphics. Treat the compressed file as a delivery copy and keep the best source for future editing.

Can I compress a PNG without losing transparency?

Choose WebP output. JPG does not support transparent pixels.
