How to convert PNG to JPG in bulk in three steps

PNG is lossless, which is exactly why a folder of screenshots gets so heavy. This bulk PNG to JPG converter rewrites the whole batch as compact JPG files, and every step happens right inside your browser.

  1. 01

    Add your PNG files

    Drag a whole folder onto the tool, or click to browse and pick the files you want to convert. PNG to JPG is the default here, but the batch can also contain WebP or GIF frames — nothing is uploaded anywhere.

  2. 02

    Pick a quality level

    JPG is already selected as the output format. Drag the single quality slider and that one setting applies to the whole batch, so you convert PNG to JPG in bulk with consistent results instead of exporting each file by hand.

  3. 03

    Download the JPG files

    Press process and the tool will convert PNG to JPG in bulk locally, showing the new size and the percentage saved on each one. Download a single result or grab the entire batch as a ZIP.

A bulk PNG to JPG converter built to cut real weight

Stop re-exporting one screenshot at a time. Set the quality once, then convert PNG to JPG in bulk so a folder that would not fit in an email ships as a fraction of the size.

One slider, every file

Choose the quality once and the tool reuses it across the batch. That is the point of a bulk PNG to JPG converter: you convert PNG to JPG in bulk with a single decision instead of repeating the same export dozens of times.

Built for screenshots

Screenshots, UI exports, and design mockups are usually saved as PNG and are usually far heavier than they need to be. Convert PNG to JPG in bulk and the same images become easy to email, attach, or upload.

Private by design

This converter runs entirely in your browser with the Canvas API. Your images are never uploaded to a server, so you can convert PNG to JPG in bulk even when the files are private, sensitive, or unreleased.

Who converts PNG to JPG every single week

Anyone who works with screenshots or exports ends up needing to convert PNG to JPG in bulk, simply because JPG is the format everything else expects.
