Good to know

The JPG to PNG converter converts up to 20 JPG images at once directly in your browser via canvas, losslessly to PNG, with no quality slider since PNG as the target format is always compressed losslessly. Each file can be up to 50 MB, up to 300 MB total per batch.

Multiple results can be downloaded together as a ZIP, with a visible size comparison per file. Important: PNG often makes photos larger and does not restore details already lost through lossy JPG compression.

Typical use cases

Prepare a photo for lossless further editing

Convert a JPG to PNG before saving it repeatedly in an image editor, to avoid further compression loss on each save.

Batch-convert multiple JPG photos to PNG

Select up to 20 JPG files at once and download the results together as a ZIP.

Tips for better results

Plan for larger files

Since PNG compresses losslessly, the file usually becomes significantly larger than the original JPG for photos.

Don't expect lost detail to return

The conversion does not undo the JPG compression result — image details already lost stay lost.
