Image Compressor
Shrink JPG, PNG and WebP images by quality or to an exact KB target. Compress as many as you like at once — your images are processed entirely on your device and never uploaded.
How to compress an image
Drop one or more images onto the box (or click to browse). Choose By quality and drag the slider, or switch to Target size and type a KB figure — the tool automatically finds the highest quality that fits, which is ideal when a form demands an image under 50 KB, 100 KB or 200 KB. Optionally cap the width to shrink large photos further, then download each result or grab them all at once.
Why compress images?
Large images are the most common reason web pages load slowly, and page speed is a ranking and conversion factor. Compressing photos before you upload them keeps pages fast, saves bandwidth and storage, and gets you past upload-size limits on forms and portals — without a noticeable drop in quality.
JPG, PNG or WebP — which should I pick?
JPEG gives the smallest files for photographs. WebP is a modern format that's usually 25–35% smaller than JPEG at the same quality and supports transparency, so it's the best choice for the web if you don't need older-browser support. PNG is lossless and best for graphics, logos and screenshots with sharp edges or transparency — its size is reduced mainly by lowering the dimensions rather than quality.
Frequently asked questions
Are my images uploaded to a server?
No. Compression happens entirely in your browser using the Canvas API. Your images never leave your device, which is faster and far more private than tools that upload your files.
How do I compress an image to a specific size like 50 KB?
Switch to "Target size (KB)", enter your number, and the tool searches for the highest quality that stays under that size. If even the lowest quality is too large, reduce the max width as well.
Is there a limit on file size or number of images?
There's no artificial limit and no signup. Very large images use more memory because everything runs locally, but typical photos compress instantly.
Does compressing reduce image quality?
Lossy formats (JPEG, WebP) trade a little quality for much smaller files; at 70–80% quality the difference is usually invisible. PNG stays lossless.
Is it free for commercial use?
Yes. The compressed images are yours to use anywhere, with no watermark and no restrictions.
