About this tool
This image compressor re-encodes a photo as WebP to shrink its file size. As you move the quality slider, the preview and the percentage saved update immediately, so you can balance quality against size by eye. Compression happens entirely in your browser, so your photo is never sent to a server.
How to use
- Drag in or select the image you want to compress.
- Move the quality slider (30-95) and watch the preview update live.
- Compare the original size, the compressed size, and the percentage saved.
- Download the compressed WebP file once you like the result.
Frequently asked questions
- What format does it compress to?
- Always WebP. At the same visual quality, WebP produces a smaller file than JPG, which makes it a good fit for compression.
- How much smaller will the file get?
- It depends on the photo content and the quality you choose. Lowering quality increases the percentage saved, and you can watch the before/after comparison update live as you adjust the slider.
- How much will image quality drop?
- You can adjust the slider anywhere from 30 to 95, and the compressed preview updates instantly, so you can see the trade-off and pick the point that looks right to you.
- Is my photo uploaded to a server?
- No. From the moment you select a file to compressing, previewing, and downloading, everything runs in your browser.
