Target size or quality slider

If a form gives a maximum size, type it as the target in KB. The tool lowers the quality step by step until the image fits, and keeps the result as clear as it can at that size.

If you have no strict limit, use the quality slider instead. Higher quality means a larger file. For most photos, a setting in the upper middle of the range looks almost the same as the original at a fraction of the size.

JPG or WebP output

The compressed image is saved as JPG or WebP. JPG is accepted by almost every upload form. WebP is often smaller at the same quality, but check that the form accepts it first.

JPG does not support transparency. If you compress a PNG that has transparent areas, such as a signature on a clear background, those areas become white when saved as JPG. For signatures and documents a white background is usually what forms expect.

Keep it readable

Very small targets lead to blocky or blurred images. If a photo of a document needs to stay readable, crop away the empty background first. Less area to store means better quality at the same KB.

Compression runs in your browser and your image is not uploaded to a server.

Questions, answered

How do I compress a photo to a specific KB?
Type the size in KB in the target field. The tool reduces quality until the file is at or under that size.
Why did the transparent background turn white?
JPG cannot store transparency, so clear areas are filled with white. That is expected when saving as JPG.
Does compressing change the image dimensions?
The quality slider keeps the dimensions. To change the width and height in pixels, use the resize tool.
My compressed image looks blocky. What can I do?
Raise the target or quality, or crop and resize the image first so fewer pixels share the same KB budget.
Is my image uploaded?
No. It is compressed in your browser on your own device.
