Short answer: We.Inc's free Image Compressor shrinks JPG, PNG, and WebP images by choosing an output format, a quality level, and an optional maximum width, then shows the before and after size for every file. Everything runs in your browser, so photos are never uploaded.

Make images smaller without making them look worse. Choose an output format, a quality and an optional maximum width, and see the before and after size for every file. Everything runs in your browser, so your photos are never uploaded.
File size comes from two things: how many pixels the image has and how much detail is stored per pixel. A 12 megapixel phone photo has four times the pixels of a 2000 pixel wide web image, so resizing alone can cut the size by 75 percent before any compression happens.
Compression then decides how much fine detail to keep. Lossy formats (JPG, WebP) throw away detail the eye is unlikely to notice; lossless formats (PNG) keep every pixel exactly and rely on repeating patterns, which is why they work well for flat logos and badly for photos.
Use WebP for almost everything on a website: photos, illustrations and transparent graphics. Use JPG when the file will be emailed or opened in older software. Use PNG for screenshots with lots of text, or when you need an exact, lossless copy.
If you only need format conversion with batch download, the WebP converter does the same job with fewer options.
Slow pages lose visitors, especially on phones. Heavy images also use up storage on your host and data on your customers' plans. Compressing before you upload is a five minute habit that keeps every page quick, and it is one of the first things the free website checker looks at.
Yes. It is free with no signup and no limits we impose. Images are processed by your own browser, so they never leave your device.
JPG and WebP compression is lossy, so some detail is discarded. At quality 75 to 85 the difference is very hard to see for photos. The preview lets you check before you download.
PNG is lossless, so the quality slider does not apply. To shrink a PNG, reduce its width or switch the output to WebP, which keeps transparency and is usually far smaller.
Yes. Re-drawing an image through the browser canvas drops EXIF data such as camera details and GPS location. That is good for privacy, but it also means the date taken is not kept.
There is no fixed limit, but very large images (above about 50 megapixels) can run out of memory on phones. On a laptop, normal camera photos work fine.
