How to convert images to WebP or AVIF
The flow is built for fast uploads, automatic queued conversion and simple downloads, even when you add images in multiple rounds.
Choose settings
Select WebP or AVIF, choose a quality preset and add resizing if needed.
Conversion starts automatically
Files are queued, and each file status updates live in the table.
Download results
Download images individually or use Download all for the ZIP archive.
FAQ - frequently asked questions
Not automatically. Compare file size and appearance. Simple icons or palette-based PNG files can already be efficient, while large screenshots and transparent photographs often benefit more.
Yes, when the source contains an alpha channel and Keep transparency is enabled. If you disable that option, CloudVertor produces an opaque output.
Yes. Add files in one or more rounds, follow the status of every image and use Download all after the active conversions finish. Invalid files are listed separately and do not prevent successful images from being downloaded.
No. CloudVertor uses temporary server storage for processing and downloads. Files expire automatically, and successfully processed originals can be removed earlier according to the active cleanup policy.
Convert PNG screenshots, graphics and transparent assets to WebP while choosing whether the alpha channel should be kept. The workflow analyzes the image and uses settings appropriate for graphics instead of treating every PNG like a photograph.
Why this conversion is useful
WebP can store both lossy and lossless image data and often reduces large PNG files used on websites. The largest gains usually come from screenshots, exported graphics and oversized assets, while tiny or already optimized PNG files may show limited savings.
Recommended uses
Use this conversion for interface screenshots, product cutouts, illustrations and web graphics. Keep the original PNG when you need a lossless editing source, exact pixel values or compatibility with software that does not support WebP.
Choosing the optimization level
Recommended balances clean edges and size. Maximum quality is useful for text-heavy screenshots or detailed graphics. Images as small as possible is intended for delivery copies where a little additional visual loss is acceptable. Resize only when the target dimensions are known.
Transparency and metadata
WebP supports transparency, so transparent PNG pixels can be retained when Keep transparency is enabled. Disabling it flattens the output. Removing metadata strips ancillary profiles and descriptive information without changing the intended pixel dimensions.
Compatibility and limitations
Flat graphics with very few colors may already be smaller as optimized PNG, and lossy settings can introduce halos around sharp text or transparent edges. Inspect logos and interface captures at their real display size before deployment.
Bulk processing and privacy
Files are validated on the server, queued and processed asynchronously, so a conversion does not keep the upload request open. You can add images in several rounds and download successful results individually or together. Original and converted files are temporary and are removed according to the configured retention policy.
