Image Compressor
Image Compressor reduces the file size of a JPG, PNG or WebP by re-encoding it at a quality you choose, with a live before-and-after comparison. Because the image is redrawn to produce the smaller file, EXIF metadata — including GPS coordinates and camera details — is removed along the way.
Runs entirely in your browser — nothing you enter is uploaded.
ImageLocation data is removed. Photos carry hidden EXIF metadata — GPS coordinates, camera model, timestamp. Compressing here redraws the image, so the output has none of it.
About compressing images
Compression here is lossy for JPG and WebP: the quality slider decides how much detail the encoder may discard, and the size falls steeply at first for changes almost nobody can see. Around 70–80% is usually indistinguishable from the original at normal viewing size while cutting the file by more than half. PNG is lossless by design and ignores the quality setting entirely, which is why the slider disappears when you select it — for a photograph, switching to JPG or WebP is what actually reduces the size.
The privacy side effect is worth knowing about. Compressing redraws the image from its pixels, so everything that was not pixels is left behind: the GPS coordinates your phone recorded, the camera model, the serial number, the timestamp. Photographs posted online routinely carry all of it. Running an image through here before sharing removes it, and because the work happens in your browser, the original never leaves the device either.
Common questions
- What quality setting should I use?
- For photographs, 70–80% is the usual sweet spot: the file is often less than half the size and the difference is invisible at normal viewing size. Go lower for thumbnails, and higher when the image will be enlarged or printed. The comparison updates as you change it, so the honest answer is to lower it until you can see the difference, then go back a step.
- Why is there no quality slider for PNG?
- Because PNG compression is lossless — it reproduces every pixel exactly, so there is no quality to trade away and the setting would do nothing. That is the right choice for screenshots, logos and anything with sharp edges or transparency. For a photograph, PNG produces a very large file, and converting to JPG or WebP is what actually reduces the size.
- Does compressing remove EXIF and GPS data?
- Yes. The image is decoded to pixels and re-encoded, so metadata attached to the original file is not carried into the new one. That includes GPS coordinates, camera make and model, lens details and timestamps. If your goal is specifically to strip location data before sharing a photo, compressing it here at high quality does that.
- Will compressing an already-compressed image shrink it further?
- A little, but at a cost. Re-encoding a JPEG discards detail again, and repeated cycles accumulate visible damage even at high quality settings, because each pass compresses the artefacts of the last. Compress from the original wherever you can, and keep that original rather than overwriting it.
