Frequently asked questions
Is it safe to convert PNG to WebP online?+
With EditItAll, your files are never uploaded: decoding and encoding run inside your browser using WebAssembly (Squoosh-grade codecs (MozJPEG, libwebp, libavif, libjxl, OxiPNG) to decode, Squoosh-grade codecs (MozJPEG, libwebp, libavif, libjxl, OxiPNG) to encode). The images stay on your device from start to finish, and the whole thing works offline once the page has loaded.
Will converting PNG to WebP lose quality?+
WebP supports both lossy and lossless modes. At the default settings EditItAll uses visually transparent quality; push the slider to 100 for lossless where supported.
Is there a file size or count limit?+
No hard limits and no accounts — processing uses your own device's memory and CPU, so very large images are only constrained by your browser (multi-hundred-megapixel images may fail on low-memory devices). Batch as many files as you like; they are processed in sequence.
Can I convert WebP back to PNG?+
Yes — use the WebP to PNG converter, or just change the output format dropdown after dropping files.
