Why convert PNG to WebP?
PNG and WebP handle compression differently — check the comparison below before you convert anything you can't re-export from the original. The main reason to convert PNG to WebP is compatibility: WebP opens in every browser, image viewer and design tool without a plugin, while PNG doesn't always. If you're sharing a file with someone else, sending it to a tool that expects a specific format, or archiving it for the long term, WebP is usually the safer target.
Format comparison
| PNG | WebP | |
|---|---|---|
| Extension | .png | .webp |
| MIME type | image/png | image/webp |
| Compression | lossless compression | either lossy or lossless compression, depending on settings |
| Category | image | image |
Common reasons to convert PNG to WebP
- Uploading to a website builder, ad network or CMS that only accepts WebP
- Shrinking page load time with a more compressible file than the PNG original
- Standardizing on one format so every file behaves the same way in your workflow
Your file, handled carefully
Uploads use TLS in transit and AES-256 SSE-S3 at rest in production (when the production S3 credential gate is enabled), are processed in an isolated job, and deleted on the schedule you choose — as fast as immediately. We don't index, search, or share files between accounts. Read the full security model →
Frequently asked questions
Is converting PNG to WebP free?
Yes — the Free plan includes 50 conversions every month, including PNG to WebP. Paid plans raise that limit.
Will I lose quality converting PNG to WebP?
WebP is modern format with smaller file sizes than jpeg or png at equivalent quality. We use the highest-quality encoder settings by default so visual or data loss is minimized.
Do you keep a copy of my file?
Files are deleted automatically based on your plan's retention options. Free accounts can keep results for 1h or 24h; Pro and above add options such as delete-immediately and 7 days.
What is PNG?
Lossless raster format with alpha transparency, ideal for graphics and screenshots.
Will my converted file have a watermark?
On the Free plan, WebP output includes a small "Converted with Convyx" mark. Pro ($9/mo) removes it, along with the 25 MB file size cap.
What happens if a conversion fails?
You get a clear error message and the job is marked failed in your history — we never silently drop a file. Retry is one click. Monthly quotas count attempts (including failures) because processing starts as soon as the job is created.
