Compress Images Online for Free

How to compress images

1. Add your images. Drag JPG, PNG or WebP files onto the box above, or click it to choose them. You can add many at once.
2. Choose your settings. Quality 75 and WebP suit most uses. Lower the longest side if the image only needs to fit a web page or an email.
3. Click Compress, then Download. Each image shows its old and new size, so you can see exactly how much you saved.

Why compress images?

Large images slow everything down. A single photo from a modern phone is often 3–8 MB, which is too big for many upload forms and email attachment limits, and makes web pages load slowly. Compressing removes detail your eyes can't see and, if you like, scales the image to a sensible size. A multi-megabyte photo typically becomes a few hundred kilobytes and looks the same on screen.

For websites the benefit is bigger still. Smaller images mean faster pages, which visitors notice and search engines reward, because loading speed is part of how Google measures page experience. Smaller files also take up less room in cloud storage and on your phone, and they back up faster.

Who compresses images?

• Bloggers and website owners speed up pages and stay within upload limits.
• Online sellers prepare product photos that load fast on every marketplace.
• Students fit images into assignment portals with strict size caps.
• Professionals keep emails, slides and documents small enough to send.
• Everyone shares holiday photos without “file too large” errors.

How it differs from typical image compressors

Many online compressors upload your images to their servers to process them. Free plans usually cap how many images you can do at once or how big each one can be, and some add watermarks or ask you to create an account first. Uploading also takes time, especially for a batch of large photos on a slow connection.

This compressor runs in your browser, so there's nothing to upload and no queue. There is no limit on how many images you compress, files can be up to 50 MB each, and you can convert to WebP and resize in the same step. Every image shows its size before and after, so you know exactly what you saved, and you can stop a long batch at any time.

Choosing the right settings

• For websites: WebP, quality 75, longest side 1600–2000 px. That covers full-width images on almost every screen.
• For email and messaging: JPG, quality 70, longest side about 1280 px. Small enough to send, sharp enough to view on any phone.
• For printing: keep the original size and use quality 90 or higher. Print needs far more pixels than a screen.
• For screenshots and graphics with text: “Same as input” keeps a PNG lossless, so edges and lettering stay crisp, though it won't shrink as much as WebP.

Your images stay private

Every image is compressed by your own browser and never sent to a server, so nobody else can see it, store it or use it. The tool also strips hidden metadata such as the GPS coordinates your phone records, which protects your location when you post photos online. The page runs under a strict security policy that prevents it from sending files anywhere, which makes it suitable for personal photos, ID scans and confidential screenshots. Because nothing is uploaded, it also works well on slow or metered connections.
