Compress Image Online — Free JPG, PNG & WebP Compressor

Large photos slow down web pages, blow past email attachment limits, and eat into upload quotas on job or exam portals. This tool shrinks JPG, PNG, and WebP images using the same MozJPEG and OxiPNG encoders that photo-editing apps rely on for real compression gains — not just the browser's built-in defaults — while running entirely on your device. Pick an output format, adjust the quality slider if you want a smaller file at a slight quality cost, and drop in as many images as you need; each one gets its own before/after comparison so you can see exactly what you're trading away before you download.

Frequently asked questions

Will compressing my image reduce its quality?
A little, depending on the quality setting you choose — that trade-off is unavoidable with lossy formats like JPG and WebP. The before/after preview lets you check the result before downloading, and the quality slider defaults to 75, a level most people can’t visually tell apart from the original.
Which output format should I pick — JPG, PNG, or WebP?
JPG is the safest default for photos and gets the smallest file size. PNG keeps transparency and sharp edges (logos, screenshots) but produces larger files. WebP usually beats both for size at similar quality, but a few older tools and platforms don’t accept it — check where you’re uploading to first.
Is there a file size or file count limit?
No. Since everything runs in your browser rather than on a server, there’s no upload limit to enforce and no per-file quota — just what your device can handle.
Are my images uploaded anywhere?
No. The compression runs entirely on your device in a background thread; your files never leave your browser.
Can I compress more than one image at a time?
Yes — drop or select multiple files and each one is compressed independently, with its own before/after preview and download button.
