Compress Image reduces the file size of your photos so websites load faster and emails send easily. Pick a quality level and an output format, then download the smaller images. Everything is done in your browser.
Why compress images?
Pictures are usually the heaviest part of any web page, email or document. A single phone photo can be four to eight megabytes. Compressing images makes pages load faster, saves storage and mobile data, helps you meet upload limits and improves how your website performs in search results. This tool reduces the file size of JPG, PNG and WebP images right in your browser, and shows how much space you saved.
Where image compression helps
- Websites and blogs. Smaller images make pages faster, which visitors and search engines both like.
- Email and messaging. Attachments stay under the size limit.
- Forms and applications. Many portals restrict photo uploads to 100 or 200 kilobytes.
- Online shops. Product photos load quickly, even on slow mobile networks.
- Storage. Thousands of photos take less space on your phone or in the cloud.
Lossy compression in simple words
Most photo compression is lossy: it removes tiny details the human eye barely notices. A quality value of 100 keeps almost everything but gives a big file. Values between 60 and 80 usually reduce the size dramatically with differences that are hard to see. Below 50, blocky patches and blurry edges may appear. The tool lets you pick the number, so you can balance size and quality for your own purpose.
JPG or WebP output?
JPG is understood everywhere and works for any photograph. WebP is a modern format that often produces files 25 to 35 percent smaller than JPG at similar quality, and all current browsers support it. If your image is for a website, WebP is a good choice. If you need to open the file in older software, choose JPG.
How it works
Each image is drawn onto a canvas in your browser and then saved again with the quality and format you selected. Transparent areas are filled with white when saving as JPG, because JPG has no transparency. Several images can be processed at once and the tool shows the total size before and after.
Privacy
Your photos are never uploaded. They are processed on your device, so personal pictures and ID photos stay private.
Tips for the best balance
- Resize first. A photo that is 4000 pixels wide is rarely needed on a website. Reducing dimensions with the Resize Image tool saves far more than quality changes alone.
- Start with quality 70 and compare. Lower it only if the file is still too big.
- Do not compress the same image repeatedly. Each round loses a little more quality. Always compress from the original.
- Keep the original files as a backup.
Troubleshooting
The result is not much smaller. The photo may already be compressed. Try a lower quality or reduce the dimensions.
My PNG logo looks different. Output is JPG or WebP, which are better for photos. For logos with sharp edges or transparency, use the Convert Image tool and keep PNG.
WebP does not work. Very old browsers cannot create WebP. Choose JPG.
Free and unlimited
Select your images, choose the quality and download the compressed files. No sign-up, no watermark and no limit.
A real-world example
Ayesha runs a small online shop and uploads product photos straight from her phone. Each picture is about 5 megabytes, so her product pages load slowly. She selects twenty photos, sets quality to 75 and chooses WebP. The total size drops from about 100 megabytes to around 8, and her pages feel much faster for customers on mobile data.
Checklist before you download
- You resized very large photos first, if needed.
- You compared one compressed image with the original.
- You chose JPG if the receiving software may not support WebP.
- You kept the original photos in a safe place.

More questions about this tool
Will compression remove EXIF data such as location?
Images are redrawn and saved as new files, so camera details and location information are not carried over. This is a nice privacy bonus when you publish photos online.
Can I compress screenshots?
Yes. Screenshots with text may look softer at low quality, so try 80 or higher and compare the result with the original.
How to use Compress Image
