Which image formats are supported?

We support JPEG, PNG, and WebP. You can also convert JPG or PNG files to WebP format for even better compression ratios.

Will I lose quality when I compress images?

We use smart lossy algorithms that reduce file size by stripping data invisible to the human eye. Most users see no visible difference even at 60–70% compression.

Is there a file size limit for bulk uploads?

You can upload up to 50 images at once, with each file up to 50 MB — more than enough for professional photography workflows.

What does 'Convert to WebP' do?

WebP is a modern image format developed by Google that achieves 25–35% smaller files than JPEG at the same visual quality. Enabling this option re-encodes your images to WebP.
