Compress WEBP Images Online

Compress WEBP images online without the compression showing

WebP is already efficient — that is the whole reason it exists. Compress it carelessly and the efficiency turns into visible damage: blocky shadows, smudged gradients, skin that looks plastic. This tool runs the compression at a level tuned to stay under that line. The file gets smaller; the picture does not visibly change.

Every image also passes through an adaptive filter that reads each picture and adjusts how hard to smooth it — a busy, detailed photo is treated differently from a flat graphic, instead of both getting the same blunt setting.

Hidden data is removed at the same time

Compressing strips more than bytes. GPS coordinates, camera make and model, and any embedded metadata are removed as part of the process — not as a separate step you have to remember to run. What you download is smaller and carries nothing about where or how the photo was taken.

Transparency survives

A WebP with a transparent background keeps its transparency after compression. The alpha channel is not an afterthought here — it is compressed properly, so a logo or a graphic with soft edges does not come back with a visible seam around the transparent area.

Built for real batches

Upload up to 100 images in one session, each up to 15 MB. Need more? Refresh and start another batch — there is no daily cap forcing you to space it out. This is sized for how people actually use it: a product catalogue, a gallery export, a folder of screenshots, not one image at a time.

Where the size actually goes

Most of a WebP's weight is pixels, not overhead, so most of the saving comes from compressing them efficiently rather than from stripping the file down. Typical photographs shrink substantially with no visible change; images that are already tightly compressed have less room left to give, and that is expected rather than a sign anything went wrong.

Nothing to install, nothing to sign up for

Compression runs in your browser, so it works the same on a phone as on a desktop. There is no account, no watermark and no email step, and files are removed from the server within the hour.

What you get

• Compression tuned to stay below the point where damage becomes visible
• An adaptive filter that treats detailed photos differently from flat graphics
• GPS, camera and embedded metadata stripped automatically
• Transparency preserved, with no seam around the alpha edges
• Up to 100 images per session, 15 MB each, with no daily cap
• Free, with nothing stored for longer than an hour

What's next?

Need a shareable document rather than smaller image files? WebP to PDF turns a whole batch into one PDF that opens anywhere. Working with a mixed folder? Compress PNG and Compress JPG handle the other formats the same way.
