Exact KB

Compress images to an exact file size

Compress JPEG, PNG, WebP, AVIF and more below 50 KB, 100 KB, 250 KB or your own file-size limit. Batch, private and entirely local.

Output strategy

Auto races WebP, AVIF and compatible JPEG after one decode. Hard-edged graphics also enter a palette PNG; photos skip that extra work. The smallest result wins, but a smaller original stays byte-for-byte and transparency is never discarded.

Compression goal
KB

We verify every result. Originals already under the limit are not re-encoded; otherwise an over-limit result is marked and can be resized explicitly.

Resize while compressing

Aspect ratio is always preserved. Every image in a batch is resized independently.

    Everything runs locally. Images never leave this device.

    Meet upload limits without guessing

    Enter the maximum size once. An original already below it stays byte-for-byte; otherwise the background worker tests progressively better quality and keeps the best result that fits.

    A target is a ceiling, not fake precision

    Every result is verified as fitting or over the limit. If quality alone cannot reach an extreme target, use the explicit resize action; the changed pixel dimensions stay visible before download.
