What Is an Image Compressor?
An image compressor reduces the file size of a picture so it loads faster and takes less space. Smaller images help web pages load quickly, make emails and uploads easier, and save storage on your phone or computer. This free image compressor re-saves your pictures at a quality level you choose and shows exactly how much smaller each one became.
How to Compress an Image
- Choose one or more images. You can select up to 20 JPG, PNG or WebP files at once.
- Set the quality. Around 70 to 80 percent is a good balance for photos. Lower numbers make smaller files but may show blur or blocky areas.
- Optionally set a maximum width, then press Compress images and download the results.
Choosing the Right Settings
Quality
Quality applies to JPEG and WebP. Try 75 first, check the result, and lower it only if you need a smaller file.
Output format
Keep original format leaves JPG as JPG, PNG as PNG and WebP as WebP. WebP often gives smaller files than JPEG at similar quality, and modern browsers support it. If you pick JPEG for a PNG with transparency, the transparent areas become white.
Maximum width
Photos from phones and cameras are often much wider than a web page needs. Setting a maximum width such as 1600 pixels can shrink the file far more than quality alone. Images smaller than the width you set are not enlarged.
Why Browser Based Compression?
The compression happens on your own device. Your pictures are not uploaded to our servers, which is good for private photos and saves time on slow connections.
Limits to Know About
- PNG files are lossless, so quality settings do not shrink them. To reduce a PNG, set a maximum width or choose WebP or JPEG as the output format.
- If the result is not smaller than the original, the tool keeps the original file and tells you so.
- Re-saving removes metadata such as camera details and location data.
- Compression is lossy for JPEG and WebP. Keep your original files if you may need full quality later.
- Animated GIFs and other formats are not supported.
Tips for Smaller Images Without Losing Clarity
Resize first, then compress. Choose the format that fits the image: photos suit JPEG or WebP, while logos and screenshots with flat colors suit PNG. Compare the result with the original at the size it will be shown. If you also need descriptive text for accessibility and search, try the alt text generator.
Frequently Asked Questions
Is this image compressor free?
Yes. It is free and needs no sign-up.
Are my images uploaded?
No. They are processed in your browser and are not sent to our servers.
How much smaller will my image be?
It depends on the picture and settings. Photos usually shrink the most. The tool shows the before and after size for every file.
Why did my PNG not get smaller?
PNG compression is lossless. Set a maximum width or choose WebP or JPEG to reduce the size.
Does compression reduce image quality?
JPEG and WebP compression is lossy, so very low quality settings can show blur. Around 75 percent usually looks fine for the web.
