Will the result be exactly {size}?

The result lands at or just under {size}. Reaching the byte value exactly is not possible with image encoders, so the tool targets the closest size that does not exceed your limit.

Does quality drop a lot?

Only as much as needed. The search starts at high quality and lowers it step by step, stopping as soon as the file fits the target.

Which formats can I use?

JPG, PNG and WebP as input and output. WebP usually reaches small targets with the best quality.

Are my images uploaded?

No. Decoding, compressing and downloading all happen locally in your browser.

Frequently asked questions

How to compress an image to 20 KB

Upload portals often reject anything above a fixed file size. Instead of exporting again and again, set the target once: the compressor repeatedly re-encodes the image and narrows in on the best quality that stays within 20 KB. JPG, PNG and WebP are supported, the result is shown with its real byte size before you download, and no file is ever sent to a server.
