Frequently asked questions
Does WebP support transparency?
Yes. Unlike JPG, WebP supports alpha channels, so converting transparent PNG to WebP keeps the transparency.
Should I use lossy or lossless WebP?
This tool uses lossy WebP at 92% quality, which is visually indistinguishable from the original but much smaller. For pixel-perfect lossless conversion, stay with PNG.
Are my files really not uploaded?
Correct. Every conversion in this tool runs in your browser using JavaScript and the local file APIs. There is no server-side processing, no file upload, no temporary storage, and no log of what you converted. You can verify this by opening your browser's network tab while converting — the only traffic is loading the page itself.
Do I need an account or to install anything?
No. Open the page, drop your file, download the result. No signup, no email, no extension, no app.
Is there a file-size limit?
Not from us. The practical limit is your device's memory — browser tabs typically handle files in the hundreds of megabytes range without issues. Very large files may take longer to process on phones than on laptops.
