I Built a Free Image to WebP Converter (Because Smallpdf Charges $15/Month)

Description and use

A browser‑based PNG to WebP converter that works offline, requires no signup, and keeps files private.

Problem

Online image-to-WebP converters often limit free usage or require paid subscriptions, and they upload files to remote servers, raising privacy concerns.

Outcome

Users can convert images to WebP locally, free of charge, without uploading files to a server, preserving privacy and avoiding subscription costs.

Workflow

• Open the web tool in a browser
• Drag and drop an image (PNG, JPG, GIF, BMP, SVG)
• Optionally set custom dimensions
• Adjust quality slider (10%–100%)
• Click download to save the .webp file

Evidence

Runs 100% in your browser. No uploads. No accounts. No subscriptions.
