Image Compressor guide

The Image Compressor reduces image file size in your browser by re-encoding JPG, PNG or WebP images with practical quality settings. It is useful before uploading images to a website, sending them by email, adding them to documents, or keeping a smaller archive.

The preview and before/after size readout help you choose a quality level that still looks good. Compression is a balance: smaller files load faster, but very aggressive settings can add blur, banding or blocky artifacts.

When to use it

Preparing website images that load faster on mobile connections.
Shrinking screenshots before attaching them to email or support tickets.
Reducing photo size for forms with strict upload limits.
Creating smaller images before adding them to PDF or office documents.

How to use it

Choose or drop an image file into the tool.
Select the output format if the tool offers a choice.
Move the quality slider and compare the preview with the original.
Check the estimated or actual size reduction.
Download the compressed image and keep the original if it matters.

Example

Input

A 4 MB JPG product photo.

Output

A visually similar JPG around 700 KB, depending on quality and image detail.

Photos often compress much more than screenshots with sharp text.

Privacy

The image is decoded and re-encoded locally in your browser. It is not uploaded to UtilityTools.eu.

Limitations and accuracy notes

Repeatedly compressing the same JPG can reduce quality each time.
PNG screenshots with text may become blurry if converted to low-quality JPG.
Browser support for newer formats such as AVIF varies by device and browser.

FAQ

Will compression change image dimensions?

Compression usually changes file size, not dimensions. Use the Image Resizer if you also need smaller width or height.

What quality setting should I use?

Start around 75–85 for photos and compare the preview. Use higher quality for text-heavy images.

Are my photos uploaded?

No. Processing happens locally on your device.
