Convert Client Images to WebP Without Uploading Them

Most 'free converters' upload the file. That is a contract problem. This converter encodes in the browser: you can convert unpublished collections, legal-sensitive scans and unreleased products without a third-party disk.

Local encode is the feature

Canvas / WebAssembly runs on the client's machine (or yours). The images never hit our server. That is the workflow you put in a DPA-friendly process.

Why it matters

  • Agencies sign NDAs.
  • Healthcare and legal sites cannot use random SaaS.
  • Even 'we delete in 24 h' is still an upload.

How to do it

  1. Open the converter on your machine.
  2. Drop the client folder. Convert. Inspect savings.
  3. Unlock the ZIP if you need every file. Send via the client's existing drive — still not our server.

Settings that work

Use the quality the brand book implies. When unsure, 80% photos / 90% UI.

Convert a batch in your browser. Nothing is uploaded.

Put it into practice

Frequently asked questions

No. Conversion is in-browser. See the privacy policy.

The API is a different product: images are processed and discarded. The website converter does not upload.
