Shrinkrs / Compress images
Compress WebP images online
Shrink existing WebP files, or convert JPG and PNG images to WebP to cut their size. Set the quality yourself and see the saving for every file.
No image handy?
For PNG, quality sets how many colours are kept. 100 keeps them all and 60 to 80 suits most graphics. Photos may need a higher setting to avoid banding.
How to use the Compress WebP tool
- STEP 1
Add WebP, JPG or PNG files
Existing WebP files are re-compressed. JPG and PNG files are converted to WebP.
- STEP 2
Pick a quality
75 is a safe default. WebP at 75 usually looks as good as a JPEG at 85 and is smaller.
- STEP 3
Download
Save single files or the whole batch as a ZIP.
Why WebP files are smaller
WebP was designed for the web and typically produces files 25 to 35 percent smaller than JPEG at similar visual quality. It also supports transparency, so it can replace PNG for logos and cut-outs. Every current major browser can display it.
Compressing a WebP file that is already small gives diminishing returns. The largest savings come from WebP files exported at a very high quality, or from converting JPG and PNG originals to WebP for the first time.
Lossy WebP and what to expect
Shrinkrs writes lossy WebP. Quality 75 to 80 is a good balance for photos. For screenshots with sharp text, go to 85 or higher, because lossy compression softens fine edges first.
If your browser cannot create WebP files, which can happen on older versions of Safari, Shrinkrs says so and saves a JPEG instead of failing silently.
Questions people ask
Can I convert JPG or PNG to WebP here?
Yes. Add the JPG or PNG files and keep the output format on WebP. Transparency in PNG files is preserved.
Does WebP work everywhere?
It works in all current browsers and in most modern apps. Some older desktop software and a few upload forms still reject it. If a site refuses a WebP file, convert it to JPG with the WebP to JPG tool.
Are animated WebP files supported?
No. Only the first frame of an animated WebP is processed, and the result is a still image.
Is my image sent to a server?
No. Compression runs in your browser on your device.
