Why convert images to WEBP here?

Any image format in

JPG from your camera, PNG from a screenshot, HEIC from your iPhone, AVIF, TIFF from a scanner, BMP, GIF, SVG, ICO — if it's an image, this converter handles it. One output format to rule them all: WEBP.

Your files stay private

Conversion runs entirely in your browser. Nothing gets uploaded to a server, so there's no retention, no logging, and nothing to leak.

Batch up to 30 images

Drop a whole folder of mixed formats at once. Each file gets its own .webp, and you can grab the whole batch as a single ZIP.

Smaller than JPG, sharper than PNG

WEBP typically produces files 25–35% smaller than the equivalent JPG at the same perceived quality, and handles transparency better than PNG without the size penalty.

Transparency preserved

WEBP supports alpha channels. Transparent areas in your source — from PNG, HEIC, SVG, or another WEBP — come through untouched in the output.

Free, no strings attached

No subscription, no watermark, no daily limit. Convert as many images as you need, as often as you need.

Sometimes you just need a smaller, sharper image

A landing page that finally passed the Lighthouse audit

You're shipping a landing page on Friday and Lighthouse keeps flagging your hero image. The PNG you exported from Figma is 2.4 MB and the page weight is killing your Largest Contentful Paint score. The marketing team picked the image, you don't have time to renegotiate.

You drop the PNG into the converter, leave quality on the default 85, and get back a 380 KB WEBP that looks identical at hero size. You swap the asset, push the change, and Lighthouse goes from 67 to 94 on performance. The marketing team never noticed the difference visually.

Six MB of hero images on the site became 1.1 MB total. Same look, faster load.

A logo set the brand book wanted in WEBP

Your client updated their brand guidelines and now requires WEBP for all web assets — they read somewhere it was the right call. You have thirty PNG logos with transparent backgrounds, and the brand book wants them as WEBP without losing the alpha channel.

You drop all thirty PNGs into the converter, set quality to Max so the logos stay crisp, and get back thirty WEBPs with transparency intact. Each one is roughly half the size of the original PNG. The client signs off without revisions.

What you appreciate is that the alpha channel just worked — no flattening, no halos, no need to re-export from the source files.

A blog archive of JPGs that needed to fit in a CDN tier

You moved your blog to a static hosting plan with a generous-but-not-infinite CDN tier. Your image archive is six years of JPGs and you're 200 MB over the free quota. You'd rather not pay for the next tier just to host old hero images.

You batch-convert the largest 200 JPGs to WEBP at quality 80, swap the references in your build script, and the total drops to 35% of the original size. You're back under the quota with room to spare, and the visual difference on a blog post is invisible to readers.

Same archive, smaller bill, no quality complaints.
