    Free Image Compressor

    Free compression that never uploads your photo. Dial quality while you watch the preview, then download the smaller file. Useful before posting or emailing when a platform rejects a large original.

    Same quality bar. Still free. Still no upload.

    Your files never leave your device

    Free to use, with no account, no usage limit and no watermark, because the work runs on your device rather than on our servers.

    This is not a promise about how carefully we handle your upload. There is no upload. The file you choose is read into memory by your own browser, processed there, and handed back as a download — the tool has no server component and makes no network request with your data.

    • Nothing is stored. We never receive the file, so there is no copy to retain, no retention period to disclose, and nothing to delete on request.
    • Nothing is transmitted. No upload endpoint, no analytics payload carrying file contents, no third-party processor.
    • You can verify it. Load this page, disconnect from the internet, and use the tool. It still works, because everything it needs is already on your machine.
    • Nothing persists after you close the tab. Files are held in page memory only — not in local storage, not in a cache, not in a database.

    A note on wording, because it matters: we do not describe these tools as “encrypted.” Encryption protects data that travels to somebody else's computer. Your file does not travel, so there is nothing to encrypt and nothing to intercept — which is a stronger guarantee than encryption, not a weaker one. The page itself is served over HTTPS like the rest of the site.

    This makes the tools safe for material you are contractually barred from uploading to third-party services — client footage under NDA, unreleased campaign assets, anything covered by a confidentiality clause.

    How it works

    1. 1. Drop an image

      Large PNG or JPEG is fine. It never leaves the tab.

    2. 2. Choose a quality target

      Balance visual quality against file weight.

    3. 3. Download the smaller file

      Compare before and after on your device.

    Questions

    How much can I compress before it looks bad?

    For photographs, quality around 0.7-0.8 usually removes more than half the file size with no difference most viewers would notice. Flat artwork, screenshots and anything with text degrade much earlier, because JPEG-style compression puts its artifacts exactly on hard edges. Judge it on the preview rather than on the number.

    Why did my PNG get bigger instead of smaller?

    PNG is lossless, and this compressor saves every image as WebP, which keeps transparency and is usually far smaller at the same look. Flat artwork already saved as a tight PNG can still come out the same size or larger; the result shows the size change, so keep the original if it did not shrink.

    What format does the compressed file use?

    WebP, whatever you drop in. Every current browser and most platforms accept it. If you need a smaller JPEG or PNG instead, use the image converter, which lets you pick the output format and quality.
