WebP supports both lossy and lossless compression and can include transparency. When accepted by the receiving system, WebP will usually give you the smallest file size for photos and screenshots.
WebP advantages
- - Better compression efficiency compared to JPEG at similar perceived quality.
- - Supports transparency (like PNG) with smaller sizes.
- - Can reduce bandwidth and upload time for modern portals.
When not to use WebP
- - If the portal explicitly rejects WebP (many older government portals do).
- - If you need guaranteed compatibility with old browsers (rare today but possible).
How to compress WebP with Compressly
- Open Compressly and choose a WebP file, or use Auto format to produce WebP when supported.
- Set a Target (KB) value and press Compress. WebP usually reaches the target at better visible quality than JPEG.
- If you need lossless transparency, select WebP and use a higher quality / lossless option if available.
Note - always check portal acceptance. If unsure, create two files: WebP for fast modern systems and JPEG
for maximum compatibility.
