How to use Reduce PNG File Size
- 1. Upload the PNG. Add the file you want to shrink. The tool reads its current metadata and compression state before processing it.
- 2. Let the tool strip and re-compress. It removes non-essential metadata bloat, such as leftover editor tags and unused chunks, and re-compresses the pixel data more efficiently.
- 3. Download the smaller PNG. Save the re-encoded file, such as screenshot.png re-encoded with metadata stripped, once you confirm the visible image is identical but the file is lighter.
When to use Reduce PNG File Size
Reduce PNG File Size strips metadata bloat and re-compresses a PNG to make the file smaller without changing a single visible pixel. Use it as a first pass on any file before it goes onto a page or into a bundle.
- Trimming a screen recording tool's export. Many screenshot and screen-recording apps embed extra editor metadata that adds nothing but file size. Stripping it from screenshot.png cuts weight before attaching it anywhere.
- Lightening assets before a git commit. A repository of design assets accumulates bloated PNGs over time from repeated export cycles. Re-compressing each one before committing keeps the repo lean.
- Meeting an email attachment size limit. A screenshot needs to go out in an email that has a strict attachment size cap. Stripping metadata and re-compressing brings a borderline file comfortably under the limit.
Examples
Slim a screenshot
Input
screenshot.png
Output
screenshot.png re-encoded with metadata stripped
About the Reduce PNG File Size tool
Reduce PNG File Size does its work locally, right in the browser. Strip metadata bloat and re-compress to make PNG files smaller. There is no upload step, no queue and no account, and your data never travels over the network.
It belongs to the PNG Tools collection on EditSafely, a set of 108 small, focused PNG utilities that share the same instant, private workspace.
There is nothing to configure. Provide the input and the result appears on its own. The finished file is put together in browser memory and saved with the Download button, so it never touches a server on the way to your disk. A worked example further down the page shows exactly what the tool produces for a real input.
Running locally also makes the tool fast and dependable: results appear as you type or drop a file, there is no server outage that can take it down mid-task, and confidential data can be processed without a second thought.
