    Built for privacy

    Image data is processed in your web browser and not sent to BriskFiles servers. The HEIC decoder is served by BriskFiles when needed, and selected images are decoded locally.

    Works without an account

    No signup or watermark. JPG and WebP are lossy formats, while PNG is lossless. Repeated conversions may reduce quality, so keep your originals.

    Supported formats and limits

    JPG / PNG / WebP → JPG / WebP. Target KB is best effort and may reduce dimensions. JPG output loses transparency; use WebP output when transparency matters.

    Up to 20 files per batch, 25 MB per file and 150 MB combined; decoded images up to 36 megapixels. Large batches may exceed device memory.

    Troubleshooting

    If an image will not open, check its actual format and try a smaller file. For HEIC, allow the decoder to finish loading and retry if the connection fails. Keep your original files and inspect the download before sharing.

    Frequently asked questions

    Is the target KB size guaranteed?

    No. The tool tries smaller quality and dimensions. Check the actual downloaded size and readability before submitting a file.
