What the Image Compressor does
This tool takes a JPG, PNG or WebP picture and makes the file lighter so it loads faster, fits an upload limit, or takes up less room in an email or on a website. It is handy for bloggers trimming page weight, anyone fixing a photo that is “too large to attach,” and people who just want a leaner copy of a screenshot. The image keeps its original width and height. Only the byte size goes down.
How to use it
- Drag an image into the box, or click to pick a file from your device.
- Set the Quality value. It starts at 70% and accepts anything from 10 to 100%. A lower number means a smaller file with more compression.
- Press Compress to re-encode the picture.
- Compare the new size with the original, then download your compressed JPG.
If the result is softer than you like, bump the quality up and run it again. If it is still too heavy, drop the quality and retry. A couple of quick passes usually lands the sweet spot.
Why compress here
It is quick: the picture is processed on the spot, with no upload wait and no queue. It is private, since the work happens inside your browser and the file never leaves your computer. And it is free with no account, no watermark, and no daily cap. Because it runs locally, it even works offline after the page loads.
One thing to know: the output is always a JPG. That is the format that squeezes photos down the most, and it is why PNG or WebP inputs come back as JPG. For graphics with sharp edges or transparency you may prefer to keep PNG, so use this when smaller wins over perfect.
Tip: working through a whole folder of images? This page handles a file at a time. For batch jobs across many pictures at once, the BulkPro desktop app from the same team is built for that.
Frequently asked questions
- What image formats can I compress?
- You can drop in a JPG, PNG or WebP file. The compressor re-encodes it and gives you back a JPG, which is the format that gets you the smallest size for photos and detailed images.
- What quality setting should I pick?
- The Quality field defaults to 70%, which is a good balance for most photos. Lower it toward 40 to 50% for smaller files when some softness is fine, or raise it toward 85 to 95% when you want the image to stay crisp. Try a value, check the result, and adjust.
- Will compressing make my image blurry?
- At high quality settings the difference is hard to spot. JPG compression drops some fine detail to save space, so very low values can add visible artifacts. The tool keeps the original width and height, so only the file weight changes, not the dimensions.
- Are my images uploaded anywhere?
- No. Compression happens on your own device using your browser, so the picture is never sent to a server. You can even run it with your connection off once the page has loaded.
