Image Compressor
Image Compressor is a free online tool that shrinks JPG, PNG, and WebP images, with automatic conversion for HEIC photos. You can fine-tune the compression quality, resize the output (with aspect-ratio lock), choose the output format, and compare the original and compressed versions side by side in real time.
Compression runs entirely in your browser — images are never uploaded to a server, and no account is needed. It is perfect for optimizing web images, meeting upload size limits for avatars and ID photos, or freeing up storage space.
How to Use
- Click to select a file or drag and drop an image
- Adjust the quality slider, and optionally set output size and format
- Click Compress and review the before/after comparison
- Download the compressed image once you are happy with the result
FAQ
Is the image compressor free?
Yes, it is completely free with no sign-up and no limits on how many images you compress.
Are my images uploaded to a server?
No. Compression happens entirely in your browser, so your images never leave your device — safe even for ID photos and other private pictures.
How much quality will I lose?
That depends on the quality setting you choose; at the default level the difference is barely visible. Use the live before/after comparison to find the best balance between file size and quality.
Which formats are supported? Can I compress in bulk?
JPG, PNG, and WebP are supported, and HEIC photos are converted automatically. Output can be JPG, PNG, or WebP. This page compresses one image at a time — use the batch image compressor on this site for multiple files.
