Online Image Compressor
ResizeHero’s image compressor reduces the file size of supported images using processing performed in your browser. You can select an output format and adjust the quality before downloading the result.
Why compress images?
Smaller image files can use less storage and require less data to transfer. Image compression can be useful when preparing photos for websites, email, documents, and social media.
How does the image compressor work?
Select an image, choose the output format, adjust the quality when applicable, and select Compress Image. The browser creates the resulting image locally and provides it for download.
Does compression always reduce file size?
No. The resulting size depends on the original image, dimensions, format, and quality setting. An already optimized image may produce a similar or larger file after conversion.
JPG, PNG, and WebP compression
JPEG and WebP output can use the quality setting. PNG output uses lossless PNG encoding and does not respond to the quality slider in the same way.
Image privacy
