Guide

Good to know

How Arche makes PNG smaller

Arche re-encodes each PNG in the same format and at the same pixel size, keeps transparency, and removes metadata such as EXIF. You only download a result that is smaller than your original; if a file can't be made smaller, Arche tells you and you keep the original.

When PNG is the wrong format

PNG is best for screenshots, logos and graphics with sharp edges or transparency. A photo saved as PNG is usually several times larger than the same photo as JPG or WebP, so convert it with the free PNG to JPG or PNG to WebP tool first, then compress the result.

FAQ

Frequently asked questions

Something else? Write to support@niamori.ai.

Will compressing change how my PNG looks?

The format, pixel size and transparency stay the same. Results look close to the original but are not guaranteed to be bit-identical, so keep your originals if you need the exact pixels.

Does Arche change the format or size of my images?

No. JPEG stays JPEG, PNG stays PNG, and WebP stays WebP, with the same pixel dimensions. Arche recompresses each image and removes metadata such as EXIF location data. Results look close to the original but are not bit-identical.

What if an image cannot be made smaller?

Arche tells you, and you can download the original instead.

How long do you keep my images?

Uploaded images and results are deleted automatically within 48 hours, and you can delete a batch sooner at any time. We process your images only to optimize them and never use them to train models.
