How to use Image Compression
Make JPG, PNG, WebP, AVIF and other images smaller in your browser, one file or a whole batch. Set a quality level, or enter a maximum file size and let the tool find the highest quality that fits. A before/after slider shows the difference before you download.

Frequently asked questions
Are my images uploaded to a server?
No. The encoders (MozJPEG, OxiPNG, WebP, AVIF, JPEG XL) run in your browser as WebAssembly, so your images never leave your device.
How do I get a photo under 100 KB or 1 MB for an upload form?
Choose Target size, then pick a preset from 20 KB to 2 MB or enter a Custom size in KB or MB. The tool searches for the highest quality that fits and counts 1 KB as 1,000 bytes. With Shrink dimensions if needed on, it also scales the image down when lower quality alone isn't enough.
Which output format gives the smallest files?
Usually AVIF, but it encodes slowly. WebP is typically 25–35% smaller than JPG at the same quality and opens almost everywhere. JPEG XL looks excellent, but few browsers can display it yet.
Why did my PNG barely get smaller?
PNG output is lossless: OxiPNG repacks the data without changing any pixels, so there is no quality setting. For a big reduction, switch Output format to WebP or JPG, or turn on Limit dimensions.
Are EXIF data and GPS location removed?
Yes. By default camera details, the capture date and GPS location are stripped. Turn on Keep EXIF data to keep them; this works for JPG, WebP and PNG output.
What happens to HEIC, GIF and animated images?
With Same selected, HEIC, GIF, BMP and TIFF are saved as JPG, or as PNG if the image has transparency. Animated GIFs keep only their first frame, so this tool is not meant for shrinking animations.
