Compress

Get smaller than PNG, with zero quality loss

For when PNG’s own compression ceiling isn’t enough and you still can’t lose any quality. Everything runs in your browser — nothing is uploaded.

PNG’s own compression has a real ceiling, especially on photos — there’s only so much a smarter PNG encoding can do without discarding data. WebP’s lossless mode uses a newer, more efficient method and typically comes out meaningfully smaller than even a well-optimized PNG, for the exact same pixels. The tradeoff: the file is a .webp, not a .png — though since it’s genuinely lossless, it can be converted back to PNG later with zero quality loss either way, if you ever need the .png extension specifically.

Common questions

Is this actually the same quality as PNG, just smaller?
Yes — every pixel in the output is bit-for-bit identical to the input, including in fully transparent areas. WebP’s lossless mode uses newer, more efficient techniques than PNG’s decades-old compression method, which is where the extra savings come from, not from discarding any data.
Why not just use the PNG compressor?
PNG’s compression format has a real ceiling, no matter how well it’s optimized — especially on photographic images. If you need it smaller than PNG’s own best case can offer, while still staying fully lossless, changing the file format is the only honest way to get there.
Will a .webp file work everywhere I need it to?
All modern browsers and most current image editors and platforms support WebP. If you specifically need a .png file later, you can convert this file back — since it’s genuinely lossless, converting back to PNG loses nothing either.
