How to Compress an Image Without Ruining It
Large photos slow pages down, but heavy compression can blur them. Here is how to find the balance.
What is the Image Compressor?
Upload a photo and pick a quality level and a maximum width. The tool resizes oversized images and re-encodes them at your chosen quality, all on your device. No file is uploaded to a server. Very low quality settings will visibly soften fine detail, so preview before you keep the result.
How to use it
- Upload an image
- Set quality and max width
- Download the compressed image
Worked example
With quality 80 and a 1920 px cap, a large photo is resized if needed and re-encoded as a smaller JPEG you can download.
How much quality should I use for web images?
Quality around 75 to 85 usually keeps photos looking sharp on screen while cutting file size sharply, and resizing to the display width saves even more.
Frequently asked questions
Does compression reduce quality?
Yes, at lower quality settings some fine detail is lost, which is the trade-off for a smaller file.
Is my image uploaded anywhere?
No, compression runs in your browser, so the file stays on your device.
