WebP beats both JPG and PNG on size while supporting transparency, making it ideal for fast sites. This tool converts your JPG or PNG into an optimised WebP for the smallest delivery.

One format that does the job of two

For years you had to pick a side: JPG for small photos or PNG for transparency. WebP lets you stop choosing. It compresses photographs about as well as JPG while also carrying a full alpha channel like PNG, so a single modern format covers a colour photo, a flat logo, and a transparent overlay alike. Convert a photo and it tends to land 25-35% lighter than the JPG; convert a transparent graphic and it can be a fraction of the PNG. For a website that means fewer formats to manage and a faster page from the same set of images. This converter takes your JPG or PNG and re-encodes it into an optimised WebP that looks the same at normal viewing sizes but weighs noticeably less.

JPG or PNG in — what to expect

The converter handles either input and treats each the right way. A few things worth knowing before you upload:

  • Photos (JPG): re-encoded into WebP's lossy mode for a smaller, equally sharp result.
  • Graphics (PNG): transparency carries straight across, and complex graphics often shrink dramatically.
  • Already-compressed sources: WebP still trims bytes, but it can't restore detail an earlier save removed.

If your PNG is really a photo in disguise, the conversion to WebP will be one of the biggest savings you'll see anywhere on the site.

Where WebP fits with the other tools

WebP is the lightweight delivery format; the rest of the toolkit feeds it. If an image is larger on screen than it needs to be, scale it down first with the resizer so you aren't converting pixels nobody sees. If you still want a plain JPG — for an email or an older system that won't read WebP — make one with image compression and serve it as a fallback. And when transparency matters but you need a PNG backup too, PNG optimisation handles that. It all lives together on tinyimgcompress, so building a small family of formats for one picture is just a few uploads.

Frequently asked questions

Is WebP really smaller than JPG?
Yes, typically 25-35% smaller at the same visible quality, and smaller than PNG too. That's why it's the go-to format for fast-loading websites.
Does WebP keep transparency?
Yes. WebP supports a full alpha channel, so transparency from a PNG converts across cleanly without any loss.
Can I convert both photos and graphics?
Both. Photos get a solid size cut versus JPG, while complex graphics with transparency often shrink dramatically compared with PNG.
Will converting improve a low-quality image?
No. Conversion can't add back detail an earlier save removed. It re-packs the existing picture into a smaller file at the same quality.
