Batch JPG to PNG Converter

Convert a whole folder of JPG files to PNG and download them as one ZIP archive.

How to use the Batch JPG to PNG Converter

  1. Select every JPG file you want to convert, or drop the whole selection at once.
  2. Adjust the quality if the option is shown.
  3. Press Convert and wait for the batch to finish.
  4. Press Download all as ZIP.

Converting a set of files in one pass

Each file is decoded and written out as PNG in turn, keeping its original name and dimensions and changing only the extension. The results appear as they are finished, so you can start downloading before the whole batch completes.

JPG to PNG in short

PNG stores images without losing a single pixel and supports a full alpha channel, so transparent areas stay transparent.

Practical limits

Processing happens one image at a time inside the browser tab, so a batch of very large photographs takes a while and uses memory. If a job stalls, split it into smaller groups. The ZIP archive is assembled without extra compression, since the images inside are already compressed.

Frequently asked questions

Are the file names preserved?
Yes. Only the extension changes.
How many files can I add?
There is no fixed limit, but the practical ceiling depends on your device's memory. Twenty to fifty photographs at a time is comfortable on most machines.
