Universal Image Conversion FAQ
Frequently asked questions about browser-based batch image processing.
Why choose WebPShift over cloud converters like CloudConvert or Convertio?
WebPShift processes 100% of your images locally in your web browser using HTML5 Canvas and multi-threaded Web Workers. No files are ever sent to an external server. You get instantaneous conversion with zero wait queues, unlimited file sizes, no daily caps, and total privacy.
Which image formats can I convert?
WebPShift supports bidirectional conversion between WebP, PNG, and JPG (JPEG) formats. You can convert WebP to PNG (lossless), WebP to JPG, PNG to WebP, JPG to WebP, and PNG to JPG in bulk.
How do I download multiple converted images?
You can download individual images with one click or click the "Download All (ZIP)" button to package the entire converted batch into a single zip file generated directly in your browser memory.
Does WebPShift save or track any of my files?
No. WebPShift is completely stateless. There is no database, no file upload endpoint, no tracking cookies, and no analytics. Your images never leave your local device.
