About

WEBP

WebP is a modern image format developed by Google, supporting both lossy and lossless compression plus an Alpha channel. Compared to JPEG/PNG, WebP produces smaller files at equivalent quality — ideal for efficient web transfer of raster tiles and map imagery.

Conversion trade-offs

WEBP: what you gain

  • Most efficient for web transfer
  • Balances quality and size

Why convert ERS to WEBP?

Converting ERS to WEBP is one of the most common workflows in GIS. ERS data usually comes from desktop GIS software, government open-data portals, or data exchange with partners, while WEBP is what modern tools, web maps, and platforms expect. This converter bridges the two: it reads your ERS files, keeps geometry and attributes intact, and writes clean WEBP output — entirely in your browser, so your data never leaves your device.

Frequently asked questions

Are my files uploaded to a server?

No. The conversion runs entirely in your browser using WebAssembly — your files never leave your device.

Is the ERS to WEBP converter free?

Yes, completely free with no sign-up and no usage limits.

Are coordinate systems preserved when converting ERS to WEBP?

By default the output keeps the source coordinate system. If your ERS file uses a projected CRS (like UTM), you can search any EPSG coordinate system by keyword or code and reproject in one step. Note: output formats that require WGS84 by specification (KML, KMZ, GPX) always reproject to WGS84 automatically.

Can I convert multiple files at once?

Yes — drop several ERS files at once and each one produces its own WEBP output.
