Compress images to a target size

Set a maximum size in KB. Compare quality and dimensions before downloading JPEG or WebP.

A few files. A fresh start.

    Maximum, not exact size. 1 KB = 1,000 bytes.

    Off keeps original dimensions. On may reduce the longest edge to 64 px. Check readability.

    JPEG fills transparency; WebP can keep it. Outputs lose metadata and may be larger than the original.

    Quality is searched from 95% down to 10%. A missed target is clearly marked.

    Processed here. Never uploaded.

    Limits & things to know

    Up to 64 MiB of source files per batch and 16 million pixels per image. Large outputs may need a smaller batch.

    Still images only. Re-encoded outputs can be larger. Metadata and original color profiles are not retained. JPEG replaces transparency with the selected background color.

    A smaller file. A clear size limit.

    Check actual bytes and compare details before uploading. Smaller dimensions can meet tighter limits, but may make text unreadable.

    Make your image fit the upload limit

    Choose a maximum file size instead of guessing a quality setting. Review the actual size, dimensions and image before uploading it elsewhere.

    How to use this tool

    1. Choose still JPEG, PNG or WebP images, up to 20 files and 20 MiB each.
    2. Set a target in KB and choose JPEG or WebP. Allow smaller dimensions only if your destination permits them.
    3. Compress, check Target met or Target not met for each result, compare and download individually or as a ZIP.

    A practical example

    For a form requiring a photo below 200 KB, choose 200 KB and JPEG. The tool checks actual encoded bytes. If the original dimensions cannot fit, increase the target or explicitly allow smaller dimensions; always check legibility.

    Frequently asked questions

    Is the output exactly 200 KB?

    No. The target is a maximum: 1 KB = 1,000 bytes. Results may be smaller, and some images cannot reach the limit within the bounded search. The actual bytes and target status are shown.

    Will it shrink dimensions automatically?

    Only when you enable Allow smaller dimensions. The aspect ratio is preserved and images are never enlarged. A bounded search stops at 64 pixels on the longest edge.

    Does it compress PNG losslessly?

    No. PNG input is re-encoded as JPEG or WebP. JPEG fills transparency with the selected color; WebP supports transparency. Lower quality or smaller dimensions loses detail.

    What happens when the target is missed?

    The smallest tried result is offered with Target not met. It is not suitable for that upload limit. Choose a larger target or allow smaller dimensions and retry. Metadata and original color profiles are not retained.
