Frequently Asked Questions

Does compressing an image reduce its dimensions?

No — this tool reduces the file size by optimising image data quality without changing the width or height (dimensions) of the image.

How much can images be compressed?

Typically 40–80% for photos at 80% quality. PNG images compress less than JPEGs. WebP achieves the best compression ratios of the three formats.

Are my images uploaded anywhere?

No — all compression happens in your browser using JavaScript. Your images never leave your device and are never stored on any server.

Can I compress multiple images at once?

Yes — select multiple files or drop them all at once. Click Compress All to process every image simultaneously, then Download All to save them all.

What quality setting should I use?

80% quality is the sweet spot for most use cases — it is visually indistinguishable from the original at significantly smaller file size. Use 60% for maximum size reduction and 90%+ for print-quality output.
