What is an Image to PNG converter?

An Image to PNG converter transforms graphic and photographic files (such as JPG, WEBP, GIF, SVG, BMP, or AVIF) into the Portable Network Graphics (PNG) format compliant with ISO/IEC 15948:2004 for lossless pixel preservation and 8-bit alpha transparency.

Are my images uploaded to an external server or cloud service?

No. ImageToPNG operates completely client-side in your web browser. Your images are processed strictly in your local device memory using native web APIs. No image is ever transmitted, uploaded, copied, or stored on any remote cloud server.

Can I convert JPG to PNG?

Yes. Converting JPG to PNG halts compounding generational quality loss during further image edits and prepares photographic elements for transparent background masking in design tools.

Why is my converted PNG file larger than my original JPG?

JPG uses lossy discrete cosine transform (DCT) quantization which discards subtle color details. PNG uses lossless DEFLATE compression which mathematically preserves every single pixel without approximation.

Image to PNG Converter

Convert any image format—JPG, JPEG, WEBP, GIF, BMP, TIFF, HEIC, AVIF, SVG, ICO, PSD, RAW—to lossless PNG directly in your web browser with zero server uploads.

How to Convert an Image to PNG

Choose Image: Select or drag your source images into the converter.
Browser Processing: Your browser decodes the image locally in memory.
Lossless PNG Encoding: Encodes pixel data using standard DEFLATE compression.
Instant Download: Download individual PNG files or all as a ZIP package.
