Compress2PNG is a free, browser-based image compressor. It reduces the size of PNG, JPG, and WebP images entirely on your device — no upload, no watermark, no signup.
Batch-compress images with a live before/after comparison, choose between PNG, JPG, WebP, and AVIF output, and download everything as a ZIP. Every compression runs locally in your browser using the Canvas API.
Everything runs in your browser. Files are never uploaded to a server, never stored, and never tracked. Disconnect your internet after the page loads and the tool still works.
