Frequently Asked Questions

How much can I compress an image without losing quality?+

Most photos can be compressed 40-70% smaller with no visible quality loss using perceptual encoders like mozjpeg and oxipng, which Shrivo uses under the hood.

Can I set a target file size?+

Yes, the smart auto mode lets you target a specific file size in KB and Shrivo finds the best quality setting to hit it.

Does compression happen on a server?+

No, all compression runs locally in your browser via WebAssembly codecs, so your images are never uploaded.

Which formats are supported?+

JPG, PNG, WebP, and AVIF are all supported for both input and output.
