Reduce image file size before you upload
Large images are the number one cause of slow web pages, bounced emails and frustrating uploads. This free image compressor lets you reduce image size right in your browser — no software to install and nothing sent to a server. Drop in a photo or screenshot, choose how much to compress, and download a leaner file that looks virtually identical.
You can compress JPEG, PNG and WebP images, or convert between them to squeeze out even more savings. Two controls do the heavy lifting: the quality slider trades a little detail for a much smaller file, and the resize option scales down oversized photos — a 12-megapixel phone picture rarely needs to be more than 1920 pixels wide for the web. Together they can reduce a photo to a few hundred KB while keeping it crisp on screens.
It's perfect for speeding up a website, meeting an upload size limit, shrinking email attachments, or preparing images for a marketplace, CMS or job application. Because everything runs on your device, your images stay completely private and the tool works even offline. This is one of many free browser tools on Uzetool — explore more tools as we add them.
Questions
Frequently asked questions
How do I compress an image?
Drag and drop your images into the tool, or click to browse. Choose a quality level and optional maximum size, and the compressor instantly creates a smaller version you can download. You can add several images at once for batch compression.
Is this image compressor free?
Yes — it's 100% free with no sign-up, watermarks, or usage limits. The tool is supported by unobtrusive ads so it can stay completely free to use.
Are my images uploaded to a server?
No. Everything runs locally in your browser. Your images are never uploaded or stored on any server, so the tool is completely private and works even offline.
Which image formats can I compress?
You can compress JPG/JPEG, PNG and WebP images. You can also convert between these formats — for example export a large PNG as a much smaller JPEG or WebP.
How can I reduce an image to a smaller file size in KB?
Lower the quality slider and reduce the maximum dimension. Both shrink the file — resizing a large photo to 1920px and setting quality around 70% typically cuts the size by 70–90% while still looking sharp on screens.
Will compressing reduce the image quality?
JPEG and WebP use lossy compression, so very low quality settings can add visible artifacts. At 70–80% quality the difference is usually invisible while the file is dramatically smaller. You can preview the result and adjust before downloading.
