Image Compressor
Reduce an image’s file size by changing its quality, dimensions or output format. The result panel shows the real before-and-after size, so you can balance visual quality with a smaller download.

How to compress an image
- 1
Select a JPEG, PNG or WebP image supported by your browser.
- 2
Choose an output format. JPEG or WebP is usually smaller for photographs; PNG is useful when transparency or crisp flat graphics matter.
- 3
Adjust the quality control for a lossy format. Lower quality normally reduces size but can introduce visible artifacts.
- 4
Optionally reduce width and height. Keeping the aspect ratio prevents stretching.
- 5
Compress, compare the preview and byte size, then download only when the result looks acceptable.
How browser image compression works
Your browser decodes the selected image and draws it to a Canvas at the requested dimensions. It then encodes a new JPEG, PNG or browser-supported WebP file. Quality settings affect lossy formats; PNG uses lossless compression, so photographic PNG files may remain large.
Reducing pixel dimensions can have a larger effect than moving the quality slider a small amount. A 4000-pixel-wide camera photo often contains more detail than a web page needs. Resizing it to the actual display width can remove unnecessary pixels before encoding.
Can I compress an image to 20KB, 100KB or 200KB?
You can work toward a target by adjusting dimensions, quality and format, but an exact file size is not guaranteed. A detailed photo, a simple logo and a transparent graphic compress very differently. Use the actual output size shown by the tool and make small adjustments until the result fits your requirement.
Example compression workflow
For a 2 MB product photo, try WebP or JPEG at about 80% quality and reduce the width to the largest size your page will display. Compare fine text, product edges and gradients in the preview. If artifacts are visible, raise quality slightly; if the file remains too large, reduce dimensions.
Important quality notes
- Compression results depend on the original image, dimensions, visual detail and browser encoder.
- JPEG does not support transparency. A transparent source needs a background colour when exported as JPEG.
- Repeatedly recompressing an already lossy image can reduce quality further.
- Large images use browser memory while decoding and resizing.
- Always inspect logos, screenshots, small text and fine edges before using the output.

Image Compressor FAQ
How can I reduce an image to 200KB?
Reduce dimensions if they are larger than needed, choose JPEG or WebP for a photograph, lower quality gradually and check the actual output size after each change.
Does image compression reduce quality?
Lossy JPEG and WebP compression can remove detail. A moderate setting may look unchanged at normal size, but you should inspect important areas before downloading.
Should I resize the image as well as compress it?
Resize when the original pixel dimensions are larger than the final use. Fewer pixels often produce a much smaller file with little visible loss at the intended display size.
Which image format is smallest?
It depends on the image and browser. WebP or JPEG often works well for photos. PNG may be better for transparency, line art or screenshots but can be larger.
Are images uploaded to Shopshubb?
No. This ToolHub compressor processes the image locally in your browser and does not upload it to the ToolHub server.
Why is my PNG still large?
PNG is lossless and photographic images contain many colours and details. Reducing dimensions or switching to a lossy format may produce a much smaller result.
