When you'd do this
You're preparing a mix of images for a website — photos, screenshots, logos, animated GIFs — and want them all in the format that keeps pages light.
What to expect
Photos and illustrations usually come out much smaller as lossy WebP at 80%; screenshots and logos stay sharp with WebP Lossless. Transparency is kept, animated GIFs stay animated, and nothing is enlarged. A WebP can be at most 16,383 px a side, so bigger images are scaled down to fit.
Recommended settings
Lossy at 80% for photos; WebP Lossless for screenshots, logos and pixel art. If you have both kinds, convert and download them in two batches.
Where it opens
Every current browser on every device, WordPress and most site builders. Keep JPG or PNG copies for email and older apps.
Good to know
- HEIC photos (the iPhone's own format) can't be read: on the iPhone, set Settings › Camera › Formats to Most Compatible to take JPGs.
- Animated PNGs give their first frame, and multi-page TIFFs their first page.
- An SVG with no size of its own is drawn 1,024 px on its longest side.
How to do it
- Choose your images, or drop or paste them on the page — any mix of formats.
- Each is set to WebP. Change one on its own row if you like, and set Quality, WebP Lossless and Resize in Settings.
- Convert all, then download each WebP, or all of them in one .zip.
Questions
- Which image formats can I convert to WebP?
- PNG, JPG, JPEG, GIF, TIFF, BMP, AVIF, SVG and ICO — and WebP itself, re-encoded.
- Are animated GIFs kept animated?
- Yes. They become animated WebPs with the same frames, timing and loop count.
- Can I convert different formats at once?
- Yes. Add them together, press Convert all and download the WebPs as one .zip.
