How to use the Compress Image tool
- Choose the image you want to make smaller.
- Move the quality slider, or type a target size in KB.
- Pick JPG for photos or WebP for the smallest web files.
- Press Compress, compare the size and download.
How compression works
Photo formats like JPG and WebP can drop fine detail that the human eye barely notices. At a quality around 70 to 80 percent, most photos look the same as the original but take up a fraction of the space, often 60 to 80 percent smaller.
Faster websites, better SEO
Page speed affects how visitors feel about a site and is part of how search engines judge it. Images are usually the heaviest part of a page, so compressing them is one of the quickest wins for any blog, portfolio or online store.
Hit an exact size
Government portals, job applications and exam forms often demand files under a set size. Enter that number in the target box and the tool searches for the highest quality that still fits. If quality alone is not enough it gently lowers the dimensions as well.
A note about PNG
PNG files are lossless, which is great for logos and screenshots but means they cannot be compressed by a quality setting. This tool converts them to JPG or WebP to cut the size. If you need transparency, choose WebP, which keeps it.
How to reduce the file size of a JPEG
Open the photo, start with quality at 75 percent and press Compress. Compare the result: if it looks the same as the original, try 65 percent for an even smaller file. If you can see blocky areas in skies or smooth skin, go back up. When a form gives you a hard limit, simply type that limit in the target box and the tool finds the best quality that fits.
Compress pic files for sharing
Messaging apps and email providers often recompress or reject large attachments. Compressing a pic before you send it means you decide the quality, not the app. A typical 4 MB phone photo can usually become 300 to 600 KB and still look great on any screen.
Frequently asked questions
How much can I reduce file size?
Typical phone photos shrink by 60 to 90 percent depending on the quality you choose.
What is the best quality setting?
70 to 80 percent is a good balance for most photos on the web.
Should I use JPG or WebP?
WebP is usually 25 to 35 percent smaller at the same quality and works in all modern browsers. Use JPG when you need maximum compatibility.
Is compression done on a server?
No. It happens entirely in your browser, so your files stay private.
How do I compress a picture to a specific size?
Type the size in the "target size" box, for example 200, and press Compress. See also our presets for 200 KB, 500 KB and 1 MB.
