Frequently Asked Questions

Which formats are supported?

Input: JPEG, PNG, WebP, GIF, BMP, SVG, and AVIF. Output: JPEG, PNG, and WebP. AVIF output depends on browser support (Chrome 85+, Firefox 93+).

Does conversion reduce quality?

Converting to lossless formats (PNG) preserves full quality. Converting to lossy formats (JPEG, WebP) lets you adjust the quality slider - higher quality means larger files. Converting from lossy to lossless doesn't restore lost quality.

Why use WebP over JPEG?

WebP typically produces 25-35% smaller files than JPEG at the same visual quality. It also supports transparency (like PNG) and animation (like GIF). It's supported by all modern browsers.

How do I convert WebP to PNG?

Upload the WebP file, choose PNG as the output format, then download. Transparency is preserved because PNG supports an alpha channel, and the file is processed entirely in your browser.

Are my images uploaded to a server?

No. Conversion runs locally in your browser using the Canvas API, so the image data never leaves your device. This makes it safe for private or unreleased graphics.
