🪄 Ways to Use It

Paste into documents & Office files

Saved an image that turned out to be WebP? Convert it back to PNG or JPEG in one click.

Submit where WebP isn't accepted

Print shops, social platforms, legacy systems — deliver images in a format they take.

Transparent PNG → white JPEG

You choose the background color explicitly, so no more surprise black backgrounds.

Normalize a mixed batch

Mixed PNG / JPEG / WebP files? Convert them all to one format in a single run.

🔒 Privacy

Your images are never uploaded — conversion happens entirely in your browser. Re-encoding through canvas also strips EXIF metadata such as location data automatically.

❓ FAQ

Can I convert WebP to PNG?

Yes. Select PNG as the output format and convert. JPEG and WebP outputs work the same way.

Are my images uploaded?

No. Conversion runs entirely in your browser via canvas; image data never leaves your device.

What happens to transparency?

PNG / WebP output keeps transparency. JPEG can't, so transparent areas are filled with your chosen background color (white, black or custom).

How many files at once?

There's no fixed limit — it depends on your device's memory. Very large images are automatically downscaled to a safe size.

How to use

STEP 1

Choose PNG, JPEG or WebP. For JPEG / WebP you can set quality, and optionally resize.

STEP 3

Convert & download

Hit Convert to process everything. Download files individually or all at once.

  • JPEG can't keep transparency — transparent areas are filled with the background color you choose.
  • PNG is lossless, so converted files can be larger than the original.
  • Images are processed entirely in your browser and never sent anywhere.
