Are my images uploaded to omgi.'s servers?

Not by default. Local mode keeps files on your device. If you choose server mode, files are processed on our servers and processing artifacts are cleared at session end.

What image formats are supported?

JPG, PNG, and WebP are supported. More formats may be added in the future.

How many images can I compress at once?

Local mode supports up to 100 files per batch, and server mode supports up to 20 files per batch.

Will compression reduce the visible quality of my images?

The compressor reduces file size while preserving as much visual quality as possible. For most images, the difference is not noticeable.

Is there a file size limit per image?

Local mode supports up to 10MB per image. Server mode supports up to 5MB per image.

Can I control the compression level?

A compression quality slider, if available, lets you balance file size and quality.

Do I need an account to compress images?

No. The image compressor is fully usable without any account.
