Make images smaller without a visible drop in quality. Great for faster sites and email.
Big image files slow everything down. They make web pages crawl, bounce off email size limits, and eat storage you would rather keep. This tool shrinks an image's file size while keeping it looking essentially the same to the eye, so a photo that was several megabytes can drop to a fraction of that without an obvious loss in quality.
You drop in a JPG, PNG, or WebP, set how much quality you want to keep with the slider, and the tool re encodes the image at that level and gives you the smaller file to download. A lower quality number squeezes harder for a lighter file, while a higher one stays closer to the original. It is worth trying a couple of settings to find the sweet spot for your particular image.
The compression is lossy, meaning it discards fine detail your eye is least likely to notice in order to save space, which is why very high compression can eventually show soft edges or blocky patches. Photographs with lots of gradual color tolerate it beautifully. Note that a PNG, which is often used for graphics and transparency, is converted to WebP during compression, a modern format that squeezes far smaller than PNG while keeping transparency, whereas a JPG stays a JPG. That means a graphic with sharp lines or text may fare differently than a photo.
The alternative is resizing the image to smaller pixel dimensions, which is the right move when the picture is physically larger than it needs to be. Compression is what you want when the dimensions are already fine but the file is simply too heavy. The two work well together for maximum savings.
People use it to speed up a website by lightening every photo, to get an attachment under an email size cap, to fit more pictures into limited phone or cloud storage, or to prepare images for a form that rejects large uploads.
All the work happens in your browser, so the image is never uploaded, there is no account, and it costs nothing. The only real limit is your device's memory, which only matters for very large images or many at once.
PNG compresses poorly for photos, so the tool re encodes it to WebP, a modern format that gets much smaller while still supporting transparency. WebP opens in every current browser and most apps, though a very old program might not recognize it.
Around the middle is a good starting point for most photos, giving a big size cut with no obvious loss. Drop lower when size matters most, or nudge higher for images with fine detail, and compare the result before committing.
No, the width and height stay the same, only the file size shrinks. If you also want fewer pixels, use a resize tool either before or after compressing.
Each lossy pass throws away a little more detail, so repeatedly recompressing the same JPG will slowly degrade it. Compress from the original once rather than compressing an already compressed copy.
An image that is already heavily compressed has little left to remove, so the savings are small. Starting from the original high quality file gives the biggest reduction.
Yes, because PNGs are converted to WebP, which keeps transparent areas intact. A transparent graphic stays transparent after compression.
