Image Compressor
Make photos smaller without uploading them anywhere
Settings
70–80 is a good balance for photos. Lower means a smaller file and more visible artefacts.

About the Image Compressor
Large photos slow pages down, bounce off email attachment limits and fill up upload forms. This tool re-encodes your images as JPEG or WebP at the quality you choose and can shrink their dimensions at the same time. Everything happens on your device — the files are never uploaded, which makes it safe for documents, IDs and private photos.
Which quality should I use?
For photos, 70–80 usually cuts the file size by more than half with no difference you would notice on screen. Below about 50, blocky artefacts start to appear around edges and in skies. Screenshots with text look best at 85 or above.
WebP or JPEG?
WebP files are typically 25–35% smaller than JPEGs of similar visual quality and support transparency. Every current browser displays them. Choose JPEG when the image is going somewhere older — some desktop software, printers and upload forms still only accept JPG.
What happens to transparency and metadata?
JPEG cannot store transparency, so transparent areas of a PNG become white. Re-encoding also drops EXIF metadata such as camera model and GPS location, which is often a privacy bonus. If the compressed file comes out larger than the original — common with small, already optimised images — the tool marks it so you can keep the original.
Resizing beats quality
Halving the width of an image quarters its pixel count. If a photo will only be shown 1200 px wide, setting the max width to 1200 saves far more than lowering the quality.
