About this tool
PNG is a lossless format, so converting a JPG to PNG stops further quality loss when you plan to edit and re-save an image repeatedly, and it gives you a format that supports transparency if you later add it. It is also the format some tools and pipelines specifically require.
Drop one or many JPGs and each is re-encoded as PNG in your browser. Note that converting does not recover detail the original JPG already discarded — it simply stores the current pixels losslessly. Download the results individually or as a ZIP, all without uploading anything.
Conversion runs locally in your browser — nothing is uploaded.
Frequently asked questions
Does converting JPG to PNG improve quality?
No — it cannot restore detail the JPG already lost. It does prevent additional loss on future edits, since PNG is lossless.
Will the PNG be larger than the JPG?
Usually yes, especially for photos, because PNG is lossless. That is expected; PNG trades size for no further quality loss.
Can I batch-convert?
Yes — drop multiple files and download them individually or as one ZIP.
