How WEBP compression works
WEBP is already efficient, so a second pass buys less than it would on a PNG — but there's real room when the original was exported at a high quality setting. Type a target size and Under1MB finds the best quality that fits, keeping transparency intact.
Need to hit an exact number?
Target sizes live on their own pages, where the quality search runs against your limit.
Three things worth knowing about WEBP
Quality is a dial
WEBP lets you trade detail for size, which is where the big savings come from.
Compress from the original
Each lossy pass costs a little detail, so start from the master file rather than a file you already squeezed.
Nothing is uploaded
Your WEBP is decoded and rewritten by the browser. Watch the network tab stay empty.
Questions
Does re-compressing a WEBP hurt it?+
It's a second lossy pass, so stay above roughly quality 70 unless you're chasing a hard limit.
Is transparency kept?+
Yes — alpha survives compression.
Can it get my WEBP under 1 MB?+
Nearly always. If the image is very large in pixels, allow resizing and it will get there comfortably.
Can I compress WEBP files to an exact size?+
Yes — the size pages do that. Pick a limit like 500 KB and we search for the highest quality that fits underneath it.
Are my WEBP files uploaded anywhere?+
No. Compression happens inside your browser, so the file never leaves your device and nothing is stored.
Is EXIF and GPS data removed?+
Yes. Re-encoding writes a clean file without camera, date or location metadata.
