Compress image to 100 KB

Bring a photo or scanned document down to 100 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 100 KB in one step

    Type or pick the limit, drop the image, and the tool returns a JPG that is at or under 100 KB. It is built for the forms that enforce exact sizes: document photos for online applications, email signatures, product photos for marketplaces with strict limits, images in WhatsApp catalogues. 100 KB is a typical cap for scanned certificates, mark sheets and ID proofs on admission and visa portals.

    A phone photo of a document stays fully readable at 100 KB – text on an A4 page is clear at around 1,000 pixels on the long side. A normal photo looks fine at 800–1,000 pixels. 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 100 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 100 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 100 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 100 KB without losing quality?

    Pick the image, keep 100 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. A phone photo of a document stays fully readable at 100 KB – text on an A4 page is clear at around 1,000 pixels on the long side. A normal photo looks fine at 800–1,000 pixels.

    Can I compress a PNG to 100 KB?

    Yes. For the smallest file choose “JPG” as the output; PNG cannot be compressed by quality, so a PNG target of 100 KB is reached by shrinking the dimensions instead, which suits logos and screenshots but not photos.

    Which portals need 100 KB images?

    100 KB is a typical cap for scanned certificates, mark sheets and ID proofs on admission and visa portals.

    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 100 KB and you receive a ZIP. There is no limit and no watermark.
