I Built a Free Batch Image Format Converter (Because Convertio Charges $25/Month)

Description and use

A browser-based tool lets users batch convert PNG, JPG, and WebP images for free and privately, without uploading to a server.

Problem

Convertio’s free tier limits users to two files at a time and charges $25/month for batch conversion, making it impractical for bulk image format changes.

Outcome

Users can convert large batches of images locally for free, preserving privacy and eliminating subscription costs.

Workflow

• Open the tool in a browser
• Drag and drop images into the interface
• Select desired output format (PNG, JPG, or WebP)
• Click convert
• Download the resulting ZIP file

Evidence

Batch Image Format Converter runs 100% in your browser. No uploads. No accounts. No subscriptions.
