PNG Converter
Convert images to PNG format with lossless compression and optional resize.
Convert JPG, WebP, AVIF, BMP, TIFF, or GIF images to PNG with lossless compression. PNG preserves every pixel and supports transparency, making it ideal for screenshots, logos, illustrations, and graphics with sharp edges or text. All conversion runs entirely in your browser inside a Web Worker, so your images never leave your device. Optional max-width resize lets you shrink output dimensions while keeping the aspect ratio.

FAQ
Common questions and answers about this topic.
Are my images uploaded to a server?
No. All conversion runs entirely in your browser inside a Web Worker. Your images never leave your device, ensuring complete privacy.
When should I use PNG instead of JPG?
Use PNG for screenshots, logos, line art, illustrations, and any image with sharp edges, text, or transparency. JPG is better for photographs since it compresses smoother gradients more efficiently with lossy compression.
Will transparency be preserved?
Yes. PNG fully supports an alpha channel, so transparent regions in WebP, AVIF, or original PNG inputs are preserved in the output. Inputs without alpha (such as JPG or BMP) will simply produce an opaque PNG.
