WebP is a modern image format from Google that delivers high‑quality
pictures at smaller file sizes than PNG or JPEG. It supports both
lossy and lossless compression, plus transparency (alpha) and
animation. Smaller images mean faster pages, better Core Web Vitals,
and improved SEO.
Why switch from PNG/JPEG?
30–70% smaller files at visually identical quality in
typical web scenarios.
Alpha transparency like PNG, but with compression closer to
JPEG.
Animation support as a GIF alternative with far smaller
sizes.
Privacy: how we handle your files
Your images are processed in‑browser using the Canvas API—no
server upload. Nothing is stored on our servers. Close the tab and
your files are gone.
Tips for best results
Start around 75–85 quality for photos;
90–100 lossless for UI assets/logos.
Resize large images to the display size before converting for
maximal savings.
Use animated WebP to replace heavy GIFs.
FAQ
Will WebP work everywhere? Yes—modern browsers support it. We
fall back to PNG/JPEG for legacy contexts.
Is the converter free? Yes—no watermarks, no quotas.
What is WebP and when should you use it?
WebP is a modern image format from Google that can
shrink file sizes by 20–40% compared to PNG or JPG at similar quality.
Smaller images load faster and improve Core Web Vitals.
PNG vs WebP at a glance
Transparency: Both support alpha transparency
(including soft edges).
Lossless option: Use PNG or
lossless WebP for pixel-perfect UI sprites, logos, and
diagrams.
Photos/illustrations: WebP (quality ~85–92) is
usually much smaller with no visible drop in quality.
Browser support: All modern browsers support WebP.
Quick tips
Starting quality: Try 90; if the file is still
large, test 85–88.
Round‑tripping: Converting PNG → WebP (lossy) → PNG
won’t restore the original detail. Keep a master PNG if needed.
