How Morfile makes your PNG files lighter

Morfile reduces the number of colours where it doesn’t show, then reorganises the file without losing anything. Screenshots and logos gain the most.

Aim for an exact size

In the app, choose a target size: under 1, 2, 5, 10 or 25 MB, or any value you like. Morfile finds the best quality that fits, and tells you clearly if it can’t be done.

Frequently asked questions

Is it free to compress a PNG file?

Yes, with automatic compression, up to 5 MB and one file at a time, no sign-up. With Morfile Pro: batches, big files and target size.

Is my PNG file uploaded to a server?

No. Compression happens in your browser, on your device. Even a big video is processed with no upload time.

Will I lose quality?

Light compression is invisible. Strong makes the file as light as possible, with a loss you can see up close. For images, a slider compares before and after.

How do I get under an email size limit?

In the app, choose the “under 25 MB” target size (Gmail, Outlook) or “under 10 MB” for stricter mail services. Morfile does the rest.
