Compress Image Online – Reduce File Size for Free
Compress Image – Reduce Image Size Free Online
Images that are too large slow down websites, clog email inboxes, and eat up storage. This image compressor reduces file size while keeping the image looking sharp. Upload your photo or graphic, compress it, and download a lighter version — all without installing anything. Works with JPG, PNG, and WebP.
How it works
Upload the image
Add a JPG, PNG, or WebP file. If the dimensions are much larger than needed, resize it first for cleaner results.
Choose compression
Pick a quality level or target size. Use lighter compression for screenshots and stronger compression for normal photos.
Download and compare
Open the compressed image and check important details before sending it to an upload form or publishing it.
Frequently asked questions
About Compress Image
Compress Image reduces file size for upload forms, profile photos, email attachments, websites, product images, and document scans. The best setting depends on the image type. A camera photo can usually be compressed heavily as JPG. A screenshot with small text may need PNG or lighter compression to stay readable. If the image dimensions are huge, resize first. A 4032-pixel phone photo does not need to stay that large for a 600-pixel profile upload. Resizing removes pixels nobody will see, then compression fine-tunes the file size. For strict targets like 100 KB, inspect the result before uploading. Faces, ID numbers, QR codes, signatures, labels, and small UI text are the details that usually fail first when compression goes too far.
