Convert JPG/PNG to WebP for Faster Landing Pages

A 4 MB hero photo is an LCP tax. Modern browsers handle WebP well for site content. Email and some CMSs still prefer JPG — convert with intent, not blindly.

Resize, then convert

Set display width on /tool/resize-image (for example 1600px for a blog hero). Then convert with /tool/jpg-to-webp or /tool/png-to-webp. Keep the original master.

Need JPG again?

/tool/webp-to-jpg flattens transparency to white. Prefer /tool/webp-to-png when alpha matters.

Privacy

These converters run in the browser canvas, which matters when brand assets shouldn’t hit a random online compressor.

Not for scan packets

For paperwork photos headed to a portal, use JPG→PDF and compress — not WebP.

Where WebP helps, and where it does not

Use it for images that are part of a web page: heroes, blog figures, product shots. The win shows up in page weight, not in an email attachment. Many inboxes and older office tools still display WebP poorly or not at all, so a client who asked for “the photo” should get JPG or PNG. Resize to the width the layout actually uses before you convert. A 4000-pixel WebP of a 800-pixel column is still too big. Keep the master JPG or PNG. If you later need transparency, PNG or a WebP that you convert back to PNG is the path — converting to JPG paints transparent pixels white. Check the CMS: some builders recompress uploads and throw away the file you carefully made. If the published image looks softer than your export, the CMS is the next place to look, not another conversion pass.
