Is this WEBP to PNG converter really free?

Yes. Up to 5 files at a time, no signup, no catch. The free tier adds a small watermark to image output — Pro ($9.99/mo or $49/yr) removes it, raises the file size limit to 500 MB, and unlocks unlimited batch conversion.

Are my files uploaded to a server?

No — and you can verify it yourself. Open DevTools → Network tab, then convert a file. You'll see zero upload requests. Everything runs in your browser via WebAssembly. We never see your files.

How long does conversion take?

Usually 1–3 seconds for a typical file. The very first conversion on a fresh page load may take 5–20 seconds while the WebAssembly codec loads — after that it's instant. Your CPU does all the work locally.

What is the file size limit?

Free: up to 10 MB per file, 5 files per batch. Pro: up to 500 MB per file, unlimited batch. If you're working with large videos or RAW photos, Pro is built for that.

Can I batch convert multiple WEBP files at once?

Yes — drop multiple files at once (or Ctrl/Cmd+click to select them) and they all convert in parallel. Free accounts handle up to 5 files per batch; Pro has no limit.

Will the image quality change after conversion?

It depends on the formats involved. Converting to a lossless format like PNG preserves every pixel exactly. Converting to a lossy format like JPEG or WebP applies compression — we default to 85% quality, which looks identical to the original for almost all images. You won't notice a difference unless you zoom in pixel-by-pixel.

Do you support batch image conversion?

Yes — drop multiple images at once and they all convert in parallel. Free accounts handle up to 5 at a time; Pro is unlimited. Download everything as a single ZIP when you're done.

How private is this converter?

Completely private — by design, not policy. There is no upload endpoint. Files are processed using WebAssembly inside your browser tab and disappear the moment you close it. We collect only anonymous page-view counts; your file content is never seen or stored.

Why convert WEBP to PNG?

WebP was built for the web. Google designed it to load fast in browsers, and it does that brilliantly — but the moment you try to open a WebP in Photoshop, paste it into a Word doc, upload it to an older CMS, or share it with someone not on a modern browser, things break.

PNG is the universal lossless format. Every image editor, every operating system, every website, and virtually every app supports it natively. When you need an image that just works — everywhere, every time — PNG is the answer.

This conversion is lossless: we decode the WebP and re-encode it as PNG without any quality reduction. The output will be identical to the WebP visually, just in a format the entire world can read.

Common reasons people convert WebP to PNG:

›Right-clicked a Google image or social media photo and got a .webp file that nothing will open
›Need to edit in Photoshop, GIMP, or Figma (all handle PNG natively)
›Uploading to a platform or CMS that doesn't accept WebP yet
›Preserving transparency layers that need to survive format conversion

Quality & file size: WEBP to PNG

Typical file sizes: WEBP 1–3 MB → PNG 8–25 MB.

Both WEBP and PNG use lossy compression. We transcode at high quality settings (equivalent to PNG's recommended web quality) to minimize generational loss.

Color depth: WEBP supports 8-bit, PNG supports 16-bit.

Transparency: WEBP supports transparency. PNG preserves transparency.

Frequently asked questions

Privacy: how FormatDrop handles your files

Your WEBPfiles are converted 100% inside your browser using WebAssembly. They are never uploaded to our servers, never stored, and never seen by anyone other than you. This isn't a privacy policy claim — it's an architectural guarantee: our server has no endpoint that receives file bytes.
