Compress image to 500 KB

Bring a photo or scanned document down to 500 KB or less for a form that refuses bigger files. The size is checked before you download, and the image never leaves your device.

    Compress a photo to 500 KB in one step

    Type or pick the limit, drop the image, and the tool returns a JPG that is at or under 500 KB. It is built for the forms that enforce exact sizes: photos for blogs and online shops, multi-page document scans, images in presentations, community and social uploads. 500 KB is a common upload limit for university portals, job sites and property listings.

    500 KB holds a full-quality 1,600–2,000 pixel photo. For documents it is more than enough for crisp text and stamps. The result size is shown before you download, so there is no guessing and no re-uploading to find out whether the portal accepts it.

    How to reduce an image to 500 KB

    1. Add the image. Click the sheet or drag the photo onto it. JPG, PNG, WebP, HEIC (iPhone), GIF, BMP and AVIF all work, and you can add several at once.
    2. Keep 500 KB as the target. It is pre-filled. Change it if the form says a different number – the presets cover 20 KB to 1 MB.
    3. Choose the output format. JPG gives the smallest file for photos and scans. Use PNG only when the portal insists on it or the image is a logo with flat colours.
    4. Press Compress. The tool tries quality levels first, then resolution, until the file fits. The new size and dimensions appear on the thumbnail.
    5. Download. One image downloads directly; several come as a ZIP. Nothing is stored anywhere.

    What happens to the picture

    Every JPEG has a quality setting from 1 to 100. Phone cameras save at 90–97, which is far more than a form needs. Dropping to 75–85 removes about half the file with no change you can see at normal size. If that is not enough for 500 KB, the tool reduces the pixel dimensions in small steps and checks the size after each one, stopping as soon as it fits. It never goes below 32 pixels and tells you if the limit was impossible for that image.

    Need the image at an exact pixel size too (for example 200 × 230 px for a photo, or 140 × 60 px for a signature)? Use the image resizer or the passport photo maker, which can resize and cap the KB in one go.

    Frequently asked questions

    How do I compress an image to 500 KB without losing quality?

    Pick the image, keep 500 KB as the target and press Compress. The tool lowers JPEG quality first, which is invisible at the top of the range, and only reduces resolution if quality alone is not enough. 500 KB holds a full-quality 1,600–2,000 pixel photo. For documents it is more than enough for crisp text and stamps.

    Can I compress a PNG to 500 KB?

    Yes. For the smallest file choose “JPG” as the output; PNG cannot be compressed by quality, so a PNG target of 500 KB is reached by shrinking the dimensions instead, which suits logos and screenshots but not photos.

    Which portals need 500 KB images?

    500 KB is a common upload limit for university portals, job sites and property listings.

    Is the photo uploaded to your server?

    No. Compression runs in your browser with JavaScript. The image never leaves your device, which also makes it quick on slow connections.

    Can I do several photos at once?

    Yes. Add as many as you like; each one is compressed to 500 KB and you receive a ZIP. There is no limit and no watermark.
