Compress a WebP
Reduce a WebP to a size you specify. Worth checking your file first, though — WebP is already an efficient format, and it may not need this at all.

How it works
- 1
Choose or drag in your WebP files.
- 2
Set the size you want in KB.
- 3
Click Compress and download the result.
Why use this converter
- Produces a universally accepted file
The JPEG output opens where WebP still is not accepted.
- You set the ceiling
Enter the KB you need, if you genuinely need less.
- Transparency handled predictably
WebP supports alpha; those areas become white rather than black.
- Batch friendly
Process a set towards the same target.
When to use it
- Something rejected the WebP: The main honest reason: a tool or platform that will not take it.
- A genuinely oversized WebP: High-resolution files can still exceed a tight budget.
- Legacy platform support: Older systems that predate WebP entirely.
- Handing files to someone else: JPEG travels without questions.
WebP is usually already doing this job
Modern compression techniques let WebP hit noticeably smaller sizes than JPEG for the same visual quality, which is why sites adopted it for page speed in the first place.
So there is less headroom here than with a JPEG or PNG of the same image — the easy savings have already been taken. Compressing a WebP that is already small enough gains little and costs some quality.
The real reason to convert is compatibility
Browsers all handle WebP now, but plenty else does not: older desktop software, some upload forms, various print pipelines, a fair number of mobile apps.
When something refuses the file, converting is the fix — and then the point is producing a JPEG, not making it smaller. Choose a generous target in that case so you keep the quality while solving the actual problem.
Frequently asked questions
Will the output still be WebP?
No, it is a JPEG. That makes it openable where WebP is not accepted, but it may not be smaller, since JPEG is the less efficient format.
Why did my file get bigger?
WebP compresses more efficiently than JPEG, so matching its quality can take more space. If your file already fits your budget, leave it as it is.
What happens to transparency?
Transparent areas are filled with white, because JPEG has no alpha channel.
Should I compress my WebP at all?
Only if it genuinely exceeds a limit, or if something you are uploading to will not accept WebP.
