How to compress an image online
- Drag your JPG, PNG or WebP files into the box above, or click it to browse your device. You can add several images at once.
- Set the quality slider — 80 is a great starting point for photos.
- Optionally change the output format. Converting a PNG screenshot to WebP often cuts its size by 90% or more.
- Watch the size drop next to each file, then hit Download — or Download all for the whole batch.

Why compress your images?
Large images are the number-one cause of slow web pages, bloated emails and rejected form uploads. A photo straight off a phone can easily weigh 5–10 MB, while the version you actually need — for a website, a listing, a job application or a support ticket — usually looks identical at a tenth of the size. Compressing images speeds up page loads, improves Core Web Vitals and SEO rankings, saves storage and bandwidth, and gets you under those pesky “maximum file size” limits.
Unlike most online compressors, MyMintCut does the work on your device using your browser’s built-in image engine. Nothing is uploaded, so it’s just as safe for a passport scan as it is for a meme — and there are no queues, accounts or watermarks.
Frequently asked questions
Are my images uploaded to a server?
No. The compressor runs entirely in your browser using the HTML5 Canvas API. Your images never leave your device, and closing the tab removes every trace of them.
Which image formats are supported?
You can compress JPG, PNG and WebP files up to 50 MB each. You can also switch the output format — for example, compress a PNG into a much smaller WebP or JPG.
What quality setting should I use?
For photos, a quality of 70–85 usually cuts the file size dramatically with no visible difference. Go lower for thumbnails and previews, higher (90+) for images with fine text or sharp edges.
Why doesn't the quality slider change my PNG file?
PNG is a lossless format, so it has no quality setting. To make a PNG significantly smaller, switch the output format to WebP or JPG using the format selector.
