    Aspect-safe by default

    Predictable resizing without hidden uploads

    Fit or exact

    Fit mode keeps the original aspect ratio inside a bounding box. Exact mode uses both requested dimensions and may change the aspect ratio.

    Batch without memory spikes

    Files are decoded and encoded sequentially. Batch results are written into a local ZIP rather than keeping every decoded image alive.

    No accidental enlargement

    Smaller images remain at their original dimensions unless you explicitly allow upscaling.

    New privacy-safe derivative

    The export is newly encoded and does not copy embedded metadata. The selected source file is never mutated.

    Image resizing questions

    Can I resize multiple images?

    Yes. Choose up to 50 supported images and download a local ZIP of successful derivatives.

    Which format should I use?

    JPEG suits photographs, PNG suits lossless graphics and transparency, and WebP often produces smaller web images.

    Need to crop or rotate?

    Use the complete image editor for crop selection, rotation and flipping.
