Resize

Resize and compress images

Batch resize images by percentage, maximum edge or bounding box, then compress to the smallest format or an exact KB target — locally and without uploads.

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

75 is a strong web default. The original stays untouched.

Resize while compressing

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

    Everything runs locally. Images never leave this device.

    One decode, two jobs finished

    Reducing pixel dimensions often saves more than lowering quality alone. This workflow resizes each image once in a background worker, then feeds those pixels into the selected encoder or automatic codec race.

    Choose a size that matches delivery

    Use a maximum edge for mixed portrait and landscape batches, a percentage for consistent source sets, or a bounding box for website slots. “Never enlarge” prevents small originals from becoming blurry and heavier.
