Tune an existing WebP
Run a second, intentional pass when a generated or downloaded WebP is heavier than your delivery budget allows.
Free browser-based WebP tool
Free WebP Compressor
Recompress static WebP images with a quality level you control. Nothing is uploaded to ImageCompressly, and completed files stay in WebP format for immediate download.

Advanced resize settings
Your images stay on your device. Compression happens in your browser.
This version handles static WebP only. Animated WebP is rejected to protect its frames, and a file that is already optimized may show no further reduction.
Modern format, practical control
Why recompress a WebP image?
WebP is often compact already, but an export can still use more quality, metadata, or pixel dimensions than its final placement needs.
Keep the WebP workflow
The file remains WebP, so you can continue using it in a pipeline that already expects that format.
Match display dimensions
Optionally cap the longest side when the source image contains pixels that its final layout will never display.
Measure, then decide
How to compress a WebP online
Because WebP may already be optimized, the best outcome is not always a dramatic percentage. Use the displayed sizes and a visual check to decide whether the new version is useful.
- 01
Add static WebP files
Select or drop one image or a batch. The tool checks the file signature and rejects animations before compression starts.
- 02
Set the target balance
Begin at 80%, then adjust based on the image. Use optional resizing when the source is materially larger than its intended placement.
- 03
Use the measured result
Compare the original and compressed totals. Download only the results that make sense for your quality and size target.
Useful WebP starting points
General web imagery
Start around 80%
A sensible first test for editorial images, cards, and content that mixes detail with broad color areas.
Product detail
Try 85–90%
Preserve more fine texture where close inspection matters, then compare the result at its real display size.
Already optimized
Expect smaller gains
A WebP produced by a modern image pipeline may leave little redundant data for another encoder to remove.
Where smaller WebP files help
Recompression is useful when you inherit an existing WebP and need direct control over its dimensions or quality before delivery.
CMS exports
Check and reduce WebP assets exported by a content system before adding them to a page or campaign.
Design handoffs
Create lighter delivery copies of static WebP visuals while keeping source assets elsewhere.
Website refreshes
Review older WebP files against current layout dimensions and replace only the versions that produce a worthwhile saving.
Frequently asked questions
Important details about recompressing static WebP files.
Can WebP images be compressed again?
Yes. A new quality level or smaller dimensions can reduce some WebP files, although an already optimized image may not become meaningfully smaller.
Does the output stay WebP?
Yes. ImageCompressly preserves the WebP format and does not convert the file to JPG or PNG.
Can I compress animated WebP files?
No. Animated WebP is rejected in this version so the tool never silently turns an animation into a still image.
Why did the tool keep the original WebP size?
If re-encoding would make the file larger and resizing is not needed, ImageCompressly returns the original file instead of giving you a worse size result.
