Compress image

Smaller files, same format. PNGs stay pixel-perfect. Compressed on your device.

Smaller, same lookBefore and after sizes show here.

    How to use it

    1. Drop your images into the box, or tap it to choose them.
    2. Drag the line across the picture to compare before and after, and use Actual pixels to check the detail.
    3. Move the quality slider, or set a max file size. One image updates as you go; for several, click Compress. Then download.

    Questions

    Will my images lose quality?

    JPG, WebP and AVIF are re-saved at the quality you pick; at 70–80 most people can't see a difference. PNGs are compressed losslessly, so every pixel stays exactly the same.

    Can the file get bigger?

    JPG, PNG, WebP and AVIF files never do: if compressing would not make one smaller, you get the original back unchanged. HEIC photos have to become JPGs, which can be larger at high quality.

    How does max file size work?

    If the image is over your limit at the chosen quality, quality is lowered until it fits. The size in pixels never changes, so a very low limit can fail: resize the image first. PNGs stay lossless, so they can't be pushed to a limit, and the quality slider doesn't change them.

    What happens to HEIC photos?

    They come out as JPGs, because most apps can't open HEIC.

    Does the result keep my photo's date and location?

    No. Saved images keep the picture and its colour profile, without date, GPS location or camera details.

    Are my images uploaded?

    No. Everything runs inside your browser on your own device. Your files are never sent to a server, and you can check: open your browser's developer tools, watch the Network tab, and you will see no upload.

    Is it free? Are there limits?

    Free, with no sign-up, no watermark and no daily limit. Because the work happens on your device, it costs us nothing to run, so there is nothing to ration. You can add up to 50 images at a time.
