Compress Image

In my experience, you can expect a 40 to 70 percent file size reduction at the high quality setting, and 70 to 90 percent at medium quality. I regularly compress 4MB smartphone photos down to under 800KB with no visible difference. The exact savings depend on the image content, since photos with lots of detail and color gradients compress differently than screenshots or graphics with solid colors. PNGs with large flat areas often see the most dramatic drops. A 2MB PNG screenshot might come down to 200KB as a compressed JPG. For comparison, TinyPNG typically achieves similar ratios but requires uploading to their servers. Here you get the same results without your images ever leaving the browser, which is a really nice bonus when you are working with client photos or sensitive personal pictures.

Yes, and honestly this is a feature, not a bug. When you compress an image here, all EXIF metadata gets stripped automatically. That includes your camera model, lens settings, the exact GPS coordinates where the photo was taken, and the timestamp. For privacy-conscious people, this is huge. I have seen folks accidentally share location data embedded in vacation photos without realizing it. The compression process uses the browser's Canvas API to re-encode the image, and Canvas output simply does not carry EXIF data forward. If you specifically need to preserve metadata for archival or photography purposes, you would want a different workflow. But for web uploads, social media, email attachments, and sharing with others, stripping EXIF is the safer default. Tools like ImageOptim offer a separate toggle for this, but here it happens automatically as part of the compression.

No account, no email, no sign-up, nothing. You open the page, drop your image, adjust the quality slider, and download the compressed file. That is the entire workflow. I find this matters more than people think, because most competing tools gate you behind friction at some point. TinyPNG gives you 500 free compressions per month but requires an API key for automation. Squoosh is also free and excellent, but it is a Google project with an uncertain long-term future. Canva needs a full account. Here on JustUse.me there is zero friction and no daily limits. The tool runs entirely in your browser using the Canvas API, so there is no server cost per image, which is why there is no reason to require registration. You can compress as many images as you want, as often as you want.

Yes, and I would say this is the single most common use case. Set the quality slider to 80 or 85 percent for web images and you will get a dramatic file size drop with no perceptible difference to your visitors. I have tested compressed versus original images on real websites and nobody can tell the difference at 85 percent quality. The target for web performance is under 200KB per image, and most smartphone photos compress from 3 to 5MB down to 150 to 300KB at that setting. Google PageSpeed Insights specifically flags uncompressed images as a performance issue, so this tool fixes that in seconds. For comparison, Squoosh gives you more granular control over encoding options, but for a quick compress-and-download workflow with no learning curve, this gets the job done faster. One tip: always compress after resizing, not before, since resizing already reduces file size on its own.
