Is the image compression really done locally?

Yes, all compression happens directly in your browser. Your images are never uploaded to any servers, ensuring complete privacy.

What is the difference between Target Size and Quality modes?

Quality mode lets you manually adjust the compression ratio, while Target Size mode automatically calculates the best settings to reach a specific file size (e.g., 100KB) without sacrificing too much quality.

Which image formats are supported for compression?

We support compressing JPEG, PNG, WebP, and AVIF images. Note that PNG is a lossless format, so we recommend converting it to WebP or JPEG for the best compression results.

Will compression reduce the dimensions of my image?

No, our compressor only optimizes the file size and metadata. The pixel dimensions of your image remain exactly the same unless you also use the Resize tool.

Is there a limit to the file size I can compress?

Since processing is done locally, the only limit is your device's memory. Most modern devices can easily handle images up to 50MB.
