How to compress image to 100 KB

  1. 1

    Add your image

    Drop a JPG, PNG or WebP. You can add several images and compress them with the same settings.

  2. 2

    Set JPG, quality and maximum width

    Choose JPG as the output format, then start with quality 75% and a maximum width of 1,200 px. Photos from a phone usually come out between 60 and 100 KB.

    Tip: Pixel size matters more than quality. Halving the width roughly quarters the file size.

  3. 3

    Check the size, then download

    The result shows the old and new dimensions and file size. If it is still over 100 KB, lower the quality or the width a little and run it again.

Tips for a better result

Profile pictures
Profile photos are shown small. 600 px wide is plenty, and leaves room to keep the quality high.
PNG will not get there
PNG is lossless, so the quality slider does nothing for it. Switch the output to JPG to reach 100 KB.
Crop before you compress
Cutting away background around a face, signature or document leaves fewer pixels to store, so the file can stay sharper at the same size.
Location data is removed
The image is redrawn from its pixels, so camera and GPS details are not carried into the new file.

Questions about Compress Image to 100 KB

Can Docmint guarantee an image under 100 KB?

It shows you the exact new size before you download, so you always know. There is no automatic target yet: you adjust quality and width until the size fits, which usually takes one or two tries.

Should I use JPG or WebP?

Use JPG when a form asks for it, which most do. WebP is smaller at the same quality and fine for websites, but some upload forms reject it.

Will the image look worse?

Some detail is lost at small sizes; that is the trade-off. Faces and printed text stay readable at the settings suggested here. Zoom into the preview before you upload it anywhere official.

Is my file uploaded?

No. Docmint reads and processes the file inside your browser. It is never sent to a server, so there is nothing for anyone to store, scan or lose.
