Keep existing transparency in PNG

Check transparency before downloading

PNG keeps existing transparency. It won’t remove a solid background or recover detail lost in the original. Check transparent edges and the exported file size. Your original stays unchanged.

A few useful details

Will converting JPG to PNG remove the background?+

No. It changes the format, not the subject or background. Only transparency already present in the source can be preserved.

Why is the PNG larger than the source?+

PNG can take more space for photographs than lossy formats. Choose it for transparency or format compatibility, not guaranteed size savings.

Will my image keep its quality?+

Save a lossless PNG and keep existing transparency. This won’t remove the background.

Are my files uploaded?+

Non-AI tools process files locally in your browser without uploading them or requiring an account. AI tools use remote processing and are clearly labeled. Files are uploaded only after you explicitly confirm; local tools never switch to cloud processing automatically.
