How to use the Image Compressor
- 1
Add your images
Drop JPG, PNG or WEBP files onto the box above, browse, or paste with Ctrl+V.
- 2
Choose quality and format
Lower quality means smaller files. “Best” keeps JPGs as JPG and turns PNGs into WEBP for the biggest savings.

Download the smaller files
See exactly how much space you saved, then download each file or all of them as a ZIP.
Why compress images?
Large images are the number one reason websites load slowly. Compressed images load faster, rank better on Google, use less mobile data and are easier to email or upload to forms with size limits.
JPG (also called JPEG) is the most widely used photo format. It uses lossy compression to keep files small and works everywhere, but it does not support transparency and loses a little quality every time it is re-saved.
PNG is a lossless format that keeps every pixel exactly and supports transparent backgrounds. It is ideal for logos, icons, screenshots and graphics, but photos saved as PNG are often very large.
WebP is a modern image format created by Google. It supports both lossy and lossless compression plus transparency, and typically produces files 25–35% smaller than JPG at the same visual quality. All modern browsers support it.

Frequently asked questions
How much can I reduce my image size?
Most photos shrink by 50–80% at the default setting with no visible difference. PNG files converted to WEBP often shrink even more.
What if an image is already optimized?
If compressing would make a file bigger, the tool keeps your original instead, so you never end up with a larger file.
Is this image compressor tool free?
Yes. It is completely free with no sign-up, no watermarks and no limits on the number of images.
Are my images uploaded to a server?
No. Your images are processed entirely inside your browser, so they never leave your device. That makes it private and very fast, even for large files.
Can I compress many images at once?
Yes. Drop or select as many images as you like. Each one is processed in turn, and you can download them one by one or all together as a ZIP file.
Does it work on iPhone, Android and Mac?
Yes. It runs in any modern browser on phones, tablets and computers. Nothing needs to be installed.
