How it Works
Different image formats serve different purposes. PNG supports transparency and is lossless — ideal for graphics and screenshots. JPEG is best for photographs with smaller file sizes. WebP is a modern format that provides excellent compression. AVIF is the newest format with even better compression than WebP. This tool converts between all of these formats entirely in your browser using the HTML5 Canvas API.
100% Secure & Fast
Since the format conversion happens on your local device, we don't store or transmit your images to our server network. Your data stays entirely in your browser memory, offering the fastest and most secure privacy solution possible.
Frequently Asked Questions
Which formats can I convert between?
The tool converts between PNG, JPEG, WebP, and AVIF, with GIF and BMP also accepted as input formats.
Will converting PNG to JPEG lose quality?
JPEG is lossy, so some quality reduction is expected. The tool uses a high default quality setting to minimize visible loss. Converting JPEG to PNG does not restore lost quality — it only changes the container.
Does PNG-to-WebP preserve transparency?
Yes. WebP supports an alpha channel, so PNG files with transparent backgrounds convert cleanly.
Can I batch convert multiple images at once?
Yes. Upload multiple files and convert them all in one go. Each file is processed and available for download separately.
Does the conversion happen on a server?
No. The conversion runs entirely in your browser using the HTML5 Canvas API. No images are uploaded.
