WEBP Compressor
WEBP's compression usually beats JPEG at the same visual quality. Drop a WEBP file below and drag the quality slider until the size looks right.

Frequently asked questions
How much smaller will my WEBP get?+
It depends on the source image and the quality you pick — photographic images with lots of detail compress less than simple graphics. Try 70–80% quality as a starting point.
Does compressing change the image dimensions?+
No — this tool only affects file size and visual quality, never the pixel dimensions. Use the Resize tool if you also want smaller dimensions.
Is this a lossy or lossless process?+
Lossy — you're trading a small amount of visual quality for a smaller file, controlled entirely by the quality slider.
Is there a maximum file size?+
There's no fixed upload limit — Orbfile isn't uploading anything. The practical ceiling is your device's own memory, which comfortably handles even large, high-resolution photos.
How do I compress a WEBP?+
Drop your WEBP into the box above and drag the quality slider — the estimated output size updates live, and your download is ready the moment you're happy with the tradeoff.
About WEBP
What is WEBP?
WEBP is Google's web-focused image format, offering both lossy and lossless modes plus transparency in one file type.

How it works
- 1
Drop your file in
Drag your image onto the box above, or click it to browse — there's no account to create and no upload to wait on.
- 2
Adjust the slider
Drag the quality slider and watch the estimated file size update in real time.

Download the result
Your browser processes everything locally and hands you a download link the moment it's done — nothing was ever sent to a server.
Is it private?
Everything happens locally, inside this browser tab. Your image is read from disk, processed with WebAssembly running on your own device, and handed back to you as a download — it's never transmitted anywhere, so there's nothing to intercept and nothing stored on a server.
Common use cases
- Web pages that want faster load times
- Replacing PNG for graphics with transparency
- Preparing images for a website or online store
- Attaching a photo to an email with a size limit

About WEBP files+
WEBP is Google's web-focused image format, offering both lossy and lossless modes plus transparency in one file type.
Google introduced WebP in 2010 to tackle a specific problem: the average web page was (and still is) dominated by image weight, and neither JPEG nor PNG alone could losslessly compete on both photos and graphics. WebP borrows compression techniques from video codecs to squeeze photographic images noticeably smaller than JPEG at the same visual quality, while its lossless mode competes with PNG for graphics — all while still supporting transparency and even simple animation in one container. Adoption was slow at first, but every major browser now supports it natively, which is why so many websites quietly serve WebP images today to cut load times.
How to open a WEBP file
Opens readily in Any modern web browser, Windows Photos and macOS Preview (recent versions). For real editing, use GIMP, Affinity Photo, Photoshop (with a plugin on older versions).
Good for
- typically 25–35% smaller than JPG at equal quality
- supports transparency like PNG
- supported by every modern browser
Watch out for
- a handful of older tools and legacy CMSes still don't open it directly
