Why Use It
FAQ
How do I compress an image without losing quality?
Use a quality setting of around 70-85% when compressing to JPEG or WebP. This removes data that's imperceptible to the human eye while keeping the image visually identical, drastically reducing file size.
What is the best format to compress photos?
JPEG and WebP are best for photos because they use lossy compression tuned for photographic detail. PNG is better for screenshots, logos, and graphics with flat colors or transparency, but produces larger files for photos.
Is it safe to compress images online?
It's safe when compression happens locally in your browser, as it does here. No file is uploaded to a server, so there's no risk of your image being stored or exposed.
Does compressing an image reduce its resolution?
No. Compression reduces file size by optimizing how pixel data is encoded, not by changing the image's width or height. To change dimensions, use the resize tool instead.

Smaller images, faster websites, no quality you can actually see lost
Large, uncompressed images are one of the most common causes of slow-loading websites. Every extra kilobyte in a hero image or product photo adds to page load time, which affects both user experience and search engine rankings through Core Web Vitals metrics like Largest Contentful Paint. Compressing images before you upload them is one of the simplest, highest-impact optimizations you can make to a website or app.
This compressor uses your browser's built-in Canvas encoder to re-encode images at an adjustable quality level. For photographic images, converting to JPEG or WebP at 70-85% quality typically cuts file size by 50-80% with no visible difference from the original. PNG stays lossless, so it's best reserved for screenshots, logos, and graphics that need sharp edges or transparency.
Because everything runs client-side, there's no upload wait and no limit on how many images you compress. It's a practical way to shrink photos for email attachments, product listings, blog posts, or anywhere file size matters.
