Slim down WEBP files for a faster site, or make compressed WEBPs straight from JPG and PNG.
Many WEBPs online are exported at high quality and full camera resolution, which defeats the point of the format. This page re-encodes them at a quality you choose and, if you set a max size, scales them to the size your layout actually shows. It also accepts JPG and PNG, so you can go from originals to compressed WEBP in one step. Transparency is kept and everything happens in your browser.
How to use Compress WEBP
- Drop WEBP files, or JPG and PNG originals you want as compressed WEBP.
- Keep quality at 75 for general web images, 80–85 for product photos. Set a max size matching your layout, for example 1200 px.
- Compress and download the WEBPs as files or a ZIP.
What happens to quality, size and metadata
WEBP is lossy here, and re-compressing an already-lossy WEBP adds a second round of loss. At 75 it is rarely visible; check images with fine text or thin lines at 100% zoom. Resizing an oversized image saves more than any quality change.
Transparent areas stay transparent. WEBP output carries no EXIF, so camera details and location are removed. If the result would be bigger than an original WEBP, we keep the original instead. On Safari, which can’t create WEBP itself, a WEBP encoder downloads once.

WEBP WebP is an image format Google released in 2010, documented as RFC 9649. It has a lossy and a lossless mode, transparency and animation, and is usually 25–35% smaller than JPG or PNG at similar quality. Websites use it heavily, but some desktop apps and upload forms still refuse it.

Without this site
Operating systems don’t include a WEBP compressor: Windows Paint and Photos and macOS Preview open WEBP but can’t save it. Website platforms, plugins and image CDNs often re-compress uploads automatically, so check your site’s media settings before doing the work twice. For a private batch of files on your own machine, this page needs no installation, and you can see the before and after size of every file.
Troubleshooting
- Compressing an already small WEBP. Little to gain; we return the original if ours isn’t smaller.
- Soft text in banners. Raise quality to 85–90 for images with lettering.
- Repeated re-encoding. Compress from the original JPG or PNG when you have it, not from an old WEBP.
- Animated WEBP. Only the first frame is kept, so don’t use this page for animations.
Questions and answers
How do I reduce the size of a WEBP file?
Drop it here, set quality to around 75 and, if it is larger than it is displayed, set a max size. Press Compress and compare the sizes shown. Resizing usually gives the biggest saving; quality fine-tunes the rest. Download the new WEBP or a ZIP of many.
Can I compress JPG and PNG to WEBP here?
Yes. This page accepts JPG, PNG and WEBP and always writes WEBP, so converting and compressing happen in a single step. PNGs with transparency keep it, and JPG photos are rotated upright. If you want AVIF instead, or a different output format, use the dedicated converter pages.
What WEBP quality is good for websites?
75–80 suits most page images; 85 for product photos people zoom into; 60–70 for large background images where speed matters more than detail. Pair the setting with a sensible max size, since images bigger than their display size waste far more bytes than a few quality points.
Does compressing WEBP keep transparency?
Yes. WEBP supports an alpha channel, and the compressed file keeps transparent and semi-transparent areas exactly where they were. That makes compressed WEBP a good replacement for heavy transparent PNGs on a website, such as product cut-outs, stickers and banners.
