How to compress a WebP image
WebP is a modern format that typically produces files 25–35% smaller than JPG at the same visual quality, and it supports transparency like PNG. Compressing to WebP lets you use a quality slider just like JPG, but you get more image for every kilobyte. It is supported by every current browser.
This WebP compressor runs entirely in your browser. Drop in a WebP file, adjust the quality until the preview looks right, and download the smaller version — no uploads, no sign-up, and no watermark.
How to use it
1. Drop your WebP image onto the drop zone or click to browse.
2. Use the before/after slider to compare the original with the compressed result.
3. Drag the quality slider until the file is as small as you want while still looking good.
4. Download the WebP image. Everything is processed on your device.
Choosing the right quality
A WebP at 75% quality usually looks as good as an 85% JPG while being noticeably smaller. Because WebP is so efficient, you can often push the quality a little lower than you would with JPG before artifacts show up.
WebP is an excellent default for the web. Keep JPG only when you need maximum compatibility with older software, and keep PNG when you need guaranteed lossless quality for graphics.
Common mistakes to avoid
A few habits quietly ruin image quality or waste file size:
- Compressing from an already-compressed copy instead of the original, which stacks up quality loss. - Pushing lossy quality so low that edges look blocky just to save a few kilobytes. - Using a lossless format for a photograph, or a lossy format for a logo with sharp text. - Forgetting that resizing a large image to the dimensions you actually display it at often saves more than compression alone.
Frequently asked questions
Is WebP smaller than JPG and PNG?
Usually yes. At the same visual quality, WebP is around 25–35% smaller than JPG and dramatically smaller than PNG for photos, while still supporting transparency. That makes it one of the most efficient formats for the web.
Do all browsers support WebP?
Every current version of Chrome, Firefox, Safari, and Edge displays WebP. The only place you might hit trouble is very old software or some legacy email clients, in which case JPG or PNG is the safer choice.
Should I compress or resize an image to shrink the file?
They solve the problem differently. Compression lowers the encoding quality so the file is smaller at the same pixel dimensions; resizing reduces the dimensions themselves. If an image is far larger than the space it is shown in, resize it first and then compress — that gives the smallest file with the best on-screen quality.
Is this tool free?
Yes — compressing WebP images here is completely free, with no watermark, no account, and no limit on how many you process.
Will compression change the image dimensions?
No. Compression only changes how the pixels are stored, not the width and height. If you also want smaller dimensions, use the resize tool, which often saves even more space.
