Compress an image to a target size
Upload an image and select JPG, PNG or WebP output. In quality mode, choose the encoder quality and maximum edge. In target mode, enter a size such as 100 KB or 200 KB. The tool tries to fit under that limit by adjusting quality and, when allowed, reducing dimensions.
Read the result before downloading
The result shows actual dimensions, encoded format, file size, and the percentage change from your original file. Some source images are already efficient and can become larger after conversion. A message reports when a requested size cannot be reached; the tool does not label an oversized file as meeting your target.
PNG and image detail
PNG does not support a lossy quality setting through this tool. Choose WebP or JPG for quality-based compression, or allow PNG dimensions to shrink. Very small targets can remove detail that matters in jewellery, fabric patterns or text. Always inspect the output at the size where customers will see it.
Quick answers
How can I compress an image to 100 KB or 200 KB?
Choose target-size mode and enter 100 or 200 in the KB field. Select JPG or WebP for quality-based compression. Allow further resizing if needed, then check whether the result met the target.
Can I reduce image size without changing dimensions?
Set the maximum edge to at least the original longest edge and turn off further resizing. For JPG and WebP, the compressor can lower quality while retaining dimensions. A small target may remain unreachable.
Why is the compressed image larger than the original?
The original may already be efficiently encoded, or your selected format and quality may need more bytes. The tool reports the actual increase instead of describing every result as a reduction.
