Large photos slow down websites, bounce from email attachments, and eat storage. An online image compressor reduces file size while keeping the image looking sharp — ideal before you email a photo, upload it to a site, or add it to a document.
Why file size matters
- Email — many providers reject or refuse to send attachments above 25MB; most images should stay far smaller.
- Web performance — a lighter image loads faster and improves your page speed score.
- Storage — compressing a 5MB photo to 200KB saves space across your library.
How to compress an image online
Drag and drop your image into the compressor, or click to browse your files. Use the quality slider to tune the trade-off between size and sharpness, pick an output format (JPEG, WebP or PNG), and watch the live preview update the estimated size. When you are happy, hit Download. Your original file is never modified — you always receive a new compressed copy.
JPEG, WebP or PNG?
JPEG is the default choice for photos. WebP usually delivers even smaller sizes at equal quality and works in every modern browser. PNG is lossless, so it suits screenshots and graphics with text, but produces bigger files. Use the preview to compare the same image in each format and pick the best fit.
Compress without uploading
Because compression happens locally in your browser, your photos never leave your device. That makes this tool safe for headshots, documents with personal details, or any image you would rather not send to a third-party server.
