USE CASES

When to use Compress an image?

Locally reduce image file size while immediately seeing the quality/size trade-off: usage presets, estimated output size, percentage saved and an aligned before/after comparison.

Meet an upload form or portal limit
Prepare a lightweight image for web or email

PRIVACY

Your data stays in the browser

Processed content is not uploaded to WorkToolset. Required libraries may be loaded by the site, but the file stays in the browser.

GOOD TO KNOW

Limitations to know

Automatic targeting applies to JPG/WebP; PNG remains a standard lossless export.
Very small targets may require reducing dimensions. The displayed result is recalculated locally before download.

HOW IT WORKS

A straightforward workflow.

1Load the image; WorkToolSet immediately computes a first compressed preview and estimates its output size.
2Choose a preset or adjust quality, then inspect artifacts with the before/after slider.
3Open precise settings only when you need an exact format, maximum width or file-size target, then download the copy.
