Compress JPG, PNG and WebP images to reduce file size without visible quality loss.
What is the Image Compressor?
Large images are the most common reason websites load slowly and forms reject uploads. This image compressor reduces the file size of JPG, PNG and WebP images – often by 60–90% – while keeping them looking sharp. Adjust the quality and maximum width and watch the new file size update live.
Compression happens entirely in your browser, so private photos and documents never leave your device.
How to use the Image Compressor
- Choose an image.
- Move the quality slider (70–80% is a good balance) and set a maximum width.
- Download the compressed image when the size looks right.
Why compress images?
- Faster websites – smaller images improve Core Web Vitals and Google rankings.
- Upload limits – many job, university and government portals accept only files under 100–500 KB.
- Less data – quicker sharing on WhatsApp and email.
JPG vs WebP vs PNG
JPG is best for photos and works everywhere. WebP is usually 25–35% smaller than JPG at the same quality and is supported by all modern browsers and WordPress. PNG is lossless and best for logos, screenshots and graphics with transparency.
Frequently asked questions
Will people notice the quality loss?
At 70–85% quality the difference is usually invisible on screens.
Why is my compressed PNG bigger?

How do I compress to under 50 KB?
Lower the max width to around 800 px and quality to 50–60%.
Is there a file size limit?
No hard limit, but very large images may be slow on older phones.
This image compressor is 100% free, needs no signup and works on phones, tablets and computers. Your data is processed in your browser and never uploaded.
