Image → WebP / JPEG / PNG Converter
Drop an image and re-encode it as WebP, JPEG or PNG, with a quality control for the lossy formats and an at-a-glance comparison of the original and converted sizes. The work is done by the browser's Canvas, so nothing is uploaded and the file stays on your device. WebP is the usual reason people arrive here: for photographs it lands roughly a quarter to a third smaller than a JPEG of comparable appearance, and unlike JPEG it also supports transparency. Because the image is decoded to pixels and encoded again, the conversion is a fresh encode rather than a repackaging — which is what makes the format choice and the quality setting matter.
Lower = smaller file, more compression artifacts. 80–90 is a typical sweet spot.

How to use
- Drop an image (PNG, JPG, GIF, WebP, AVIF — anything the browser decodes).
- Choose target format and quality (JPEG/WebP only — PNG is lossless).
- Click convert, then download.
Frequently asked questions
- Why WebP?
- Typically 25–35% smaller than JPEG at equivalent quality, with similar browser support in 2026. Good default for web images.
- Does this strip metadata?
- Yes — re-encoding through canvas drops EXIF/ICC. Useful for privacy, problematic if you needed the original color profile.
- Why is the output bigger than the input?
- Re-encoding a lossy file (JPEG → JPEG) at high quality almost always adds bytes. Use a lower quality, or only convert from lossless sources.
- What about AVIF?
- AVIF encode in browsers is still inconsistent (Safari especially). We left it out to avoid silent failures.
- Does converting to WebP lose quality?
- If the source was already lossy, yes - a little. Converting a JPEG to WebP decodes it, including the detail the JPEG already discarded, and encodes it again, so the losses stack. The result usually still looks fine because WebP is more efficient, but converting back and forth repeatedly will visibly degrade an image. Convert once, from the best original you have.
- Why do screenshots and logos look worse than photos?
- Lossy encoders are tuned for the gradual variation of photographs and cope badly with hard edges, flat colour and text, where they produce a faint halo along the boundaries. For that kind of image, raise the quality substantially or keep PNG, which stores sharp edges exactly and is often smaller than a lossy encode of the same content.
- Where might a WebP file not be accepted?
- Browsers have supported it universally for years, so on the web it is safe. The gaps are elsewhere: some desktop image editors, older office software, a few printing services and the occasional upload form still expect JPEG or PNG. If a file is going somewhere other than a web page, converting to JPEG is the more portable choice.
