• Part of a full image tools suite, so related image compressor tasks are one click away.

What people use Image Compressor for

• Getting a photo under a file size limit for a job application, passport renewal or visa portal.
• Reducing page weight before uploading images to a website or online shop.
• Shrinking a batch of holiday photos to email or archive without losing visible quality.

Image Compressor: limits and things worth knowing

• Quality is adjustable and the resulting size is shown before download, so you can find the point where the file is small enough and the image still looks right.
• JPEG compression is lossy and cumulative — compressing an already-compressed image degrades it further. Always start from the original.
• PNG is lossless and compresses poorly for photographs; converting a photo from PNG to JPEG or WebP usually saves far more than any quality setting.
• Batch processing runs entirely on your device, so a hundred images take as long as your hardware needs and not a second of upload time.

Is it private and secure?

Your privacy is built in. Image Compressor does all processing on your own device using client-side code, so your files are never transmitted, stored or seen by anyone — including us.

Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.

You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.
