How to Use PNG to WebP

1

Upload a .png file of up to 10 MB by dropping it on the page or selecting it from your device.

2

Select lossless mode for an identical-looking result, or lossy mode with a quality setting for a much smaller file.

3

Click the Convert button and the image is re-encoded into WebP on the server.

4

Download the .webp output and compare it beside the original PNG before replacing anything in production.

Features

Lossless mode reproduces the PNG pixel for pixel while cutting file size
Alpha channel and transparency carried over intact
Supports PNG files up to 10 MB, including large app screenshots
Side-by-side file size comparison between the source and the result
No sign-up, no watermark and no per-file fees
Server-side encoding works equally well on phone, tablet and desktop

Frequently Asked Questions

Yes. Lossless WebP is mathematically lossless, so every pixel from the source PNG is preserved exactly. The saving comes purely from a more efficient compression method rather than from discarding information.
For typical UI graphics and screenshots, expect a reduction of around 20 to 35 percent at lossless quality. Screenshots containing large blocks of flat colour benefit the most, while busy photographic PNGs benefit less.
Yes, transparency is fully supported and the alpha channel is carried over. Just be aware that transparent pixels still occupy space, so a large transparent canvas will not shrink as dramatically.
Not in practice, because every major browser has supported WebP natively for years. If you must support very old clients, keep the original PNG and use a picture element or a format-detection script to serve it instead.

About PNG to WebP

PNG was invented in 1995 as a lossless format, and for two decades that meant every screenshot, icon and interface asset on the web was stored at four to ten times the size it really needed to be. Lossless WebP fixes that problem: it matches PNG quality pixel for pixel and, on typical UI imagery, still arrives 26 percent smaller.

Use this converter when you have PNGs that are heavy but flat-coloured: dashboard screenshots, product grids, avatars, diagrams, exported design assets. A catalog of two hundred PNGs converted to WebP at lossless quality can free up hundreds of megabytes of bandwidth, and the pixels on screen stay identical.

Uploads up to 10 MB are accepted, and the alpha channel survives the trip, which matters for icons and logos. Pick lossless for a guaranteed-identical result, or step down to lossy when you want a much smaller file and the image is photographic rather than graphic. The choice is on the output panel, so you can try both and compare before committing.

When to Use This Tool

  • Cutting the payload of app screenshots and UI walkthroughs that currently dominate your bundle or page weight
  • Keeping icons and logos pixel-perfect while still making them lighter for a CDN or Git repository
  • Shrinking exported Figma or Sketch assets before dropping them into a front-end build
  • Making sure transparent PNG artwork renders correctly in a WebP pipeline that supports alpha
