Why convert WebP?

WebP shrinks files by 25–35% vs JPEG, so browsers and platforms adopted it fast — but many upload forms, marketplaces, printers and design tools still reject it. Converting back to PNG keeps your image universally uploadable.

Why convert WebP to PNG?

WebP has become the default output of most browsers and image pipelines because it compresses photos 25–35% smaller than JPEG. But PNG remains the format designers, marketplaces and upload forms rely on when pixels must be exact — logos, transparent stickers, mockups and print files. WebP also stores transparency, but many tools either fail to open it or silently drop the alpha channel. Converting WebP to PNG keeps your original pixel dimensions and your transparency, in a format everything accepts.

How this WebP to PNG converter works

  1. Drop or browse — select a WebP file up to 20 MB.
  2. Local decode — your browser reads the image at its natural size; no scaling is applied and transparency is kept.
  3. One-click download — the PNG keeps your exact pixel dimensions and alpha channel.

Everything happens in your tab — open the network panel and you will see zero upload requests while converting.

WebP to PNG — FAQ

How do I convert WebP to PNG without uploading my image?

Drop your WebP file into the converter above. Your browser decodes it locally and exports a PNG at the exact same pixel dimensions, preserving transparency where the source has it. No file is ever uploaded, so your image stays entirely on your device.

When should I convert WebP to PNG instead of JPG?

Choose PNG when your image has transparency, sharp edges, text or logos — PNG is lossless, so those stay crisp. Choose JPG when file size matters more and the image is a photo. This converter preserves original resolution in both cases, with no upscaling or downscaling.

Does converting WebP to PNG make the file bigger?

Usually yes. PNG is a lossless format, so a WebP photo converted to PNG is typically 2–4× larger than the original WebP. The trade-off is perfect quality and universal compatibility — PNG is accepted by every major platform, marketplace and design tool.

Is this WebP to PNG converter really free?

Yes — completely free, with no watermark, no account, no daily limit and no expiration. All processing runs locally in your browser, so imgsize.cc has no server costs to recover, and there is nothing to charge for.

Need to convert WebP to JPG instead (smaller files for photos)? Or resize images for marketplaces after converting — the same browser-side workflow covers both.
