Image compressor online

How to compress an image

1. Choose a JPG, PNG, or WebP image from your device.
2. Start with the default quality and max-width settings.
3. Compress the image and check the downloaded file size.
4. If the result is still too large, reduce max width or lower quality gradually.
5. Open the downloaded image once to confirm it is clear enough for your use.

For forms and portals, compare the final file with the official size, dimension, format, and readability rules before submitting.

When to use the image compressor

Use this general compressor when you need a smaller image for email, a website, a profile upload, a document portal, or a form that gives a file-size limit but not a specific target page. It is a flexible starting point when you want to control both quality and maximum width.

Quality and readability tradeoffs

Lower quality usually reduces file size, but it can soften faces, document text, signatures, and small details. Reducing width first often gives a cleaner result for very large phone photos because the image has fewer pixels to store before quality is lowered.

For text-heavy screenshots or forms, check readability after compression. If the upload portal allows a larger file, use the least aggressive settings that meet the rule.

Troubleshooting compression results

• If the file is still too large, reduce max width before dropping quality too far.
• If the image looks blurry, try a higher quality setting or a larger size limit.
• If the portal asks for an exact limit, use a target page such as compress image to 50KB or compress image under 100KB.
• If dimensions matter, resize first with the image resizer.
