  1. Select all the PNGs you want to compress.
  2. Choose one setting for the whole batch.
  3. Download them together.

Compressing images one at a time is the part that makes people give up. Select every PNG at once — a whole export folder, a set of screenshots, an icon library — and the same setting is applied consistently across all of them.

More than one file comes back as a single archive, so the download is one click regardless of how many images went in.

Use one setting for a consistent set

When images sit side by side — icons in a toolbar, screenshots through a manual — consistency matters more than squeezing each one to its individual minimum. A single Standard pass across the batch keeps them visually uniform. Reserve per-image tuning for the handful that are genuinely different.

Frequently asked questions

How many PNGs can I compress at once?
Multiple files are supported in a single batch and are returned together. Very large total uploads are capped, so split an enormous folder into a few batches.
Can I use different settings per image?
Not within one batch — a batch applies one setting to everything, which is usually what you want for a consistent set. Run a second batch for images that need different handling.
How do the files come back?
As a single archive when there is more than one, so you only click download once.
