Will converting from PNG to JPEG keep transparency?

JPEG does not support transparency; transparent areas usually become a solid background (often white). Use PNG or WebP when you need an alpha channel.

Is format conversion lossless?

Moving between lossy formats (JPEG, lossy WebP/AVIF) can introduce new compression. PNG-to-PNG or similar lossless paths preserve pixels; always keep a master file if you need the original quality.

Are files uploaded for conversion?

Conversion runs in your browser using canvas-based encoding, not a remote conversion service.

How It Works

Convert changes image formats—for example JPEG, PNG, WebP, or AVIF—by decoding your file in the browser and encoding it to the format you pick. That workflow runs client-side, which helps when you need WebP for the web, PNG for transparency, or a smaller JPEG for email without handing files to an external converter.

How to Use

Go to the Convert tab and upload your source images.
Pick a default output format (JPEG, PNG, WebP, or AVIF when supported), and optionally override the format per file in the list.
Start conversion and wait for all files to finish.
Download converted files or a ZIP archive for batches.

Common Use Cases

Turning PNG screenshots into smaller JPEGs for sharing.
Producing WebP or AVIF assets for faster websites.
Creating PNG copies when you need transparency from a JPEG original.
Standardizing mixed camera and design exports to one format for a project.
