What happens when I paste an image?
The clipboard may provide PNG instead of the original WebP or AVIF. The queue reports the inspected image MIME, and conversion uses those actual bytes. Color is converted through the browser canvas; HDR and original color profiles are not preserved.
Are my WebP / AVIF files uploaded?
No. BrowserFiles converts the selected files in your browser. File bytes are not sent to a BrowserFiles server.
Can I convert more than one WebP / AVIF file?
Yes. You can select up to 20 WebP, supported AVIF or PNG files and download individual results or a ZIP.
Which WebP and supported AVIF files are accepted?
Still WebP, supported AVIF and PNG files up to 25 MB and 24 megapixels are accepted. Animation and unsupported AVIF layouts are rejected. AVIF decoding depends on your browser; failures stay on this device.
Can I use the converter offline?
Yes, after the route and conversion assets have been cached. The page shows Offline ready when that setup has completed.
Should I choose JPG or PNG?
Auto selects PNG for transparent pixels and JPG for opaque images, separately for each file. Explicit JPG uses a white matte. PNG preserves transparency. AVIF output is unavailable because no encoder has been verified.
What happens to my photo metadata?
Converted outputs have metadata stripped by default. Local history keeps names and result details only; it never keeps file bytes.
What if one file fails?
Each file converts independently. Successful results remain available, while a failed or cancelled file can be retried without stopping the rest of the batch.
