WebP is a modern image format that offers better compression than PNG or JPEG for many images. Converting PNG to WebP is useful when portals or websites accept WebP (not all do). This conversion happens in your browser — no servers involved.
When to convert PNG → WebP
- If you need the smallest possible file and the target portal supports WebP.
- If your PNG is photographic (not simple graphics) — WebP gives large savings.
- Keep PNG if you need lossless transparency and the portal requires PNG specifically.
How to convert
- Open Compressly and choose the PNG file.
- Select output = WebP (or Auto which selects WebP when supported).
- Optionally enter a target KB or adjust quality. WebP usually reaches the target at higher quality than JPEG.
- Compress and download the WebP file.
Note: Not all portals accept WebP. If the portal rejects WebP, convert to JPEG instead or
use the original PNG when transparency is required.

FAQ
Q: Will converting to WebP remove transparency?
A: WebP supports transparency (animated or static) with lossless WebP. Choose lossless
WebP if you must preserve exact transparency.
Q: Are WebP files accepted everywhere?
A: No — some older government portals and legacy forms may not accept WebP. If unsure,
use JPG for maximum compatibility.
